MQTT KeepAlive setting

[speckenbuettel]

Hi,

I don't see a setting for KeepAlive in OpenDTU. Is there no possibility to adjust this?

Standard setting seems to be 15 s, which leads to frequent connections and disconnections from my MQTT broker (Mosquitto2):

2025-08-21T03:34:10UTC: New client connected from 192.168.188.163:65250 as opendtu (p2, c1, k15, u'opendtu').
2025-08-21T03:34:00UTC: Client opendtu has exceeded timeout, disconnecting.
2025-08-21T03:25:35UTC: New client connected from 192.168.188.163:65249 as opendtu (p2, c1, k15, u'opendtu').
2025-08-21T03:25:19UTC: Client opendtu has exceeded timeout, disconnecting.

I think it would be helpful to adjust KeepAlive to 60 s, as I have it for most other MQTT clients.

Thanks and best regards,
Falk
