- Thread-topic: Designing a communication protocol
Hi,
I need to develop a asynchronous serial communication protocol over Bluetooth BR/EDR v2.1, profile iAP.
I know the general issues such protocol should address namely Framing, Error Control, Flow Control.
An existing solution uses this framing scheme
STX MsgID Length [Message] Checksum ETX
My idea is to use the following simplified scheme
STX MsgID Length [Message]
- I have cancelled the ETX because STX flag and Length seem to be able to correctly identify the end of the frame
- I have also cancelled the Checksum basing on the assumption that the Bluetooth SPP already implements some Error Control mechanism
I’m wondering if my assumptions are correct.
Please, can you share your expertise or give suggestions about this ?
Regards,
Gabriele
