Hi,
CC1200EM PCB has eight pin holes (P4 connector). I tried to connect these signals to raspberry pi but I can't do any SPI communications between CC1200EM module and raspberry pi. I also connect this CC1200EM's P4 signal to TrxEB's P7 20pin header but TrxEB's PER test can't recognize CC1200EM module.
I have some CC1101 RF modules, they can communicate with TrxEB's P7 20pin header via 4-wire SPI. Furthermore they can communicate with raspberry pi. Does anyone know why I can't communicate using CC1200EM's P4 connector?
Best regards,
