BLE issues with v9.08

[leo-b]

PROBLEM DESCRIPTION

I upgraded to from 9.07 to 9.08 yesterday. Since then I am noticing much more frequent watchdog reboots.

The first watchdog reboot after the update happened after 18 hours but after that, the restarts occured more often:

Besides my ping monitor reports regular packet losses (every 5 to 10 minutes), I suppose because of hanging tasks?

Why do you have Nuki debug logging enabled?

This is almost guaranteed to give issues on its own on an ESP32 without PSRAM, especially while also having MQTT logging enabled.
This will in its own cause unnecessary stress on the BLE and MQTT client that is not meant for production devices.
These options are only for development and advanced debugging and only when asked to enable these settings by a developer.

Please disable all debug logging and observe if you have issues afterwards.
If so provide your info page with these settings disabled and information about what watchdogs triggers and other restartreasons you observe.

Why do you have Nuki debug logging enabled?

Because you told me to do so in order to find out the reason for the daily watchdog restarts:
#547 (comment)

The regular watchdogs resets are still present, that's why I am still reporting the issues in #547.

This is almost guaranteed to give issues on its own on an ESP32 without PSRAM, especially while also having MQTT logging enabled.

Debug logging via syslog (UDP) would be a nice feature and much more convenient than MQTT logging.

It looks like the new version somehow triggered some instability in the nuki firmware.
After a lock-reboot with

mosquitto_pub -t 'nuki-garten/configuration/action' -m '{"rebootNuki":"1"}'

... the BLE connectivity issues are gone for now.
Let's see if they will reappear.
