The Queclink GL100 protocol

The protocol of Queclink's GL100 and GL100M, <strong>battery devices for assets and people</strong>: they are not wired into a vehicle, which is why they report far less often.

They are configured with commands. Their point is battery life: the device sleeps between reports, and that rate decides whether it lasts months or weeks.

Which port it comes in onOur server listens for the Queclink GL100 protocol on port 6003. That is the port you set on the device, together with the server address. Point it somewhere else and the data still leaves, but the server cannot read it.
Careful with what other sites tell youIt is a different family from the GL200 and from the GV, however similar the name looks. <strong>Three families from the same brand, three separate pages</strong>: confirm which one your part number speaks before registering a batch.

Build the configuration command

We do not have this protocol's commands yetWe would rather tell you than make them up. We only publish the ones we have checked against the manufacturer's manual or against a real device. If you have them confirmed, send them to us and we will add them.

Where the data comes fromPublic mobile TAC database (MIT licence, Copyright (c) 2026 Moaz Ebrahem), TAC codes published by Teltonika on its official wiki, and the protocol observed on devices connected to the Appogio platform. We publish no full IMEI and no customer data.
