> The timing for this is deliberately set to be very conservative in terms of the wakeup window (at the cost of higher power) Yes, the minimum interval of when to start listening is determined by both radios clock accuracy budget, one of which can be known and the other assumed. > so the radio is probably powered up for a good 5ms before the beacon arrives. No, not anywhere near that long. I don't have a board wired out for current measurements, but for reference, 5ms/101ms beacon with DTIM=1 would be a 5% duty cycle without any useful data, unacceptably high for many battery powered devices. |
