I have an MC7511 in QMI mode managed by a python script on Linux using libqmi. It is connected to AT&T via an IPv4 PDP session. This is the router.
A WIndows 10 machine connects to the router above via WiFi. A hard crash occurs on the MC7511 when I join a Microsoft Teams call at the Windows 10 machine. By hard crash I mean that data flow immediately ceases at the MC7511 and /dev/ttyUSB2 is no longer responsive.
I’m still trying to characterize but so far this only happens with Microsoft Teams when joining a call. Teams otherwise works OK say for general chat.
I’m running the AT&T image below which is latest. Anyone seen something like this?
