Ok.... so you're saying that those NRF24L01+ modules worked fine with the nano until you did that thing....where you selected (in the arduino IDE software) the incorrect board details from the menu, right?So if it was all working just fine before that event, then grab a spare nano, and some spare NRF24L01+ and even a spare computer ..... and test the whole lot. If you reckon something happened only after that 'wrong board selection' thing, then we need to see if we can at least get back to square 1 again.
And you're saying that your devices were working great at one stage ..... so chances of getting back to square 1 should be 100 percent.
Arduino nano 3.3V output can dish out (max) 50 mA or so, right?
If selecting the wrong board type caused the thing that read the code to be "deleted" can I just reupload the programmer or something?
Did I mention thay whilst the radio is connected to the nano, upon clicking the serial monitor the IDE says Error selecting port parameters. I found a workaround where i can access the serial monitor which resulted in me finding that the radio is reading falsely.
