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

@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? -
@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. -

@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

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 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.
