What is the minimum and maximum values I can set for
BLE.setScanTimeout(100);
Currently I have set it for 1 sec and want to reduce it to 0.5 sec. Will it affect the battery more since I am using battery to power Argon.

The unit for BLE.setScanTimeout()
is 10 millisecond units. The minimum value is 1 (10 milliseconds or 0.01 seconds).
The maximum is BLE_GAP_SCAN_TIMEOUT_UNLIMITED
, which is a value of 0, and means scan forever, BLE.scan()
never returns. This should only be done from a worker thread, never from loop() or a software timer.
Scanning itself does not use significant battery power as it’s receiving. Though because devices only advertise at a set interval, very short scan intervals are likely to miss advertisements. A half second (50) should be fine.
