first post here, even if I'm lurking from several months ago.
My name is Stefano, I have some experience with Arduinos, Teensy, ESPs. I'm running an Home Assistant controller, and I'm already using some basic MySensors nodes.
I'm experimenting with a test node where the Arduino Nano is powered via USB and the NRF24L01+ radio is powered from 2 AA batteries in series.
The node is booting up (I get MySensors banner and data in serial console) but the radio does not initialize.
I understood that the NRF24 can be powered directly from 3V batteries, isn't it?
If I connect the radio to the 3.3V and GND pin of Arduino it runs ok. It's just when powered from batteries that it doesn't initialize...
Some context information:
- all the others radio's pin are connected to the Arduino in the same way both when powered with batteries taht when powered from Arduino
- I checked the batteries with multimeter and they, in series, provides around 3.1Volts. I think it's enough, isn't it?
- Why am I doing this? well I'm trying to test if I can get better radio performances by powering it from a "cleaner" current (batterties) instead of the 3.3V from Arduino.
Thanks for your help
