Hi Robert,
There are a lot of messages from the commands you posted. I guess I have auto-start of ppp0. It failed and tried several times. So there are a lot of messages with 'grep wl | grep wlan0 ’
I believe it is caused by ppp0 failure during initialization. Our board has a separate power enabling circuit for cellular module. I am going to disable that to bring wifi up first.
Best Regards,
David
