Hello, Alexander; I'm using a micaz, so it is CC2420 indeed. I've looked into the Zigbee specification, 802.15.4 frame formats and understood (I believe, even if lightly) the frame formats. But I am not sure of what the 32 bytes I receive are, exactly. Is it the complete PPDU? There is a group (Address Information) that is from 0 to 20 bytes, and I dont know if they're there and if yes, how many. Neither do I know for sure if I am actually receiving, within those 32 bytes, the SHR and PHR of the PPDU or if I only get the MPDU. That is the difference between understanding if the 32 bytes are caused by the inclusion of the SHR and PHR in the frames i'm reading from the serial port or if I'm only getting 32 bytes because of the 20 bytes from the Address Information in the MPDU. Sounds confusing because i'm confused too!
Thank you for your reply, Alexander; Sincerely, Pedro On 6/11/07, Alexander Becher <[EMAIL PROTECTED]> wrote:

For example, for a CC2420 radio, you can read in its datasheet that it uses IEEE 802.15.4 packet format, and that standard gives you the exact packet format.
