Please contact ZBA for details on purchasing a development board to interface the module
to the PC.
Microcontroller Interface: The UART of the Bluetooth module can directly connect to the
microprocessors UART. The Microprocessor must have an I/O that will operate from 0 to
3.3 Volts or the appropriate level shifter circuitry must be used as to not overstress the I/O
of either device.
Please note. The modules will only response the host set-up commands after the module has
entered the command mode. For module to enter in the command mode, the host must send
a single character
ESC <0x1b>
within 5 second after the unit has been powered on. If the
ESC
character is not sent within the specified 5 second window then the module will
automatically enter the SPP mode and any information sent to the UART will be treated as
data to be transmitted over a Bluetooth link.
Note:
All Commands except the first <ESC> command contain a suffix of <CR><LF>.
