Serial GW and motion sensor functionning, but no activity between them

parachutesj

@Rolland as far as I know, you need a controller which assigns the node ID's - this of course means that you need a fully functioning setup from the beginning e.g. your gateway connected to a controller.
As a workaround you could specify the node ID manually. see my other post.

skywatch

@Rolland - The advice from @parachutesj is spot on! - You NEED a controller.

The gateway is only a conduit through which communications from nodes to the controller flow. With no controller there is no flow of data and so you will see little traffic. A raspberry pi is all you need, then choose from the available software downloads to act as controller. Simple!

parachutesj

@Rolland and you should put this into your code from both (if not there yet)

#define MY_DEBUG

Rolland

Ok guys, thanks a lot for all your advices. I understand better. @skywatch : my gateway is on USB port of a Raspberry Pi 3+ with Home Assitant. But on this side I don't understand fully how to configure the link between gateway and HA, or at least to see if everything is going normal. HA is powerful but there's so much to learn when you discover it.
I'm discovering a lot of things in a little time : Mysensors, Home assistant, arduino...
Thanks anyway for your help and kindness.
@parachutesj , I'll modify my sketch and see what happens.

skywatch

@Rolland The best way to see what is happening is to connect the gateway to the usb of a computer and open the serial monitor in the arduino IDE. Then you can see the values being sent by the nodes to test if it is working.
@parachutesj suggestion to add my debug to the config is also needed for this, but then reflash the node without my debug before you plug it back into the pi as it can cause issues. I never used HA so can't help you with that side of things, sorry.

Rolland

@parachutesj said in Serial GW and motion sensor functionning, but no activity between them:

try and put this into your code of the node
#define MY_NODE_ID 2
replace the number (2) for each further node with numbers between 1 and 255

what happens then?

Hi. Nothing change. I still got the same 3 debug lines, no sign of communication between node and gw...

Rolland

I've also tried to clear the eeprom memory of the node, and flash again sensor sketch, but still the same problem... i've also tried to see if the motion sensor was working correctly, and made up a simple sketch with just the sensor and the Arduino, it's working fine.

skywatch

@Rolland Does the motion sensor go HIGH or LOW when activated?

mfalkvidd

as @electrik mentioned, the sensor node does not complete its initialization of the radio.

Therefore, it does not (yet) matter if node ID is defined, or how the motion sensor works. The node never reaches any of that stuff.

@Rolland if you can, replace the radio on the sensor node. If that doesn't help, try replacing the Arduino. Also try to disconnect everything but the power and the radio from the Arduino.

parachutesj

@mfalkvidd true.
this is the log if the radio works and it does not have an ID. just uploaded to a blank Nano

if I "kill" the radio, it looks like this, which is still different than what @Rolland got. But would be worth a try to replace the radio.

almost forgot:
to just eliminate the issues with ID, missing controller etc. You could test the radios with a simple NRF24 test script, just google "NRF24 test code" and you will find a bunch to test if the communication works between nodes and radios are ok.

skywatch

Photos of your hardware would be good as 'nano clone' and 'nrf24' come in lots of types and qualities...

Rolland

Hi everybody.
I'm progressing, thanks to you. Here is some more infos :

@mfalkvidd and @electrik , ok thanks a lot, i'll put the ID part of the plan aside for a while. Following your advice, when I unplug everything but the power and radio, I've got some weird things happening, worst of all is a sudden crash and reboot of computer when I try to open serial link monitor... :-x
@skywatch : nano clones are these ones, and nRF24L01+ are those ones.
@parachutesj : i've tried some very good sketches and begin to see a little clearer about nrf24. Using TMRh20 libraries and sketches, I've tried to make a couple of radios+nanos to communicate. The result I got is not so good : One radio just made my computer reboot :-x , while the two others seem more stable, BUT, when sending the ping between the two of them, the serial link console freezes for a little while, then shows back the sketch from the beginning. From what I've been reading, I think this could be a power supply problem (this post, "Power problems" section. I'll try to connect capacitors between VCC and GND of radios to avoid this "freeze" and "reboot" symptoma.

Next steps for me would be (I think) :

see if capacitors can do the job and solve the problem
try some other radio modules maybe ?
try an official Arduino nano maybe ?

Again, thank you all for your help !

skywatch

@Rolland I was hoping you'd post a photo of what you have made so we can see the wiring etc.... But, you have unshielded pa/lna radio modules and I suggest getting some non-pa/lna ones from cdebyte on aliexpress.

How are you powering the radios?
What are you using to power the nano?

parachutesj

@Rolland unfortunately I have to confirm what @skywatch said: the radios are crap. I had those and never made good experience with them. Also the amplified long range radios are not really needed in most cases and if, then they need a really good power source to run otherwise I never got stable connections.
Besides, any cheap NRF24 from China worked quite well for me. Some very few were faulty but if you get 10 for 7 USD you can live with that

Not saying those are the best, but easier than the PA-ones.

parachutesj

@Rolland don't bother with official Arduino (imho). the clones work flawless. I have a lot here in my home and they work well. It is just not worth it to pay 10x the price

skywatch

@Rolland these are the modules I would recommend.....

Rolland

Hello everybody. Ok, I've made some shopping, according to your advices, waiting for items to arrive. Until then, see you soon and take care, thanks again. I'll post the results of the new combination, hoping for success.
Ciao.

skywatch

@Rolland That is good news - what capacitors did you get for the NRF24's ???

Rolland

@skywatch I've got some 10 µF and 100 µF electrolytic capacitors, and just received a bunch of other various capacitors, ranging from 1 to 470 µF. I haven't tested them for now.
But good news ! I also received 3 NRF24L01+ with built in antennas, reset the entire crew of nodes and gateway, and it works like a charm :blush:
I'm more than happy. Thanks again for all your advices.
I'll post some news later, testing the capacitors with NRF24L01+ and antennas.
Ciao.
