Bluetooth® settings configuration

The following are the instructions on how to easily prepare a Bluetooth® Dongle connection to the FMB device. First, we need to configure FMB device Bluetooth® settings. These are the required steps:

  • Go to Bluetooth® section similarly to as shown in the figure to the right (position 1).
  • Turn on BT Radio by pressing Enable (visible) (position 2). "Local name" (position 3) will automatically be "FMB1YX_last 7 imei digits", you can leave it or type your own name.
  • Set Security Mode (position 4) to PIN only or None (you could select PIN + MAC list or MAC list only security mode but in this case you need to type external device MAC address in Authorized Devices MAC List (position 7).
  • Set connection mode to OBDII (position 5).
  • Set External Name as your Bluetooth® OBD II device name for proper device identification and connection to it. In this example the OBDII device name is "DONGLE", at least 2 characters are needed to recognize it and connect to it. For better and faster adapter identification in the network, you could enter a full device name. You could check your OBDII adapter Bluetooth® name by scanning nearby Bluetooth® devices using a mobile phone or a computer with a Bluetooth® adapter.
  • Go to OBD II in main menu and select priority and others parameters visible in the following figure.

  • Now you can disconnect FMB device from the configurator.
