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.

Track me WiFi

Hex value: 0x16

Use cases: Tracking luggage, parcels, containers etc.

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.

Register (hex)	Default (hex)	Delta (hex)	Delta information
Sleep time (0x04)	1 minute (0x41)	0 (0x00)	Sleep time turned off

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.

Hex	Event name	Alert	Event information
8C	Start of movement with WiFi 1/2	1	Accelerometer-based movement detection, sent with 3 MAC addresses
8D	Start of movement with WiFi 2/2	1
8E	Stop of movement with WiFi 1/2	2	Arrival delay countdown expired, no movement detected anymore, sent with 3 MAC addresses
8F	Stop of movement with WiFi 2/2	2

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.

Hex	Register name	Default value (hex)
0x02	Departure delay	15 seconds (0x0F)
0x03	Arrival delay	10 minutes (0x4A)
0x11	Accelerometer sensitivity	7 (0x07)
0x12	Accelerometer X axis sensitivity	7 (0x07)
0x13	Accelerometer Y axis sensitivity	7 (0x07)
0x14	Accelerometer Z axis sensitivity	7 (0x07)
0x3C	Accelerometer measurement period	1 second (0x01)
0x49	Accelerometer detection delay	0 seconds (0x00)

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
