I do not know what resolution you are using. It definitely retransmits the same packet over and over and in fact it uses some random backoffs of the order of up to 2 ms. This is the default LPL mode. > In BoX-MAC-2 the transmission is spaced, right?: __|TX|__|TX|__|TX|__ > In my test the oscilloscope shows: __|TX|TX|TX|TX|TX|__ > > Also the wake up period is too short for a BoX-MAC-2: > http://tinyurl.com/32c7c27 It is tricky. The wakeup period is currently set for 5 ms, but this is mainly because of the backoffs and the time it takes to turn on/off the radio. I do not know what the usual period of Box-MAC-2 is.
