NRF24L01 radio not connecting

See https://forum.mysensors.org/topic/8869/troubleshooting-communication-solved for more details on a similar case. You have found the same solution as I did: find something to extend the antenna

Thanks!
The NFR chip is oriented in such a way that the antenna is way outside the PCB. So I'm not sure that this is he problem.

@kontrollable ok. Good. Then it is probably something else. Have you looked at the troubleshooting diagram at https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ ?

Debug logs from the node and the gateway will probably be very useful when troubleshooting.

@mfalkvidd Awesome! I will check the debug logs from my node and gateway this evening.

OK, so enabled MY_DEBUG on my serial gateway. MY_DEBUG was already enabled in my sensor node.
I found that the gateway did not receive any signals from the node at all.
The node reports that it does not find any parent.
So my conclusion is that the radio on the node sends a weak signal.

Here is the log from the gateway:

I used a multimeter to measure 3.3 V on the output from my voltage regulator. 3.3 V on the radio chip and capacitor. So it seems to power the radio alright.

Is there a reason why are you still using version 2.1.1?

@gohan said in NRF24L01 radio not connecting:

The only reason is that I have not bothered to update. But do you really think that updating would help? Could it really be a software problem?

Always stay up-to-date as many bugs get corrected

Oh my god! Updated the sensor (not the gateway yet) and now it seems to work! Am I surprised? Yes!
Thanks so much!

@kontrollable I think you should update the GW as well. I had a lot of problems with downlink messages from GW to an RGB controller. Updating the GW solved all of this immediately.

@bgunnarb Thanks, I did update the gateway also.
