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.

Mode-specific events (uplink messages):

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.

Registers relevant for this mode:

If you change the general sensitivity of the accelerometer and the magnetometer (0x11 and 0x19), 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 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
