Trace me WiFi SuperLocal
Trace me WiFi SuperLocal is similar to the original mode as it also sends messages while the object is moving and stops sending them when it’s still. While moving, it periodically sends a message (the period length is defined in the Tracing delay register) so you can trace the monitored object. No more messages are sent after a stop of movement is detected and reported. All mode-specific events are sent with up to 5 MAC pointers and the respective RSSI for very precise localization.

Registers relevant for this mode:
If you change the general sensitivity of the accelerometer and the magnetometer (0x11 and 0x19), the respective axis registers reset to 0 as the general settings replace them and vice versa.

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 Trace me WiFi Precise messages:
To set this mode, the downlink needs to include this mode register setting: 0153
The uplink messages need to begin with the mode hex as the first byte: 53
When arming the device, you should see this message: 5310
When the device is armed, it should send you these two bytes: 5311
If you disarm the device via the long press, you should receive this message: 5314
