Detailed Description

Is a profile for Serial via bluetooth (SPP/RFCOMM).

Uses the utBluetooth module to provide serial transfer over bluetooth. Can be used to either send commands to the device via bluetooth, or to send data out (e.g NMEA data).

Note

ALLOW_BTSERIAL_COMMANDS should be defined to allow bluetooth to be used for debugging

REMOVE_RFCOMM can be defined to remove the module at compile time.

Todo:

An elegant way of disconnecting rather than typing 'no carrier' into a terminal

Function Documentation

BT_RFCOMM_On()

bool BT_RFCOMM_On

(

void

)

Returns the on/off status of the module

Parameters

void

Returns

bool - ON (true) or OFF (false)

Note
