Xiamen-lenz protocol

Integration level: params + settings
Protocol used by GPS and MDVR devices manufactured by Xiamen Lenz headquartered in China.
flespi parses the Xiamen-lenz protocol messages into a JSON object with the fields listed below in the Parameters tab.

To connect your tracker using the Xiamen Lenz protocol, you need to have a xiamen-lenz 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.

It is possible to configure Xiamen Lenz devices OTA using the flespi web-based configurator tool. To connect Xiamen Lenz to Wialon or another platform via flespi please read this article.
