Hi, Thanks!
I reckon you can use
NRF.sleep()andNRF.wake()to stop advertisements. However that will make the device unconnectable when it's not advertising.Also you really want to let it send quite a few advertisements (so leave make 2 seconds between
wakeandsleep). It's radio so there's absolutely no guarantee that a single message will get through to the Pi.I wouldn't be too worried about the battery usage of advertising though - it's not that huge. You can always reduce the advertising interval to once a second or so, which will really reduce the battery usage without you having to do anything painful with
wakeandsleep.
