  • DFU Type: Nordic DFU (Secure)
  • DFU Advertisement Name: DFU_0011:{MAC Address +1}

Normal operation procedure

Similar to all Meshtech trackers the BlueUp SafeX BLE 0011-01 is delivered in storage mode. This is to conserve power and avoid BLE advertising during transport. Normal operation device-mode for this device is unconnected. Pressing button for 1s will make device discoverable by advertising BLE storage mode advertisements, and device can be switched to unconnected mode by command via system/gateway. If no command to switch device mode is received while being in this state, device will go back to sleep and stop advertisements. To simplify provisioning to unconnected mode, pressing button for more than 5 seconds while in storage mode will automatically switch it to unconnected mode, and no command to switch mode is necessary from the system. When activating by long press, device will indicate that long press (5s+) has been received by lighting orange LED and vibrating.

In unconnected mode device will advertise tracking and status updates. Alarm is activated by pressing button until device vibrate and blink orange LED 3 times. Orange LED will continue to blink periodically as long as alarm is active. Alarm state can be confirmed/cleared from system, and device will indicate with red LED and vibrate to show that alarm has been cleared.

Supported Device Modes

  • Storage
  • Unconnected
  • DFU


In DFU mode, the device MAC Address will increase with one. As an example, if MAC Address is AA:BB:CC:11:22:33, in DFU mode device will appear with MAC Address AA:BB:CC:11:22:34 and advertisement name "DFU_0011:AABBCC112234". Another example if MAC Address is AA:BB:CC:11:22:3F, in DFU mode device will appear with MAC Address AA:BB:CC:11:22:40 and advertisement name "DFU_0011:AABBCC112240"
