I have a 3.3 V Pro Mini connected to nRF24l01 as xmtr. The nRF24L01 does not respond to the Pro Mini. Any help will be appreciated.
I have attached the print detail output:

The top transmitter output is before I changed the nRF24L01 module which appeared to be bad. The second transmitter started output. Module is good but nRF24L01 would not connect to receiver with 3.3 V Pro Mini. It connects if I use a Nano.
