Interfacing (DSI, CSI, I2C, etc.) • Re: Using SPI with CE0 and CE1

Yeah!

this github is 10 years old and I'm still using it!

long time ago I found a bug with the SPI speed.

1 - you need to set the spi speed

in lib_nrf24.py you need to add the spi speed.

Code:

 def begin(self, csn_pin, ce_pin=0):   # csn & ce are RF24 terminology. csn = SPI's CE!        self.spidev.open(0, csn_pin)        self.spidev.max_speed_hz=8000000        self.ce_pin = ce_pin
About your code
The second nrf24L01 should be
radio2.begin(0,25,1)
Also I'm no shure if you could use the same pin for csn_pin which is GPIO25 right now
