MeiTrack P88L: Extending protocol to parse WiFi APs

fieldappguya year ago

Hi,

I am currently testing out the Meitrack P88L and it can send in up to 8 WiFi APs. In the protocol there only seems to be support for older GPS based trackers for vehicles, not personal trackers. Is it possible to extend this protocol somehow?

|First WiFi info:AE233FC0D496D2FF| - where the last four values are the RSSI, ie D2 - FF (little endian)

The message format I get from a P88L using there COM software tool (so already translated from hexadecimal):

Event code:Track By Time Interval|GPS positioning status:Invalid|
