I have been working with two radios CC1101(each one with its CC1190 for power amplification) connected each one to an Arduino-due Board and they have been communicating properly. However, I have faced trouble when the message sended is less than 12 Bytes. CRC throws at reception, 0, resulting in packet error (crc_error). I have tried forcing it to 1 but the radio sets the source address undefined. Has anyone faced a similar problem? Any suggestion for solving this issue would be really appreciated.
