BlueUp SafeX 0060
Description
3rd party hardware from BlueUp. See SafeX BLE for hardware details. It has user replaceable CR2477 coin cell battery. Will last up to 3 years on a single battery with default settings in unconnected mode. Delivered with Meshtech firmware to work seamlessly and integrate fully in a Meshtech system. It has a push button for input and vibrate/LED/sound indication to provide feedback.
The Bluetooth chipset is nRF52832 from Nordic Semiconductor.
- Firmware Model Number: 0x0060 (96)
- DFU Type: BLE SMP
Normal operation procedure
Similar to all Meshtech trackers the BlueUp SafeX 0060 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 both orange and red LED.
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.
Supported Device Modes
- Storage
- Unconnected
Service Mode
Service Mode can be used to perform DFU upgrades and/or factory reset of a device when provisioning information (i.e. network key) is unknown/lost. To enter Service Mode, button need to be pressed while powering on device; in this device's case - while inserting the battery. Device being in Service Mode is indicated by LED blinking rapidly. Device is discoverable by "SM" device name while in Service Mode. It runs BLE SMP and can be connected to and upgraded. To perform factory reset, press button continuously for more than 5 seconds while device is in Service Mode. LED will light constant while button is held, and should be held until LED turn off (5s) to perform factory reset. If no connection is established or no factory reset command is received, device will reboot and start in previous mode after 2 minute timeout. Timeout is extended while BLE connection is established and for additional 2 minutes after disconnect.

Current consumption
Average current consumption measurements done in some typical different device states. This is to illustrate that different advertisement intervals and SOS/Alarm active will impact battery lifetime significantly.
| Device state | Advertisement interval | Avg. power consumption µA | estimated years max |
|---|---|---|---|
| Storage sleep | NA | 0.9 | |
| Normal | 1000ms | 36 | 3.1 |
| Normal sleep | 3000ms | 23 | 4.9 |
| Alarm | 250ms + LED | 237 | 0.48 |
| Priority | 500ms | 55 | 2.07 |
