I have an application whereby i need to communicate with a Bluetooth device using the RFCOMM protocol. I'm not that familiar with bluetooth or its profiles! My question is if i use a bluetooth module with the Serial Port Profile firmware, does that mean i will have access to the RFCOMM protocol layer?
For implement SPP You must have RFCOM implemented before. More information in SIG documentation.
Actually I am develop one application with TI microcontroller and Bluetooth serial module (This module not have any facilites, I start my program writing hci transport protocol, next others protocols)...
For physical transport between the microcontroller and bt module, I use TTL low voltage UART @ 115200bps.
The best solution are usb(in case of PC, because the PC UART are speed limitation), but for general purpose, serial solution are more easy for development and evaluation.
