Why was it working in the past but not working now?

may be need updated FW? what do you think?

I don’t know, you can try different firmware

can i have the links of the latest FW?

How about this?

https://source.sierrawireless.com/resources/airprime/software/wp77xx/wp77xx-firmware-release-15,-d-,1/

i tried few of them…now i am not getting legato status !!! legato is not running !!!

How about start it by “legato start”

getting error

no idea why your module suddenly has problem…

see if downloading and performning recovery mode can help

FW is updated and it works now…dont know why it happened !!!

I have another issue with “gpsAPP”

where “map locate” in not giving output once we run the “gpsApp”.

it says a note that where we are using wp77

Have you tried with wp76 then?
Have you tried with at!GPSFIX command first?
Or you can simply use gnss command
