I am using Arduino pro Mini and nRF24L01+ to transmit data. All analog pins and digital pins are being used to create and transmit the array.
The program is working properly except for the RX pin (pin 1). The value is not changing after pressing the button on the receiver end serial. I also checked soldering but got no relief. Below are transmit and receiving programs, please guide.
If you wish to use pins 0 and 1 for normal I/O, you cannot use them for Serial RX/TX as well. It's one or the other.
Instead of using pin 9 and 10 as CE / CSN, can i use 0 and 1 as CE / CSN?
You can, but you still won't be able to use Serial Rx and Tx as well if you're using pins 0 & 1 for I/O.
