4 years ago Thanks for the report. I believe this is the race condition we found and fixed recently:
https://github.com/nymea/libnymea-networkmanager/pull/5
The fix is not released to stable yet. You can test if this fixes your issue by upgrading to the experimental silo. For that, add this line
deb http://ci-repo.nymea.io/experimental-silo buster rpi
to /etc/apt/sources.list.d/nymea.list and apt-get update and upgrade.
There appears to be a race condition On Pi Zero W and Buster.
If: There is a wifi network configured, but the device is moved to somewhere that the network is not available OR no network is configured (i.e. all the networks are deleted with nmcli), then the nymea-networkmanager doesn't recognize there's no network on startup. (everything with default configuration)
In this state, restarting the service after the service starts up during boot fixes it.
However it doesn't happen if the network is available but has the wrong password, in this situation it does work.
End result is after configuring BerryLan, wiping the network and testing it works fine, and then when deployed to the new location, BerryLan never advertises.
To solve this, I needed to delay the nymea-networkmanager.service startup with: ExecStartPre=/bin/sleep 60
Great product BTW
