Hi I have just started to study RF24 library for remote communication, I have two arduinos : UNO and Mega. I have connected this remote modules to them, also by this time I have soldered capacitor between + and - on power lines, because a lot of people suggest to do this, because sometimes voltage is unstable, So tried Getting Starting example it works , but firstly it worked weirdly . Sometimes data has been passed , but only from one to another not vice verse. But than it started work normally, I need to fire up 7-seg led remotly using communication with these modules.And sesniing data to transiver with the remote controller.
It compiles and show remote conntroller clicks but it cannot connect to another device. Here are my scatches , pleae have a look maybe there is a problem in code.
