Protocol used by GPS tracking devices manufactured by several manufacturers, but primarily by cGuard headquartered in Russia.
flespi parses the Cguard protocol messages into a JSON object with the
fields listed below in the Parameters tab.
This protocol is used by all cGuard GPS tracking devices and by other tracker manufacturers (e.g. Italon and Agent GPS).
To connect your tracker using the cGuard protocol, you need to have a cguard channel created first.
Point your tracker to the channel's domain name:port via SMS or configuration tool provided by the vendor.
Then create a device instance for your tracker and use a 15-character IMEI (usually specified on the tracker casing) in the ident field.
Use the Toolbox tab on the device screen to check if the messages are coming.
