Radio FAIL after ~3 weeks [SOLVED]

ave a capacitor.
I will add power from other source.

Do you think I can initialize it with another Arduino but use VCC and GND from Arduino Nano, then connect back all cables from Arduino Nano and then it will work?

I don't want to restart Arduino Nano.

If you connect ground of both Arduinos, this should work. You should assign the other Arduino the same node id statically. Let me know the result if you try. :D

@Jan-Gatzke

I know how to solve my problem without restarting my Arduino Nano.

I initialize nRF with another Arduino.

NODE ID doesn't seems to be important, be careful how the sketch look like so you don't send any strange data when you initialize it. I used another CHILD ID and NODE ID, just to be sure, on the Arduino that I initialize it with.

Be very careful when you init the nRF from the second Arduino, you need to sync it with the first Arduino that is FAILING. If you init the nRF when the first Arduino is trying to send data it seems to NOT find the way back to send again. Then you get all this strange messages like: "version mismatch", "find parent" and maybe other messages.
My arduino sends data every 5 minute so I need to wait until it tried to send, when I see FAILED(in serial monitor) I disconnect all cables but NOT GND and VCC, init from the second Arduino and connected back the original cables. You must also connect GND from second Arduino to first Arduino when you init.

Another solution for future is to add gw.begin() in your loop, then it will initialize nRF in every loop, not very good solution but it works. If you send data every 5 minute I don't care if it will "talked" to controller every time it sends data, but for a battery powered node or a node that sends data every 5 seconds maybe it is better to find the real problem.

I think my problem was that the nRF have lost/forgot the init/settings or Arduino had a glitch so the nRF restarted but not Arduino.

Thanks for all help

hi friend i have same problem. in serial monitor some time i have this errors:

!TSF:MSG:SEND,5-5-0-0,s=1,c=1,t=2,pt=1,l=1,sg=0,ft=10,st=NACK:1
!TSM:READY:UPL FAIL,SNP
!TSF:SND:TNR

i use a 4.7 and 100 capacitor but i have problem yet. are you using a regulator module for your device ? so you have not any problem now? and all of commands send ? for me after some time i test relay and i see dont work , after some try this is work and some time dont work.... my device and gateway is 50 meter distance with a thin wall .

[flopp]

@Reza
What kind of nRF do you use?

I power my nRF directly from Arduino Nano.

I don't have problem anymore but maybe it will be a problem again in the future. I think your problem can be that the node doesn't have contact with your gateway.

Try to put a repeater in the middle between node and GW

@Reza
Which NRF Modules do you use? 50 meter with a wall in between wont function properly with the cheap ones. You need something like this for the Job:

!TSM:READY:UPL FAIL,SNP

I had not got such errors due to power issues. Unstable/insufficient power supply mostly resulted in inconsistent functions - not in steady errors. Sometimes (depending on weather? phase of the moon?) functions were ok, sometimes not.
Changing power supply (either batteries or buck-device) healed this problems.

So far I understand your error-messages they could probably mean what they say:
UPLink control FAILed and your node is Searching New Parent - which is a logical consequence.

I think flopp and Jan Gatzke are right: 50 meters is quite a large distance - may be too much for stable connection.

If your device is mobile - lower the distance (just for testing purposes) and look for a stable connection. Depending on the result you may take further actions like described above or - if you like tinkering - you may have a look at

http://www.instructables.com/id/Enhanced-NRF24L01/ or https://www.youtube.com/watch?v=NpMnauHeR7Y

I have not done this until now - but it looks really cool.

@tboha
Thank you friends for help. I use this models. Good communication is the first (but not send all command. Especially when I send quickly some commands)
But the main problem is after time. for example 1 hours or 1 day . when i want send a command , command dont send . i try again and again but dont work.

@Reza Your code isn´t easy to understand. More Comments within your code would be very helpful.

So I will try a little mind reading.....

Basic concept seems to be decoupling switches/pushbuttons from the relais part and to control the relais action through your controller.

Management of switches/pushbuttons is done in loop().

"Master of states" is your controller (software).

Actions are performed by receive().

At last a clean soloution - but some parts aren´t that clean.

The only reference to stateX is within receive() directly before digital_write(X). So any change to stateX from within the sketch will not have any effekt. So the introduction of the stateX variable isn´t actually necessary.

        digitalWrite(message.sensor + 2, message.getBool() ? RELAY_ON : RELAY_OFF);

should work to. This eliminates thes risk of double originals which can get very tricky if things go wrong. (i.e. there should be only one set of stateX variables in your system because keeping copied sets tidy is a huge amount of work and prone to errors).

In the first part of loop() you try to instantiate some basic mechanisms to accomplish this mission but I fear it will not succeed.

