We use the SDK with F4 and cc2564 to debug sppdemo. You need to input server and open 1 into the serial port in order to search for Bluetooth. Now develop the program, let cc2564 directly enter the address search part. You can directly enter the server mode by using the command CommandLineInterpreter("SERVER\r\n"), but the command CommandLineInterpreter("OPEN 1\r\n") is not executed successfully. Which function should we use to issue the command?Or how to set it to enter the pairing process directly?
