In order to compatible with Si4438 packet. How to set CC115L CRC as below format? Thanks a lot.

1. When enable Si4438 CRC, Si4438 can't receive packet from CC115L

2. Once disable Si4438 CRC, it can receive packet from CC115L.

The CRC generated by CC115L is fixed and can't be changed. But what you can do is turn off the insertion of CRC on CC115L, calculate the CRC in the MCU and insert it as the last bytes of the payload.

The MCU is MSP430G2453, is there a CRC checksum example code ? Thanks.
