10 How to communicate with PDA?
Firstly you need to set parameter of PDA and adapter and to make sure it must be the mode
of one master and one slave. What need to be paid attention is the port setting of PDA.
Taking WIN CE as an example, Bluetooth serial port settings are divided into the two
serial ports: push and pop, if the module connects with the mobile phone as a master
device initiatively, use the push port; If the module is connected by the mobile phone as a
slave device initiatively, then use the pop port.
11 How to communicate with Bluetooth mobile phone?
The general Bluetooth mobile phone can not connect the serial service of other Bluetooth
devices initiatively because they do not have serial service menu which can connect serial
port. If the user want to realize serial port connect between Bluetooth mobile phone and
adapter, they can set adapter as master device and connect Bluetooth mobile phone
initiatively. But if need data communicate with adapter module, the user need to write by
themselves generally or ask for serial communication software, which can be used on
mobile phone, from mobile phone producer.
12. Appendix
12.1 Equipment Type Number
The Class of Device/Service (CoD) field has a variable format. The format is indicated using the
'Format Type field' within the CoD. The length of the Format Type field is variable and ends with two
bits different from '11'. The version field starts at the least significant bit of the CoD and may extend
upwards.
In the 'format #1' of the CoD (Format Type field = 00), 11 bits are assigned as a bit-mask (multiple
bits can be set) each bit corresponding to a high level generic category of service class. Currently 7
categories are defined. These are primarily of a 'public service' nature. The remaining 11 bits are used to
indicate device type category and other device-specific characteristics.
Any reserved but otherwise unassigned bits, such as in the Major Service Class field, should be set
to 0.
