Re: Check network on boot via rc.local

your while loop does nothing here as I suppose that sleep sets the default return code ($?) to 0 ...
if you want to wait for the network put the ping in the loop.
But as was said, the network is not up yet in rc.local and you should look into SystemD

Re: Crontab Issue with Paho MQTT

Usually, the problem is that the network is not completely up and running when you script executes.
The easiest way around I've found is to add a sleep for a few seconds before connecting to the MQTT server (I know it's not "nice" nut it works)

That's great, Thanks to the team.
Do you think the Bluetooth chip will be able to handle HFP connections ? it looks like it is not possible on 3B.
