btw, you didn't answer my question, is there a trusted NRF/PA/LNA seller,
I cannot make any guarantees. But ITead should sell the genuine thing.
it was my assumption too ...
If I enable debug, will it provide me more info about communication ?
@hek said:
I don't think it should search...
https://github.com/mysensors/Arduino/blob/master/libraries/MySensors/MySensor.cpp#L463But you might wanna try the development branch anyway to see if you notice any difference.
I can try at the next occurence... as I have no more idea... I think that code is clean, and problem is rather on the NRF. Maybe a starvation of something after a while, I don't know. difficult to say.
btw, you didn't answer my question, is there a trusted NRF/PA/LNA seller, with a tested NRF24 tested by you, and working at it should ?
@sundberg84 I use the last version (I guess nov 2015).
@hek it can be the case ? trying to use another route.
There is no other route available normally. I have disable repeater mode on all powered sensor.
Could it be a bad NRF24 ? is there a brand well-kwown really trusted ?
@hek ok 
Yes of course, I tried, it doesn't work...ceiling is really too thick !
12H03 - 12H23 We can see clearly the drops... 
and I have st=fail.
I resend packet based on st=fail, but resend is dropped also
@hek My antenna is powered externally directly in 3.3V with 4.7uF...
What is vanilla radio ? distance is 5m, but a big ceiling is in between...
@hek said:
Agree with you. Very strange. Especially when you use a direct route to gw.
the strange thing : I receive alsmost 19000 messages without issue.
When it happens for the first time, the issues are more and more frequent.
the NRF PA LNA provided by ITEAD should be good, no ? Which PA LNA are you recommending ?
One more thing, when problem happens, and recover, I tried to make a reboot from my controller, and the WS is not longer communicating. I have to power down/up to recover
@hek "Could the issue be between gw/controller?" ... I have a st=fail so it shouldn't be between controller and GW ?
@hek said:
I looked in the other sensors (sensebender at the same time). I have 5 sensebender, and there is no drop at this time. Packets are received every 5 minutes during this period. So, I don't expect a freeze of the GW.
I use JEEDOM.
I don't expect issue between GW and Controller ... but it can be a lead.
it difficult to troubleshoot controller. Because it's a serial GW, if packet doesn't arrive to the controller, I can not check at the GW level, as there is no way to connect.
@hek, as explained in the previous post, I enforced the next hop (GW).. so, it shouldn't used another route ?
gw.begin(NULL, 102, false, 0);
here is my config.
@hek Nope, I don't have any microwave running when I have some drops.
I don't have microwave oven at home. Just a TV. It was shutdown during events.
Th eweird thing, is that it doesn't work for 15 minutes. I loss 3 rows (3X10 messages) with 5 minutes interval.
It means that's the issue happens for a while. After, this event, everything runs correctly.
During the event, I have another sensors ( 5 sensors sensebender) which send correctly a packet. It means that issue is not on GW. And anyway, I don't have issue with GW.
I have a big ceiling to pass through. On GW and sensor, I use 7db antenna.
I don't understand why it works for 6 days, and stop suddenly for 15 minutes !
@sundberg84 . I forgot to mention, that the route is enforced to 0. There is then, no computation of route, and the route is direct. When I have st=fail, my packet doesn't arrive to my GW, as my value doesn't appear my controller. I use a Serial GW, if my packet doesn't arrive to my controller, I can not check more. As the problem happens suddenly, I can put a sniffer in the air also.
Hello team,
I post here, as I'm lost.
I built a weather station based on arduino mega 2650 + PCB shield that I made (100 hours on this project -> 50 for troubleshooting).
I use NRF24+PA/LNA with 4.7uF cap (I tried 100uF, with same result). The antenna is powered externally. I use RF24_PA_MAX. But using RF24_PA_LOW gives the same result. "Nov 6th 2015" Library version is used.
I send 10 packets every 5 minutes (each packet in the raw is sent every 100ms to avoid any starvation), to bring the different value of my station.
Everything works correctly during 6/7 days, after, I start dropping packets. For example I don't receive anything for 15/20 minutes, and it comes back working !!! the strange thing, is that, I was expecting to loss some packets sometimes, which is a normal behavior of wifi. However , I loss packets in the same row during 20 minutes or 10 minutes, really weird, is there a starvation of something ? I don't know, and my knowledge about electronic is below the need to move forward.
during issue, I have st=fail on the station. If I resend packet based on the ack, the second packet is dropped also. In fact, everything is dropped during the issue.
