I have a project which needs to be sealed making it impossible for me to code it using USB once I have it set up. I'm using a Pro Mini with a RF24 module (which will be sealed) for communication with a Uno with another RF24 module (which can be connected by USB). Is there any way I could put a sketch on the pro mini using just the RF24 module In short, can I program the atmega328 wirelessly through nrf24L01+?
Any kind of help would be appreciated! Thank you :)
