We have a few MC7430 modules that we recently purchased to migrate from older 3G modules. These modules come from our supplier configured in a way that, when given power, they automatically start a data session without any PPP interface or QMI activity. This causes problems for us when it comes time for the embedded linux OS to make a QMI or AT connection. Sometimes this connection succeeds, and sometimes it results in repeated authentication attempts to the carrier without a data session starting.
I am trying to fault-find why this is, but for the time being I’d like to be able to disable this automatic connection behavior if possible. I’ve looked through the AT command reference, but I can’t find/don’t know what to look for regarding this function.
Is there any way to stop the MC7430 from establishing it’s own data connection before the machine behind it attempts the same?
Thanks for any assistance.
