Don’t drop me WiFi SuperLocal
Don’t drop me WiFi SuperLocal behaves similarly to Guard me WiFi SuperLocal (just like the original Don’t drop me is similar to Guard me) except for its event (uplink message) is triggered by a faster acceleration of the accelerometer in one of its axis and not just movement detection. Drop alert detection threshold can be defined and the mode-specific event is sent with up to 5 MAC pointers and the respective RSSI for very precise localization.
Don't drop me WiFi SuperLocal
Hex value: 0x54
Use cases: Monitoring packages inside trucks, shipping containers, and more
Devices that support this mode: SimplePack Plus
Required sensors: Accelerometer, WiFi module
Mode-specific deltas: None
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 |
0xC7 | Drop alert WiFi precise | 3 | Sends a message when dropped - high acceleration, 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) |
0x15 | Drop me threshold | 936 mG (0x60) |
0x16 | Drop me duration | 200 ms (0x02) |
0x17 | Drop me axis configuration | 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 MAC addresses 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 MAC addresses will be uplinked as the same number of 0xFC events |

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 Don’t drop me WiFi Precise messages:
To set this mode, the downlink needs to include this mode register setting: 0154
The uplink messages need to begin with the mode hex as the first byte: 54
When arming the device, you should see this message: 5410
When the device is armed, it should send you these two bytes: 5411
If you disarm the device via the long press, you should receive this message: 5414
