Motorola Mc9500k Manual

							Chapter 7 Using Bluetooth
Introduction
Bluetooth-equipped devices can communicate without wires, using frequency-hopping spread spectrum (FHSS) 
radio frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical (ISM) band 
(802.15.1). Bluetooth wireless technology is specifically designed for short-range (30 feet/10 meters) 
communication and low power consumption. 
MC9500-Ks with Bluetooth capabilities can exchange information (e.g., files, appointments, and tasks) with other 
Bluetooth enabled devices such as phones, printers, access points, and other mobile computers. To use the 
MC9500-K as a modem, create a dial-up modem connection between a computer and MC9500-K.
The MC9500-K with Bluetooth technology uses either the StoneStreet Bluetooth stack or the Microsoft Bluetooth 
stack. To write an application that uses the StoneStreet One Bluetooth stack APIs, refer to the Enterprise Mobility 
Developer Kit (EMDK) Help.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used with 
Bluetooth voice. All devices in the piconet (Bluetooth network) must be AFH-capable in order for AFH to work. 
There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections and discoveries 
during critical 802.11b communications. AFH for Bluetooth consists of four main sections:
Channel Classification - A method of detecting an interference on a channel-by-channel basis, or pre-defined 
channel mask.
Link Management - Coordinates and distributes the AFH information to the rest of the Bluetooth network.
Hop Sequence Modification - Avoids interference by selectively reducing the number of hopping channels.
Channel Maintenance - A method for periodically re-evaluating the channels.
When AFH is enabled, the Bluetooth radio “hops around” (instead of through) the 802.11b high-rate channels. AFH 
coexistence allows Motorola mobile computers to operate in any infrastructure.

The Bluetooth radio in this MC9500-K operates as a Class 2 device power class. The maximum output power is 
2.5mW and the expected range is 32.8 feet (10 meters). A definition of ranges based on power class is difficult to 
obtain due to power and device differences, and whether one measures open space or closed office space. 
Security
The current Bluetooth specification defines security at the link level. Application-level security is not specified. This 
allows application developers to define security mechanisms tailored to their specific need. Link-level security 
occurs between devices, not users, while application-level security can be implemented on a per-user basis. The 
Bluetooth specification defines security algorithms and procedures needed to authenticate devices, and if needed, 
encrypt the data flowing on the link between the devices. Device authentication is a mandatory feature of Bluetooth 
while link encryption is optional.
Pairing of Bluetooth devices is accomplished by creating an initialization key that is used to authenticate the 
devices and create a link key for them. Entering a common PIN number in the devices being paired generates the 
initialization key. The PIN number is never sent over the air. By default, the Bluetooth stack responds with no key 
when a key is requested (it is up to user to respond to the key request event). Authentication of Bluetooth devices 
is based-upon a challenge-response transaction. Bluetooth allows for a PIN number or passkey that is used to 
create other 128-bit keys used for security and encryption. The encryption key is derived from the link key used to 
authenticate the pairing devices. Also worthy of note is the limited range and fast frequency hopping of the 
Bluetooth radios that makes long-distance eavesdropping difficult.
Recommendations are:
Perform pairing in a secure environment
Keep PIN codes private and dont store the PIN codes in the mobile computer
Implement application-level security.
The Microsoft stack supports Smart-pairing. For detailed information, refer to the Microsoft MSDN.
NOTEIt is not recommended to perform Bluetooth wireless technology inquiry when high rate 802.11b operation is 
required.

Bluetooth Configuration
By default, the MC9500-K is configured to using the StoneStreet One Bluetooth stack. Refer to the MC9500-K 
Mobile Computer Integrator Guide, Appendix B, for information on switching to the Microsoft Bluetooth stack.
If the MC9500-K is configured to use the StoneStreet One Bluetooth stack, the Bluetooth icon appears at the 
bottom right corner of the Today screen. If the Microsoft Bluetooth stack is configured, the Bluetooth icon does not 
appear.

Bluetooth Power States
Cold Boot
With StoneStreet One Bluetooth Stack
Performing a cold boot on the MC9500-K turns off Bluetooth after initialization (which takes a few moments). It is 
normal to see the Bluetooth icon appear and disappear, as well as a wait cursor, when initialization proceeds in all 
modes.
With Microsoft Bluetooth Stack
Performing a cold boot retain the state of the Bluetooth radio prior to the cold boot.
Warm Boot
With StoneStreet One Bluetooth Stack
Performing a warm boot on the MC9500-K turns off Bluetooth.
With Microsoft Bluetooth Stack
Performing a warm boot retain the state of the Bluetooth radio prior to the warm boot.
Suspend
When there is an active Bluetooth connection, the Bluetooth radio goes into low power mode maintaining the active 
connection. When there is no active connection, the Bluetooth radio turns off.

NOTEIf there is an active Bluetooth connection between the MC9500-K and another Bluetooth device, the 
MC9500-K will not timeout. However, if the user presses the Power button on the MC9500-K, the MC9500-K 
will suspend (except when on a call) and upon receiving data from a remote Bluetooth device, the MC9500-K 
will wake from suspend mode. For example, headset redial or Bluetooth scanner sending data to the 
MC9500-K.

Resume
When the MC9500-K resumes, Bluetooth turns on if it was on prior to suspend.
Using Microsoft Bluetooth Stack
The following sections provide information on using the Microsoft Bluetooth stack.
Turning the Bluetooth Radio Mode On and Off
Turn off the Bluetooth radio to save power or if entering an area with radio restrictions (e.g., an airplane). When the 
radio is off, other Bluetooth devices cannot see or connect to the MC9500-K. Turn on the Bluetooth radio to 
exchange information with other Bluetooth devices (within range). Communicate only with Bluetooth radios in close 
proximity. 
Enabling Bluetooth
To enable Bluetooth:
1.Ta p  Wireless Manager and then tap the Bluetooth bar or 
Ta p  Start > Setting > Connections > Bluetooth icon > Mode tab.

3.Ta p  ok.
Discovering Bluetooth Device(s)
The MC9500-K can receive information from discovered devices without bonding. However, once bonded, the 
MC9500-K and a bonded device exchange information automatically when you turn the Bluetooth radio on. See 
Bonding with Discovered Device(s) on page 7-34 for more information.
To find Bluetooth devices in the area:
1.Ensure that Bluetooth is enabled on both devices.
2.Ensure that the Bluetooth device to discover is in discoverable and connectable modes.
3.Ensure that the two devices are within 30 feet (10 meters) of one another.
4.Ta p  Start > Settings > Connections tab > Bluetooth icon > Devices tab.

You are prompted to enter a passcode. If the device has a specific passcode, enter it in the Passcode field and 
tap Next. If the device does not have a specific passcode, enter a passcode in the Passcode field and tap 
Next. The Bluetooth radio tries to connect with the device.
9.If you created a passcode, you will be prompted by the other device to enter the same passcode. Enter the 
created passcode to establish a paired connection. (If you entered a passcode from the device, you shouldn’t 
have to do anything on the other device.)
10.When the connection is complete, a list of matching and supported services on the device appears.
11 .Select the services you want to use and tap Finish. The services on the new devices have to be selected or 
else the pairing won’t include those services, even though the devices are paired. If services are not selected, 
you will be continually reprompted for the passcode from the device.
12.The device appears in the list on the main window.
After the passcodes have been accepted on both sides, you have a trusted (“paired”) connection.
