Hi, I've been looking at the CC2420Transmit component and have some questions. First, I would like to know what are the units of the backoff time; some comments in the code simply indicate that it is unknown, but I guess that since the timer used to measure the backoff is a 32khz- based timer, then the units should be in 1/32k. This is correct? According the code, when a packet is going to be sent the radio backs off for an 'InitialBackoff' amount of time; after that, the channel is sensed and if it is free then another amount of time equals to 'CC2420_ack_turnaround_time' is waited before really attempting to send the package. Is this interpretation correct? Finally, I would like to know how many attempts to send a message are performed if the channel is busy; by looking at the code, it seems that there are not bounds and that infinite transmission retries will be performed if upper layers don't stop them. Am I right? Thanks for your help.
