Serial Port Profile
When shipped with the on-board Serial Port Profile (SPP), the module’s firmware emulates
the function of a serial port. When connected to the host microprocessor via the UART
transport, the module appears as a COM port. This makes it easy for designers to write
software to utilize Bluetooth wireless communication. The SPP profile embedded
within
the module provides a menu for making configuration changes utilizing AT commands
described below in section 8.2:
8.1 Default Configuration
•
UART Baud Rate: 9600 baud
•
Number of Bits: 8
•
Stop bit: One
•
Parity: None
•
H/W Flow Control: Disable
•
PIN: 1111
•
Device Name: ZBA-SPP
•
Mode: Slave
•
Sleep Mode: Deep sleep when ever possible.
•
Partner pairing is dropped at power off or un-pairing by master.
8.2 Configuration Command Set-up & Procedures
PC interface: If you wish to connect the module to a PC’s comm. port it is necessary to
include a level shifter between the module and the PC. A recommended interface IC would
be the MAX3232 RS232 driver IC (or equiv.) and a 3.3 Volt voltage regulator.
