@petjepet the debug log will probably be the quickest way to find out

I had same issues and I didn't take separate regulator too seriously, which was mistake. So I made it work using a. separate voltage regulator b. capacitor cca 2uF between + and - pins on NRF24 c. using RF24_PA_MAX d. another device was about 2 meters away Before that I had only capacitor, and when I put voltage regulator it worked for me. I took power from arduino nano (+5V pin). No need for separate power. Powering Arduino Nano over USB is fine.

That happens because the voltage regulator from usb isn't able to supply enough current during transmission while when on battery probably it had sufficiently stable voltage for transmitting correctly.

@gohan That is a novel idea. Never tried it but i would think it should work as long as you can change the value on your controller. it should be simple enough to load the returning value into the sleep variable.

@Petjepet I've never used Pimatic so I don't know unfortunately. You could try the pimatic subforum here at mysensors (will hopefully get more attention there than in the general forum) or if pimatic has a community forum of their own.

It is not necessary for any esp8266 having a usb port as you program these directly via that usb port. So. indeed: the nodemcu doesn't need it and neither does the Wemos. The esp-07, also available, does need that setup to flash/program it.

I agree. It is very hard/difficult to keep a consistent set of libraries operational in a broader scope of elements to be managed.

Thank! I'll give it a try. I'm new in the Arduino world and hoping to learn from more experienced users.

I don't think there is a way to test it if you don't have sensors. Something needs to send data to it otherwise it will not do anything
