[Bug]: Using yaml file to configure "modemPreset" and "region" causes the settings not to be applied.

[Wireheadbe]

using meshtastic --host xxx.xxx.xxx.xxx --configure file.yaml

With the following lora config:

config:
  bluetooth:
    enabled: true
    fixedPin: 123456
  device:
    nodeInfoBroadcastSecs: 10800
    role: CLIENT
    serialEnabled: true
  display:
    screenOnSecs: 600
  lora:
    hopLimit: 20
    modemPreset: LONG_SLOW
    region: EU_433
    txPower: 20

.. the "modemPreset" and "region" do not get applied on a freshly "wiped and flashed" device.

Hardware: Heltec v3.1

Firmware: 2.3.7.30fbcab

Meshtastic Python API: 2.3.8

Doing it manually:

 meshtastic --host 192.168.201.42 --set lora.region EU_433
Connected to radio
Set lora.region to EU_433
Writing modified preferences to device

-> Works, But the device didn't reboot immediately. Only after executing it a second time. -> After reboot, the region is set. -> Not sure if this is purely a python issue, or firmware issue

Same thing for modem_preset - via config file: not applied. Trying manually seems to work.

Same issue for hopLimit, txPower,..

Also one observation, is that whenever these settings are applied: the reboot afterwards is hit-and-miss. I'm not sure if this is purely related to the Python API, or the firmware. I've seen e.g. https://github.com/meshtastic/python/issues/41 - also https://meshtastic.discourse.group/t/preferences-settings-sometimes-not-sticking-saving-cli-2-2-22-firmware-2-2-24-app-2-2-24/10560/2 seems relevant.

So it would seem it isn't rebooting reliably after the configure imports the yaml?

[Wireheadbe]

Correct - tested on 2 devices, with full erase + firmware load. But, when it does reboot - it doesn't update the settings.

[Wireheadbe]

https://github.com/meshtastic/python/issues/576 seems related.

[geoffreygarrett]

576 seems related.

I've since found a solution on my end for my requirements. Something worth noting is that if you are setting the channel_url in your config (as I was) it too has a lora_config protobuf contained within. Of the two observations I made in #576, this seems to be what caused the second. The first problem, related to the --host TCP interface is probably what you're dealing with (if your yaml is complete above, and didn't have the channel_url omitted for brevity).
