I have an EP06-E LTE-A module paired with OpenWRT (R00ter to be specific). Whenever doing reboots, it was noticeable that the module won't accept AT commands unless this process "uqmi -s -d /dev/cdc-wdm0 --wda-get-data-format" is manually terminated then everything will proceed fine.
Done a couple of re-installation but still no luck. Is there any workaround with this?
Not sure why is this happening. Hoping someone could put light on this issue.
