I am testing an EC25-AF for a project that has the module installed in mobile vehicle. Whenever the LTE connection is lost, it takes exactly 5 minutes for connectivity return. I am able to replicate the issue consistently. On the contrary, when testing with a USB modem stick, of a different manufacturer, the reconnection happens much quicker (seconds). Is there some configuration in the modem which could be delaying reconnections? Anything I can do to speed up reconnection when the modem encounters weak/no signal?
I am running latest firmware EC25AFFDR07A09M4G_01.005.01. Running on Raspberry Pi and QMI. This issue happened with previous firmware as well.
