Part Number: CC113L
Hi
Configuration supplement：Base Frequency（433.00MHz）Deviation（39.6kHz）Data Rate（19.2 kbps--After encoding, 38.348.）Modulation Format（2-FSK）Encoding（Manchester）Preamble（(0x5555 5555 5555)）Sync Word（0x569A）
When I configured CC113L with the following parameters, the laboratory test showed that the reception rate was close to 100%.
NRZ code reception, reading data from the FIFO, Manchester decoding is processed by software.

After enabling the Manchester decoding of CC113L, the reception rate is approximately 70%. The configuration is as follows.
Attempting to modify other configurations did not result in any significant improvement in the reception rate.

I hope somone help me solve the problem.
