Tkstar protocol

Protocol used by GPS tracking devices manufactured by TKSTAR headquartered in China.
flespi parses the Tkstar protocol messages into a JSON object with the fields listed below in the Parameters tab.

To connect your tracker using the TK-Star protocol, you need to have a tkstar channel created in your flespi account.

You can register free flespi.io account in few clicks and follow this guide to connect TK-Star device to your flespi account.

You have to point the tracker to the channel's IP:port via SMS or configuration utility provided by your vendor. You can directly use the domain name provided by the channel instead of IP or resolve it into the IP address using any resolving service in the Internet.

After correctly configuring the device to the address of your channel you may check the 'Logs & Messages' tab on the device or channel screen to validate if the messages are coming or connection to your channel has been established. Ensure that device can lock satellites to catch current time and position for the very first message.
