Hi, Sorry for being ignorant (as I can't quite find the filter duplicate code other than the setting of the bit), but would throttling work here? Cap the duplicates at say every 100ms or 10x/second. That probably won't help with power consumption (unless start/stop of the radio is quick?). Just trying to help move this along.. willing to code/test.
