General functionality

size

General functionality configures Bluetooth to work in slave mode. This mode allows any external device to connect to FMU130.
Parameter BT Radio allows enabling or disabling Bluetooth. There are three different settings:

  • Disabled – Bluetooth functionality will be disabled.
  • Enable (hidden) – Bluetooth functionality will be enabled, external devices will be able to connect to FMU130, but no devices will be able to detect it.
  • Enable (visible) – Bluetooth functionality will be enabled and any external device will be able to detect and connect to FMU130.

It is possible to configure the Local name of the device, as well as the Local PIN, which will be used when trying to pair with the FMU130 device. There are two different parameters:

  • Local Name parameter lets user declare a visible name of FMU130 to external devices.
  • Local PIN parameter lets user configure Bluetooth PIN of FMU130 device.

The FMU130 supports composed Bluetooth Local names, which allows the user to have a predefined number of IMEI digits at the end of the device name. The format of the composed Bluetooth name looks like this:

Device name + %imeiX

X - how many digits will be taken from IMEI to show in Local name, digits will be taken from the end of IMEI. Minimum value of X is 1 and the Maximum value is 15.

Example:
If the configured Local Name parameter is "FMU_120_%imei7" and the IMEI of the device is 352093089520901, name will be displayed as FMU_120_9520901 (whether "_LE" is added at the end depends on whether device supports BLE or not. The full name of the device, which supports BLE would be FMU_120_9520901_LE).
If the Local Name is written incorrectly, the Bluetooth name of the device will be broadcasted as it is. An example can be seen below.

Example:
If the configured Local Name parameter is "FMU_120_%ime7" devices name will be broadcasted as FMU_120_%ime7 or if wrong X will be configured, for example "FMU_120_%imei20" devices name will broadcasted as FMU_120_%imei20.

FMU130 Bluetooth has several different Security Modes:

  • PIN only – only Local PIN will be reacquired to complete connection to FMU130.
  • PIN + MAC list – PIN and Authorized Devices MAC List will be checked against to allow connection to FMU130. If the external device MAC ID is in the list and correct Local PIN is entered then connection will be established, otherwise FMU130 will reject connection.
  • MAC list only – only Authorized Devices MAC List will be checked when trying to connect to FMU130. If external device MAC ID is in the list then connection will be established, otherwise FMU130 will reject connection.
  • None – neither Local PIN nor Authorized Device MAC List will be checked.

Auto Connect to External Device

Auto connection functionality configures FMU130 as master device, which allows connecting FMU130 to an external device. FMU130 currently supports these modes:

  • None – disables auto connection functionality.
  • Hands Free or OBDII – FMU130 starts searching for an external hands free headset. If FMU130 finds a device which matches user defined External MAC or External Name then FMU130 will try to pair with that external device. If the external device asks for PIN then FMU130 will send user defined External PIN. After successfully pairing FMU130 will connect to paired device.
  • Data Link – BT Data link mode is enabled by Configurator Data Link parameter: when Data Link is configured and FMU has a link with the server, paired device can send messages via Bluetooth SPP profile directly to the server. Messages will be encoded by codec12.

FMU130 can see up to 10 available devices. If there are more than 10 devices, the list may change with each new scan.

External Name parameter works as a substring, which allows user to enter a part of the full external device name. For example, if external device name is "HandsFreeHeadset" and user enters "HandsFree" in External Name parameter window, then FMU130 will be allowed to connect to an external device named "HandsFreeHeadset".
