Hi NXP :


After UPDATE_RF_CONFIG and LOAD_RF_CONFIG, that the value read from the Register 0x20 is different from the value set by UPDATE_RF_CONFIG, and only the Register address: 0x20 has this problem.



Setting log :


---Set RF configuration byte: 0x00, Register: 0x20--------------------------------------------------------------------
