Hi Peng, > Question1: Is this the message type eventually download to the RF chip > buffer and send to the air?
Only the message_header, message_data and message_footer is downloaded and sent over the air. The metadata is neither downloaded not transmitted. > Question2: As I want to keep the probabilities of 1s and 0s are as equal as > possible, my idea is to find the field which has been fixed eg, src fcf dsn > etc. and the difference between the number of 1s and 0s of these field and > compensate in the payload field.

I would recommend you to read the RF230 datasheet from Atmel and figure out the packet layout. > Question3: Is these there filed plus TOSH_DATA_LENGTH equals to the final > packet length? Or we have something else. The final packet length has nothing to do with TOSH_DATA_LENGTH. Just add together the length of message_header and message_footer structures plus the length of the payload as you specified in AMSend.send.
