How can I get the maximum throughput out of a BT7xx?

Answer

Configuring the BT7xx as below should provide maximum throughput. AT&F* - erases the modules current settings ATZ ? resets module ATS0=1 ? one ring before auto-answering ATS9240=921600 ? sets the baud rate ATS504=0 ? shows all debug ATS9084=0 ? UART latency ATS9080=10000 ? UART latency in microseconds ATS9011=1029 ? RFCOMM Frame size AT&W ? Writes the values to the module ATZ ? resets module AT+BTP ? enables connectable and discoverable mode for pairing
