Hardware

Heltec V3

Firmware Version

2.5.x

Description

If the device is set as CLIENT with power saving activated it stays awake the entire time.

How to reproduce

1. Set "CLIENT" role
2. Set "Minimum Wake Interval" to 1s
3. Look at the console

It stays awake the entire time:

DEBUG | ??:??:?? 662 [Power] Battery: usbPower=0, isCharging=0, batMv=4122, batPct=95
DEBUG | ??:??:?? 682 [Power] Battery: usbPower=0, isCharging=0, batMv=4122, batPct=95
DEBUG | ??:??:?? 702 [Power] Battery: usbPower=0, isCharging=0, batMv=4122, batPct=95
DEBUG | ??:??:?? 722 [Power] Battery: usbPower=0, isCharging=0, batMv=4122, batPct=95

Compared to the ROUTER role:

INFO  | ??:??:?? 1 [RangeTestModule] Range Test Module - Disabled
DEBUG | ??:??:?? 4 [PowerFSM] Enter state: ON

screen_on_secs and wait_bluetooth_secs also delay Light Sleep

Can confirm. Reducing both to 1s fixed the issue. Device now properly sleeps in "CLIENT" role.

Thanks for super fast help.

No worries. The power FSM is a complex beast. Router mode cuts through some of the states adding to confusion. One of these days we'll do some cleanup and consolidation.
