KKM W8U 0061¶

Description¶

3rd party hardware from KKM Smart Solutions. See Medical Wristband W8 for hardware details. It has user replaceable CR2032 coin cell battery. Will last up to 1 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 LED indication to provide feedback.

The Bluetooth chipset is nRF52832 from Nordic Semiconductor.

• Firmware Model Number: 0x0061 (97)

• DFU Type: BLE SMP

Normal operation procedure¶

Similar to all Meshtech trackers the KKM W8U 0061 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 provisioned by command via system/gateway. If no provision command 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 red LED.

In unconnected mode device will advertise tracking and status updates. Alarm is activated by pressing button 1s and both LED blink. Red LED will continue to blink periodically as long as alarm is active. Alarm state can be confirmed/cleared from system.

Alarm can be manually deactivated by “OSO” button sequence when operating in alarm-mode 1 (default).

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.
