Hey,
I’m trying to connect my raspberry pi to LTE using a Sixfab LTE Base Hat and a EP06-E.
I tried this two ways:
In both cases I can establish a connection, but after the first HTTP request or several pings the connection breaks.
See the logs from the connection using the first approach “QMI Interface Internet Connection”
