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
