Dear Sir Madam
We are working on CC1121 which is interfaced to 8051 core microcontroller.
The Transmission is seems OK as we are getting the GPIO status while transmission of Data.
But we are not getting the data at receiver end.
Can you please help to support here.
Attached is the RF receiver.c and transmitter.c file.