As I report some rain value, I can not drop packet.
I tried to change a lot of things without success. My PA/LNA has been bought to ITEAD? and should be a Nordic one, it is sold like this.
My weather station report the good value WITHOUT any drop during one week.
It means that I receive 17280 packets without any drop !!!
I followed all the golden rules (I assume I would say), and I have no more ideas on how to troubleshoot deeper. Should I enable "debug" in myconfig.h ?
Otherwise, is there a well known PA/LNA that I can buy, and be sure 100% that's the nordic, and tested by you guys ??? I am almost ready to leave out this project in favour of Netatmo, because, I don't know how to move forward now. I passed 50 hours to troubleshoot, making some tries in all directions without success ! I send a bottle in the sea, it will be my last hope .
thank you in advance
@rvendrame Hello,
yes, I use this already. But as you know in a repeater, the gw.send is not available as it's include in the process() function... I do nont have access to gw.send...
everything is in the title
I'm wondering how to increase reliability on bad RF transmission (big ceiling).
I want to do a resend when st=fail.
I do it already on my sensor, it's easy to code, as it's in the sketch directly.
I'm wondering how to do it in the repetear ??? some ideas ???
@mfalkvidd not false I have to make some tries also. I bought a gold platined sensor, I hope that corrosion will be less...
@m26872 I agree, sometimes packet reach the next hop, but the ACK does'nt come back ... I saw that... I was receiving the information on my controller, but this message was not acked properly, and I had a st=Fail ....I think it can happen when we are using 2 different type of NRF24 (NRF24+PA+LNA vs NRF24)... one is sending more far , and the ack can't reach because it does not have enough power ...
@Dwalt Hello,
In fact, I posted a new thread, because I don't understand my problem... (and it's not , 'im sure now, that it's not on the node, but on the repeater 100% sure)
I use 1.5 (but the one from august, the one just out of the box, I think they had some changes since).. I saw some bug fix (see below the thread corresponding)
You are using the 1.5 but what is the date of the file in the library (me it was august), I understood, that there was some changes... a bug in the library. My problem is very very similar, but I can be sure 100% because, when repetear stuck, I don't have serial connected to log. However, I see the led blinking a lot meaning that there is a lot of communication happening... a loop for example in a send message If I connnect my USB repeater reboot, and problem disappears..
From now, I have just disabled the "reset" when plugin usb ( a 120ohm between RST and 5V). Next time I will connect to check what is grabbing on the console.
see here : Repeater nood keeps looping... and doesnt reach gw
In the mean time , I upgraded to the 1.5 library, the one from november...
let's see, but I'm on this issue since 3 months !!! I'm quite lost, and I don't know exactly how to move forward now
Hello,
I'm on the same project personally...I using 2 battery... this part should work between 3.3 V and 5V...
finally with 2XAA we only have 3V, and the max value for me is 750 not 1023... did you get 1023 when into the water?
I use a gold plated sensor, and the plug will be into a seal to avoid corrosion and water to go in.
I use a sensbender where I connected on A3 the pin use for the soil moisture sensor.
Could you confirm that change the polarity help to avoid corrosion ???
thanks
Hello Team,
I think I fall into the same issue. My repeater goes into a loop (led is blinking continiously), and nothing is not longer working on the repeaterI changed everything (nano/NRF PA/LNA). NRF is powered externally, adding Cap also. Issue seems like to be the same. I can't connect full time in USB because my repeater is outside. Repeater stuck after between 1 day and 2 weeks.
I have a serial console on the sensor, and after a while, packet are sent st=ok, but packets doesn't reach the GW which work correctly...
I use library 1.5 for the repeater / node / GW (downloaded in august)... I don't understand the conclusion !!! What should I do, downgrade to 1.4 ??? what is the line code changed, to compare if I have the fix into my library already...
please advise, I'm working on this issue since 3 months without any finding...Should I clear the eeprom ?
Thanks a lot !
happy to help
I still have some issue. My repeater nano freeze after couple of days... it's blinking quickly (RX?/TX?)... and I lost the connectivity. I have to reboot it. Only node connected to this repeater stuck !
I don't have a cable connnected to it...then I don't know what type of error I'm facing to
@Oitzu Yes of course, I'm using a Buck power down socket ( the one recommended on mysensor.org)
thanks
@Oitzu Thanks. I will test it ungrounded first.
