I read the tutorial of @Robin2, they are really valuable things, I've read them and I really took many notes and highlighted. But there is a question in my mind;
I will use 2 TX and 1 RX. And I want each TX to use different channels to send data without interference and simultaneously. However, as far as I know, to do this the RX node must listen to two channels, it doesn't matter to read pipes simultaneously, we can read the buffers in order. The important thing for us is sending data simultaneously without interference. Is it applicable?
