I have a RUT240 on the latest firmware. I have a use case where the router is mounted in a pelicase with an external 4g/ wifi combo antenna and internal battery supply. The case will remain locked and an external power switch and socket installed.
I already have the LTE status visible on the logon page but for simplicity I would like to have a LED on the exterior of the case to indicate then the router has connected to the Mobile phone network. I am not bothered about signal strength I can get that from the login page if need.
I'm not a coder so, is there a janet and john way I can get the digital output to chnge state once the router has established a cellular connection?
