KKM B1 0011-04¶

Description¶

3rd party hardware from KKM Smart Solutions. It has user replaceable CR2450 coin cell battery and will last up to 1.5 years on a single battery with default settings in unconnected mode. Programmed from factory with Meshtech firmware to work seamlessly and integrate fully in a Meshtech system. It has a push button for input and LED/sound indication to provide feedback.

The Bluetooth chipset is nRF52832 from Nordic Semiconductor.

• Firmware Model Number: 0x0011 (17)

• DFU Type: Nordic DFU (Secure)

• DFU Advertisement Name: DFU_0011:{MAC Address +1}

Normal operation procedure¶

Similar to all Meshtech trackers the KKM B1 0011-04 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 all LEDs.

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

Supported Device Modes¶

• Storage

• Unconnected

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.