For the nano thanks also for your reply, it's great to have confirmation that nano can not really support NRF+PA+LNA with RF24_PA_MAX parameter, which is my case.
I hope , that powering direclty from a USB will avoid any more issue, that I'm hitting...
thanks again
@mfalkvidd thanks for your reply.
If we want to ground it, can we use the gold base ? I guess that this part is grounded....
I met some issues with PA LNA, do you think that it can freeze after a while, and powering the NRF24+PA+LNA directly on the nano ? It seems that after one month of use, I loss many packets..
Finally does the foil should be grounded or not ??
thanks
I answer myself, hope it will help somebody else ...

HEllo,
I have the same issue... did you fix your problem ?
your peace of code is nice.. but on the controller you received 4 times the same message, which is not very convenient ? right ?
I have almost the same.
In my node , I have a serie for a time, message are received by GW, but the ack is not sent properly... It's always the same child with the problem. Sometimes, the child 3 works, sometimes not... I don't see why this one !!!! and most of the time everything works !

We can assume that the issue is on the first hop....
But the st=fail means, maybe, that the message has not reached GW.... in both case, drop on 1st hop or 2nd Hop(GW) result in the same message...
The test would be to generate a wifi issue between GW/repeater, and see if the node has a st=fail or st=ok
I don't have 3 PC to test... May be @hek can answer he made the protocol ...
It will help a lot in my Troubleshoot. In fact, I have issues with NRF... I tried different, one. I have one working well... now, but still want to confirm in case of...
This one seems to work

Thanks for your reply.
In fact, I'm use to work with Mysensor, I have many sensor.
In my case, it globally works. My concern here, is that I made a PCB Shield for my weather station.
My weather station is on my roof, I'm looking to place the repeater at the right place to avoid the maximum of loss. SO I made a lot of try everytwhere... My concern is really to understand what does mean the st=fail. Deos it mean : 1) the message has not een received by the GW, and message can be drop anywhere 2) The message has been dropped between the sensor and the repetaer only.
I just try to understand where the message is drop to optimize the distance/reception of the problematic segment.
PS :I don't have at this time, some monitor, as I have to go on my roof to
thanks
hello team,
Just an easy question. We have this Sensor<-> Repeater<-> GW
On my sensor, If I receive a "st=Fail"
Does it mean that issue is between Device <-> Repeater (then the first hop)?
Or issue is that message has not been received by the Gateway, I mean packet can be drop either between "Sensor<-> Repeater" or "Repeater<-> GW"???
thanks

Yes I use NRF24.it's not a wall, but a ceiling with a steel mesh inside... I have the capacitor, and I'm use to work with NRF, I tried many of them china, or other items... I don't have any issue in the flat...
In fact I have a window , but the gateway is undo a stair made 100% of steel... and a lot of message doesn't reach the destination !.
Hello Thanks for your help. I understand now why I didn't see anything.
I have another question, I need to send the message from my Weatherstation to the GW, however the ceiling is pretty thick and nothing is passing though ... Even with repetear , I can't cross the ceiling.
I have an Ethernet cable there, do you think that we can carry something over it ? or is there some solution for this kind of case. I guess that some people got this issue also ...

Hello gurus,
I created a repeater node for my weather station, as it's clearly too far.
When I start it, I don't see any message from some other nodes... My repeater starts correctly and it communicates correctly with the Serial GW.
So my question is : why I don't see any exchange, I mean no "read" , no "send" as I have a lot of sensor from now. Does it mean that once the route is calculated (and not passing through Repeater), the repeater doesn't repeat those messages ?????
please advice... I'm stuck !
I didn't see any working manual for repeater, just how to code it.
thanks
Hello,
You code just remove multiple pulse during a short period of time, like a push button.
My problem is different. I have to remove the first random pulse ! Each pulse is important for me as I use it for my gaz cooker.
In fact, I found the solution, I remove the IRQ interrupt. The reed switch clode around 250ms. So I test during each loop. If the switch is close, I wait 30ms and test again if switch is close. If it is still close, it means that's not a false postiive and I can count a pulse.
I have the code since 1 week, and it works properly without any false pulse.
In fact my solenoide valve is too close from arduino and it make some interference I can't remove with capacitors...
