I'm use a microcontroller + CSR bluecore 3 gateway to made a Bluetooth
device.

I have some question for Bluecore-3-Gateway SPP mode, Please give me
some help.

My question is below, I can use the AT command to control module
process pairing and connection,

And via the SPP mode transmit stream data, but I can't disconnect in
the stream mode,

because the module consider the AT command(AT+CRDR) is stream data
too.

Please answer me, How to disconnect in the stream mode, and bluecore 3
have any at command of escape sequence.

Thanks in Advance.
