High Power Consumption in Deep Sleep #27
Description
Hi all!
I am building a simple water sensor that reads a water level from a touch PIN, packs the result into a BLEAdvertisement and goes into deep sleep.
However, during deep sleep the consumption is at 90mA which is way to high.
Without the bthome.begin(DEVICE_NAME, false, "", false); call, I am at 10.5 mA consumption in deep sleep, so initializing the BLE device seems to be the issue.
I already tried a few things to disable BLE before going to deep sleep (see below), but nothing seems to work. Any ideas?