Here is my code:
if (state != laststate)
{
delay(30);
if (state != laststate)
{
delay(30);
if (state != laststate)
{
if (state == HIGH)
{
unsigned long newBlink = micros();
unsigned long interval = newBlink-lastBlink;
lastPulse = millis();
flow = (60000000.0 /interval) / ppl;
lastBlink = newBlink;
pulseCount++;
Serial.print("pulseCount:");
Serial.println(pulseCount);
Serial.print("interval:");
Serial.println(interval/1000);
state = laststate;
flow = (60000000.0 / interval) / ppl;
alarm_flag = 1;
// state1 == true; // un pulse est apparu, on demarre l'alarm
lastBlink = newBlink;
alarm1 = 0;
alarm1_t = millis();
}
if (state == LOW)
{
state = laststate;
}
}
}
}
}```Hello Team,
I have a concern
I created 2 sensors. A waterpulse counter based on Reed switch and a Gaz Counter based also on reed switch. For the waterpulse counter, the .ino is the one provided on the mysensors website. My problem is that I have some false positive.
WhenI just plug the arduino in USB on my MAC, it works. However, If I connect it from a power supply 220V ( vin or USB), I have some issues, and I have some pulse even if there is nothing. For example, I have a soleniod valve, if I switch it ON/OFF, it troubles the Reed IRQ signal and I have a false pulse taking in account...
So, my question is how to remove the interference. I use the reed switch in pullup, and I applied a 10uF capacitor on the reed switch.
Should I use a specific powersupply with a filter ???? I'm lost I made some tests during 6 hours without any good result.
please help...
@hek Of course it's difficult to predict, it's just to have an order of magnitude, specially if I want to use a CRV123 3V battery. I don't want to change it every 2 months. One year should be good.
@hek I computed that sending a value every minute with a 10 seconds of communication every minute (wakeup), the autonomy for a single 3V 1500mA CR123 lithium battery is around 1 year (312 Days). Around 2 year for a dual Lithium AA, I guess.
If there is 5 second of wakeup every minute, it's 500 days for a single cell CR123.
Purely theorical... but it gives an order of magnetude.
I didn't find mention of it. What is the expected battery life ?
I was going to replace AA by CR123 to gain in space.
thkx
Yes of course...anyway "version mismatch" should not appear due to wire issue
I reply myself. I think that it's simply not compatible as far as I read...
I will buy some new "true" nano...
Hello,
I had some issue with my serialGW nano... I have some msg st:fail.
I guess I have some HW issue with my fake nano (made in china)...
I don't have more nano in spare.
I have only UNO.
I uploaded the serialgw sketch, but he tells me "version mismatch".
I don't know where does this message come from, and which version we are talking about... Could you help me. I don't have serial gw from now, and It's quite annoying... thanks
.
@AWI Hello, I put a stepdown module on the both end, added a capacitor. I change the myconfig.h file to put RF24_PA_MAX on RF24_PA_LEVEL and RF24_PA_LEVEL_GW . The result was a little bit better, I'm not even sure . But from now, result are good, I switch back my current antenna by the original one delivered with the module NRF24+.
in fact, I installed some big antenna (I have some spare with my routed wifi network), but I think it was a mistake. With the NRF24 bulk antenna, it works really better, I have some others tests to do...I will keep you informed in the coming days. thanks again for you help
@lunarok said:
CHILD_ID
By the way, if I write this "gw.present(CHILD_ID, S_WATER);" , it means that it's only one sensor, and is not able to store 3 differents values.
Look the screenshot. If I don't declare 3 sensors image, I will have only sensor number 5 for example Hence only flow is reported... in this case, 0 (as there is no flow rate).
When node register to gateway, it present itself with one sensor and only one value....
Or maybe it's a jeedom issue, and jeedom is not able to understand 1 sensors, carrying 3 different values...
@AWI That's clear then.... I didn't know that 5V on uno can draw 450ma... ON their website, they precise only I/O and 3.3V... From now it's very clear. I will use the 5V pin, with "something" to reduce it to 3.3V...
I have this in stock : http://www.ebay.com/itm/Mini-3A-DC-DC-Converter-Adjustable-Step-down-Power-Supply-Module-replace-LM2596s-/261328784505?ssPageName=ADME:L:OU:FR:3160
a power down module, IN="5V" OUT-"adjustable (including 3.3V)"
Do you know for the nano the +5V max draw ?
