Track me WiFi
Track me WiFi is similar to the original mode as it also sends a message when the monitored object starts moving and also sends one when the movement stops and the device does not move for an adjustable time period. All mode-specific events are sent with 3 MAC addresses for better localisation precision.

Switching to mode, arming and disarming information:
Follow the Basic Operations With SimpleHw Devices guide, where you can also find information about LED behavior, relevant Sigfox messages and more.
Here’s what’s important for Track me WiFi messages:
To set this mode, the downlink needs to include this mode register setting: 0116
The uplink messages need to begin with the mode hex as the first byte: 16
When arming the device, you should see this message: 1610
When the device is armed, it should send you these two bytes: 1611
If you disarm the device via long press, you should receive this message: 1614
