Minicom locked during configuration


What can i do? (RAK7243)

pi@rak-gateway:~ $ sudo minicom -D /dev/ttyAMA0 -b 115200
Device /dev/ttyAMA0 is locked.
pi@rak-gateway:~ $


after I deleted the file /var/lock/LCK…ttyAMA0, i was able to open minicom.
But there is no response on keyboard. Even CTRL A , Z, E did not help

I turned off LTE->auto connection under gateway-config and everything worked, but
after a crash the interface is always locked…

You can refer to the documentation to complete the operation, which states that you must ensure that LTE connecting is disable.
