Expected behavior

Since v1.3 pre-configuring Thread network parameters does not work anymore. I tracked it down to this commit.

Actual behavior (suspected bug)

If no data is found in NVS it should use the OPENTHREAD_NETWORK_xx configuration to create/join a thread network.

Error logs or terminal output

Steps to reproduce the behavior

Configure OPENTHREAD_NETWORK_xx parameters
Erase the board
Flash the board

Project release version

Additional context

as esp_openthread_auto_start is never called with NULL anymore, the config values are ignored.

Hi, thanks for reporting this issue. We have discussed for removing the pre-configured thread network parameters a lot before we published the TBR release v1.3. This feature designed for internal testing at the beginning. We thought there might be no users who would use this feature. So we changed to use the random network credential and added a change in the release notes.

Anyway, if you want to use this feature, you can add a workaround on your side to pass NULL to the function esp_openthread_auto_start. We will add a configuration later to set if the pre-configured or random thread network parameters will be used.

I was also trying to figure out why my preconfigured thread network wasn't working.
It would be great if we could input the Thread TLV, it would be a lot easier.
