+    By default the synchronization between the BLE framework and Berry happens every 50 milliseconds, which should be enough for the majority of use cases. For very fast BLE devices it can be necessary to use Berrys `fast_loop` to trigger this at maximum speed (of about every 5 milliseconds). This is typically done in an init function of a class like that:
+    `tasmota.add_fast_loop(/-> BLE.loop())`
