OpenWRT + EP06-E

Hi Everyone,

I have an EP06-E LTE-A module paired with OpenWRT. 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.

Both issue persist to a vanilla OpenWRT as well as R00ter. This seems to be a timing issue. I have to kill all " uqmi " processes before the next commands in the script to execute.

sleep 3
killall uqmi

script locations:

Vanilla OpenWRT --> //
R00ter OpenWRT --> /usr/lib/rooter/qmi/

Yes. Many thanks for the tip!
