Hi everyone,
I'm trying to repurpose a 2-year-old Queclink GB100 GPS tracker that was previously tied to a fleet subscription.
I removed the PIN code from a personal SIM card and inserted it, but the red, blue, and green LEDs just flash rapidly (about once a second). It seems stuck searching for a network and won't connect.
I could really use some advice on a few things:
Network connection: How do I get it to connect to the GSM network? Could it be network-locked, or does it just need the correct APN settings?
SMS Configuration: I know these are configured via SMS commands, but since it's not getting online, I can't reach it. Is there a way to bypass or reset the password/configuration?
Hardware pins: There are 7 pins on the back (* * * * / * * *). Is this a serial/UART interface that I can use for direct configuration via cable?
How do I move on from here? Any insights or command guides for the GB100 would be awesome.
Thanks in advance!
