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.
Trace me WiFi SuperLocal
Hex value: 0x53
Use cases: Package tracing for postal services, tracing international 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.
Register (hex) | Default (hex) | Delta (hex) | Delta information |
Sleep time (0x04) | 1 minute (0x41) | 10 minutes (0x4A) | Sleep time prolonged |
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 |
0xC0 | Start of movement WiFi Precise | 1 | Accelerometer-based movement detection, sent with 5 MAC pointers and RSSI |
0xC1 | End of movement WiFi Precise | 2 | Arrival delay countdown expired, sent with 5 MAC pointers and RSSI |
0xC6 | Tracing tag WiFi Precise | 3 | Periodical event sent only while moving, sent with 5 MAC pointers and RSSI |
0xFC | MAC storage readout | No | 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.
Hex | Register name | Default value (hex) |
0x02 | Departure delay | 15 seconds (0x0F) |
0x03 | Arrival delay | 10 minutes (0x4A) |
0x04 | Sleep time | 1 minute (0x41) |
0x05 | Tracing interval | 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) |
0xFC | MAC storage eraser | No default value - After this register hex, you can send up to 7 MAC pointers (0x01-0x80) to the device and then the respective MACs will be deleted from the internal MAC storage |
0xFD | MAC storage reader | No default value - After this register hex, you can send up to 7 MAC pointers (0x01-0x80) to the device, the respective MACs will be uplinked as the same number of 0xFC events |
Similar modes:
Hex | Mode name | Description |

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
