configurations

Bluetooth friendly name, etc.
• Supports security and bonding

• Adapter will be a serial port profile acceptor as default. It can be reprogrammed to be an
initiator but will require a specific BD address that it will connect with to be programmed
in.
• If the Adapter is in ‘imitator’ mode, it will be a Bluetooth Master device, and when it
connects to another device and that device requests a role reversal, the Adapter must accept
the reversal and become a slave. If the Adapter is in ‘acceptor’ mode, it will be a slave and
will not request any role reversal.
• Default baud rate 19,200
• Baud rates configurable from 9,600 – 230,000