Within loop you begin with a chain of modulo-operations which might be intended to send the state variable to your controller once every hour (?) with 1 second interval. This will fail eternally if your loop starts accidentally with millis() at xxxxxx1 and loop duration is xxxxxx2. The remainder of % operation will always be 1 (or more) but never zero. Precise timing down to 1 millisecond would be too critical to little errors and is not necessary.
Spacing send() to one second should not be necessary either - MySensors framework can deal with lot of send() in a row.
So maybe a statement like

if (millis() >= lasttime+INTERVALL) {.....}

could fit your needs. It isn´t that precise - but precise enough and robust.

if (trigger == 0) {...;trigger=1;}

This part is executed only once because you never reset trigger to zero. If you intend to reset your controller variables you might move this part to setup() - or better leave it to your controller.

But if you omit stateX copying this whole section could be skipped.

The rest of loop() consists of switch management which seems ok to me. Nevertheless a little proposal for optimisation:

send(msgA.set(stateA ? true : false), true);

There is no really need for the trinary operator ? because stateA is bool, it may be send directly like

 send(msgA.set(stateA ), true);

debouncerA.update();

I am not very familiar with debounce(). But omitting "&&valueA==0" will cause your statement to react to pressing your button as well as to releasing your button. So this statement will act twice on one keystroke -- so far I remember the debounce() function.
Because stateA is not likely to be changed in this short amount of time, this statement will send stateA twice - which causes unnecessary traffic.
These are surely no crucial points but I think the sketch woud be more robust.

wdt_enable(WDTO_4S);

Please don´t do this - it may have terrible side effects and may make you mad while searching for errors.

So over all your sketch isn´t that bad for a first proof of concept and should be functional for your basic needs.

So missing send should be due to the qualitiy of your connection. Maybe a longer log of debug messages (both sides?) would be helpful.

@tboha

Great analysis. I will surely send you my code for review next time. :D

@tboha
thank you my friend for help
i am beginner and sorry for this sketch. i tried hardly until build this sketch with use other sketch in site. in this code i want use a 6channel relay with 6 button(toggle button up/down). also i want after power supply off/on , all relay go to off and in app (for example domoticz) show me all relay go to off. about millis() when i use a repeater (for this 6channel relay) and if repeater to be fail so radio in relay can not found a new way for connect to gateway. because that is not any connection with gateway. so if every hours relay send her state so if see that connection is fail so search and found a new way for connection.

sorry for weak in english :(

so you think my problem in connection is related to my sketch ? but i can not change this because i am beginner . can you help me to fix this code ? please

[Jan Gatzke]

@Reza

The Problem is most likely a problem with your hardware. Try to lower the distance and see if the problem still exists. If not you should replace your radios. Look for radios with pa / lna.

i test with lower distance . there is problem yet. i think problem is related to my sketch. i can not fix this :(

@Jan-Gatzke You are welcome.
@Reza : don´t worry, there will be a simple solution.
I´m in a hurry at the moment, I was ordered to do some party tonight. If my supreme command detects my current activities I will have very bad Karma for the next days.

To whom it may already apply: Happy new Year!! :boom:

I haven`t copied the code for all push-buttons - I leave this to you if this sketch is functional for your needs.

Acting carefully, you may mingle some parts with blacey´s sketch successfully (by the way - impressing coding style).

Reenacting your sketch I found some strange behavior: no reaction to push-button-press - meaning the sketch didn´t even take notice of the push-button after it had been pressed once - or sometimes twice.

Adding an external pull-up resistor (4.7k) fixed this problem.

So maybe it has not been a sending problem but a hardware problem (internal pull-ups to weak?).

Please flood your sketch with print statements - like "button A pressed" "send command issued" etc. and watch your serial terminal carefully and/or post your logs.

Thinking about the modulo-driven time-statement - actually it is a cute idea. Something like

 time_m = millis();
    a = (time_m / 1000) % 3600;

should make it immune to uneven starting values an even loop-cycle duration. (loop-cycle-time of the above sketch: approximately 125 µs)

These are the lesser problems. I fear you have to do some boring English lecture.
Please read: https://en.wikipedia.org/wiki/Finite-state_machine
https://en.wikipedia.org/wiki/State_machine_replication

and first: https://en.wikipedia.org/wiki/Two_Generals'_Problem
https://en.wikipedia.org/wiki/Byzantine_fault_tolerance

as an excerpt :

The Two Generals Problem was the first computer communication problem to be proved to be unsolvable.

This is not "we don´t have a solution until now" but: "it is sure there can´t be a solution"

So you will have to live with a certain amount of uncertainty .....

Conclusion:

1. Check correct function of push-button with Serial.print(), with and without external pull-up resistor.

2. Please post your logs afterwards.

3. be prepared to make some decisions concerning tolerable fuzziness.

4. if necessary start learning about scripting capabilities of your controller.

i have problem in send and receive ack ! i dont know where is problem ! i change radio and wire and arduino ... but this problem dont resolve :(

also in my sketch i want when relay module is power on (relays off (LED OFF) ) and when i send command LED on and relay on. also i use a key with up / down button. so i want when key is up send one command and when key is down send other command...
