Firmware Version

2.5.x

Description

Tested with: Heltec HT-CT62

If Power Saving is enable Telemetry reporting become unreliable. Often you only will 1 or 2 telemetry packets being send to the mesh and then it stops.

How to reproduce

1. Set CLIENT or ROUTER role
2. sds_secs=ONE_DAY, ls_secs=ONE_DAY,min_wake_secs=1
3. Reduce Telemetry broadcast interval to a "testable" number like 1800
4. Also activate Environmental Telemetry with a sensor

Result

You will see 1 or rarely 2 broadcasts. Then nothing.

Client/Router functionality works without issues.

Cross-check with disabling "Power Saving" fixes the issues.

Relevant log output

No response

The device does not wake up to send telemetry. If you set power savings mode on, the device is likely just asleep for those interval broadcasts

Hm.. could we introduce an additional, Light-Sleep surviving check if telemetry is due?

So if the Router or Client gets a LoRa interrupt - additionally send telemetry?

+1 on this

Telemetry should also wake from light sleep
