63H (Wi-Fi Geofence Notification)¶
When the terminal enters/exits the signal coverage area of the specified Wi-Fi hotspot, the terminal will generate and send this message to the backend server. For the Wi-Fi Geofence function, please refer to the AT@WIFIGEO command.
The frame format of a report that only carries 63H record is as follows:
For example (Total 37 bytes):
2B 00 00 25 00 01 23 45 67 89 01 23 45 C0 31 00 0A 00 00 0E 66 8E 47 F7 00 00 63 01 80 9A 02 01 00 01 23 C0 24
