Hello, thank you. I have this one:
When I send the commsnd AT it responds with OK.
But in general, when I disconnect the Pi Zero from the WLAN, does it automatically switch to the HAT?
I want to send a picture per email with a phyton script. With the WLAN it works fine, but when I switch off the WLAN, nothing happens. It does not use the HAT. It is not that simple, isn't it?
