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.

For more information on what uplink messages (mode-independent events) and additional data from various sensors in the device (appended payload) can be sent regardless of mode and how to fine-tune message behavior (alerts), see Mode-independent information and events.


Event name


Event information


Start of movement WiFi Precise


Accelerometer-based movement detection, sent with 5 MAC pointers and RSSI


End of movement WiFi Precise


Arrival delay countdown expired, sent with 5 MAC pointers and RSSI


Tracing tag WiFi Precise


Periodical event sent only while moving, sent with 5 MAC pointers and RSSI


MAC storage readout


One pointer and its assigned MAC address sent

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
