Trace me WiFi

Trace me WiFi 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 stop of movement is detected and reported. All mode-specific events are sent with 3 MAC addresses for better localisation precision.

Trace me WiFi

Hex value: 0x17

Use cases: Package tracing for postal services, tracing trucks, river transport boats and more

Devices that support this mode: SimplePack Plus

Required sensors: Accelerometer, WiFi module

Mode-specific deltas:

Deltas are mode-specific register values different from register default values.

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.

Similar modes:

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 messages:

To set this mode, the downlink needs to include this mode register setting: 0117
The uplink messages need to begin with the mode hex as the first byte: 17
When arming the device, you should see this message: 1710
When the device is armed, it should send you these two bytes: 1711
If you disarm the device via long press, you should receive this message: 1714