Thank for your help, grandly appreciated.
@AWI I confused from now. This adapter allow to convert 5V to 3.3V. HOwever my problem right now is a problem of consumption. It seems that NRF+PA consummes 100+Ma... each I/O pin on arduino is max 50Ma... I wil not solve my problem to put a 5V to 3.3V ? I need to add a new power source able to provide more than 100ma or more ? correct ?
@andriej These value are reported into the same Variable... so the GW receive 3 different values sequentially...I guess that behavior should be the same on domoticz.
Hello Team,
I'm using the water pulse meter ino file with jeedom.
I made some change like this :
gw.present(CHILD_ID_FLOW, S_WATER);
gw.present(CHILD_ID_VOL, S_WATER);
gw.present(CHILD_ID_PCMSG, S_WATER);
gw.request(CHILD_ID_PCMSG, V_VAR1);
Compare to the orignal one :
gw.present(CHILD_ID, S_WATER);
gw.request(CHILD_ID, V_VAR1);
I f i don't do this, there is only one child presented to the gateway, and all 3 counters are sent in the same variable. The results on jeedom is only one value is recognized, and when it receives 3 values for the same thing, the variable in jeedom takes 3 different values alternatively... by the way, the gw request VAR1 doesn't work as it's taking the wrong variable...
From now, it works with these changes, but does I miss something ?
The right result is presented in the image below. As you can see we need 3 different variables in jeedom.
Make sense ?
@korttoma mmm... that's pretty much clear from now. we are then close to the limit then...which kind of power module is recommended ?
This one sounds good ? :: http://www.ebay.com/itm/1Pcs-New-3-3V-5V-MB102-Breadboard-Power-Supply-Module-For-Arduino-Breadboard/281372556250?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D29266%26meid%3D1f59438fd24b4f9eb809f216f307ad1a%26pid%3D100005%26rk%3D5%26rkt%3D6%26sd%3D181718046489&rt=nc&autorefresh=true
it allows to use with one 5V input, and Two output, one is 3.3V and the second one 5V.... do you have a better idea ? thanks in advance rgds.
@korttoma In the arduino doc, it's 40ma for 3.3V pin
http://arduino.cc/en/main/arduinoBoardUno
I read in the nrf24L01 doc 11.3ma;
Transmitter
x00 Programmable output power: 0, -6, -12 or -18dBm x00 11.3mA at 0dBm output power
β’ Receiver
x00 Fast AGC for improved dynamic range x00 Integrated channel filters
x00 13.5mA at 2Mbps
So it should be enough no ? Did I miss something ?
@korttoma OK. Thank you. Should I use an external power source for both GW + node ? If ext power use, I can keep the level set to max ? In fact, what is the best way to get a maximum range ? Also, should I connect a capacitor ? thank you by advance. rgds
Hello,
I use 2" nRF24L01+ with PA + LNA " bought on ebay.
I connected the arduino directly to the nRF including 3.3V.
I feel the distance very very short. Maybe 4 meters with a Wall... Should I define RF24_PA_LEVEL_GW to max" ?:
#define RF24_PA_LEVEL_GW RF24_PA_MAX ???
Can I expect something better ?
Or should I use a specific 3.3V power supply which is not very convenient ?
rgds
thanks
@hek I know , yes for the T/H sensor. As we put 2 AA battery, we have to know if we want to stack sensor/battery or not...otherwise, battery and sensor will be on the same plan.
I think that we can start without extra sensor, and add it in function of request, I'm going to buy a 3D printer, It will be my first tests.
@hek Hello, I have a friend who is working with 3D modeling. i can study it. I do not guaranty for the moment, as it doesn't rely on me directly. however I can do the best, and try to move forward.
If I understand correctly, we need the place for the sensor+antenna+AA battery...
On the PCB, is there some hole to place some screws ?
How should we close the case ? by putting some screw or just putting a cover ? make sense ?
@hek Thank you for your reply. I'm going to deploy may be like 5/6 nodes. Another question, By any chance, did you think about a case which accept module+battery ?
To where will you be able to ship the nodes ? I live in France. I don't know where you are located...
Hello team, thanks for the great job. This tool is very useful.
however, I don't understand how the tool can snif. I guess, that I have to connect an arduino in serial ( I use the tool in a VM)... but with which sketch ? a gateway sketch...I think I missed something, but if somebody can elaborate a little bit. thanks
