- 44 - CalAmp Proprietary & Confidential

The LMU-4100™ supports Bluetooth functionality using the CalAmp Bluetooth Adapter

(BTA) (Part Number TC1106-9). The LMU-4100™ can be configured to use the BTA as its

Host port able to either initiate or accept the Bluetooth connection to the other device(s).

Using the CalAmp Bluetooth Adapter

(BTA)

The Bluetooth adapter has three parameters associated with it.

• Parameter 2080 – Bluetooth Name:

This Parameter contains a string which is compared to the remote device names

during a scan. If this string is found within the name of a remote device the BTA

will attempt to connect to that device. If this string is empty, all remote device

names will be eligible for connection.

• Parameter 2081 – Bluetooth PIN:

The PIN is effectively the password one Bluetooth device uses to access another.

When the LMU-4100™ initiates the connection, this should be the PIN of the

remote device. When the LMU-4100™ is accepting the connection, this is the value

the connecting device should use.

• S-Register 170 – BlueLocator Configuration Settings:

This is another bit mapped S-Register with the following controls:

o Mode Control (bits 0 and 1)

The BTA supports two modes, Off, and Host Port. A value of 0 is off, and a

value of 1 sets the BTA up as a Host Port. 2 and 3 are not defined and

should never be used.

o Discoverable (bit 2)

Discoverable means that the LMU-4100™ will be visible to other Bluetooth

devices when they perform a scan. Setting bit 2 enables discovery, clearing it

disables discovery.

o Initiator/Acceptor (bit 3)

This function controls if the LMU-4100™ will attempt the Bluetooth

connection (Initiator) or if it will wait for a device to connect to it

(Acceptor). If bit 3 is set, the LMU-4100™ will act as an initiator, if it is

cleared, the LMU-4100 will act as an acceptor.

o Profile (bit 4)

The BTA supports two Bluetooth profiles, the Serial Port Profile or the Dial-

Up Networking profile. This setting applies to both the host port and

modem port modes.

o Security Mode (bit 5)

The BTA supports a high and low security mode. In the high security mode,

the connecting device must supply the PIN every time it connects to the

BTA. In low security mode, it is only provided on the initial connection.

If bit 4 is set, the LMU-4100™ will present the Dial

Up Networking Profile, if it is cleared, the LMU-4100™ will present the

Serial Port Profile.

For older versions of the Bluetooth Adapter, this setting only applied when the BTA was acting as the

modem port.
