NBL-2

Introduction to the product

Description:

Netronix NBL-2 -  wireless RFID reader with Bluetooth.

NBL-2 is great in these use cases:

• Authorized driving - keep track of who is driving your vehicle according to the NBL-2 ID they use to authenticate themselves.
• Private mode – gives the ability to mask all the personal data while the vehicle is used in Private mode.

Functionality:

• Unpaired reader (state after default reset) is waiting for button only
• Reader scans for RFID card or button press all time after it is paired
• In the case previously mentioned events occur, the reader sends an advertising packet for Ta time in period Tb. Defaults: Ta=50sec, Tb=100ms
• While NBL-2 is advertising the green led is flashing slowly. The reader stops blinking and advertising after disconnection.
• Depending on the configuration, read card ID can be present on the advertising packet or/and on characteristic
• Reader closes the connection and goes into low power 50 seconds after the last data exchange.
• Each LED can be controlled on GATT services
• Reader can be on/off by long button press
• Reader performs sensor measurement in a period that is configurable
• Button reacts immediately
• Sensors configuration is set by GATT services.
• Detecting the start and stop of the vehicle. This mode is active immediately after turning on the device.

NBL-2 configuration

1.    Updating NBL-2

First, you have to make sure that NBL-2 firmware version is updated to 1.3. Go to NBL Tools application -> Device -> Characteristic -> Device Information Service -> Firmware Revision String.

Note: If the firmware version is 1.1 or 1.0, it is not possible to update it.

If it is 1.2, then update NBL-2 according to these steps:

1.      Run the NBL Tools application

2.      Update the firmware database (tap: Manager Firmware -> Update the database -> Start). Select NBL-2 and check 1.3 firmware version.

3.      Back to the main menu.

4.      Tap the Device option.

5.      Wake up the device - eg entering it into the bootloader mode.

6.      Select the device from the list (long press), then select Update firmware from the drop-down menu and press the Start button.

7.      Correct firmware update will be signaled by device start-up led message.

Device configuration

Setting up NBL-2 device to connect with FMB device. Go to Teltonika configurator -> Bluetooth 4.0 and set it up like it shown in this screenshot (MAC address will depend on your particular NBL sensor):

Mandatory setting condition: Non Stop Scan

Then go to I/O settings:

Make sure to enable BLE RFID #1 parameter (ID: 51740) and set the operand to „On Change“.

Setting up Private/Business mode

Make sure to enable Private/Business mode in Trip/Odometer settings. It can be done using SMS commands or a configurator. Not every device has these parameters visible in the configurator, therefore they should be configured via SMS commands. It can be done by sending  setparam SMS (how to send SMS commands: https://wiki.teltonika-gps.com/view/FMB120_SMS/GPRS_Commands). Set it to High or Low priority (parameter ID: 11850). Enable triggers as NBL-1 Button1 or NBL-1 Button2 (parameter ID: 11811).

Don't forget to set up data masking in Private mode if necessary.

Don‘t forget to save all these changes to the device and you are ready to test the NBL-2 sensor.

More information about Private/Business Driving Mode Functionality.

Testing NBL-2

Power up the FMB device and start logging it into the Terminal application. When the RFID card is not enabled, the BLE RFID #1 parameter (AVL ID: 451) will show a specific value. Example:

IO ID[451]: 0x0000000000000000

When the RFID card is activated (card touched to NBL-2 and followed by two beeps) BLE RFID #1 parameter should look like this:

IO ID[451]: 0x0004193EF2576680

When Private/Business mode is enabled (Button1 or Button2 is pressed):

IO ID[451]: 0x0000000000000000

and

IO ID[391]: 1

NBL-2 packet

NBL-T data is being read via broadcast packets only. The packet structure is described below:
