Auto Master (SM,3<CR>)
In this mode, the FireFly makes connections automatically on powerup, and
re-connects when connection is lost. This
high speed connect mode, and cannot be broken by software break characters.
In all master modes the device will not be discoverable or allow configuration remotely over
Bluetooth.

NOTE: The RS422 interface uses the MAX490 transceiver. This device is designed to operate with input voltage
range of 4.75 to 5.25 VDC.
RXD+ and TXD+ each have a 4.7K pull up to 5VDC.
RXD- and TXD- each have a 4.7K pull down to GND.
NOTE: The RS232 interface uses the SIPEX SP3232ECA chip with capacitor switch to generate the + and

.
Device Configuration
The default configuration for the FireFly is
•
Bluetooth slave mode
•
Bluetooth pin code 1234
•
Serial port 115K baud rate, 8 bits, NP, 1 stop bit
•
Serial port flow control disabled
•
Low power mode off
Configuration is done by putting the FireFly into command mode and sending ASC
over the serial port or over the Bluetooth link.
Once you change the configuration parameters, they persist until changed or a factory reset is performed.
