Protocol used by MDVR devices manufactured by Howen headquartered in China.
flespi parses the Howen protocol messages into a JSON object with the
fields listed below in the Parameters tab.
To connect your tracker using the Howen protocol, you need to have a howen channel created first.
Point your MDVR 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 Logs & Messages tab on the device screen to check if the messages are coming.
It is possible to configure Howen devices OTA using the flespi web-based configurator tool. To connect Howen to Wialon or another platform via flespi please read this article.
