bsturgess commented 4 years ago

Hello

I have tried compiling this demo on both the online IDE and Mbed Studio and I get current consumption of 900ua after calling _ble.init

from the look of the cpu stats it is just never deep sleeping

Uptime: 2001 Sleep time: 1930 Deep Sleep: 0 Uptime: 4001 Sleep time: 3864 Deep Sleep: 0 Uptime: 6001 Sleep time: 5798 Deep Sleep: 0 Uptime: 8001 Sleep time: 7733 Deep Sleep: 0 Uptime: 10001 Sleep time: 9667 Deep Sleep: 0 Uptime: 12001 Sleep time: 11601 Deep Sleep: 0 Uptime: 14001 Sleep time: 13535 Deep Sleep: 0

Any ideas?
