I have a WiFi Module with Bluetooth, how do I enable RTS/CTS (Hardware Flow Control) on the Bluetooth /dev/tty* UART port in Linux?
Configure the UART parameters using
stty before running
btattach. Use the "crtscts" option to enable RTS/CTS.
crtscts is the option to enable RTS/CTS hardware flow control on the serial port, and -crtscts is the option to disable RTS/CTS hardware flow control. Note the hyphen (Enable =
crtscts, Disable =
stty -F /dev/ttymxc0 crtscts
(Make sure to change the "
/dev/ttymxc0" to your actual device.)
After you have set RTS/CTS flow control, you can check the current settings of your UART device with the
stty command to ensure that it is correctly configured:
stty -F /dev/ttymxc0 -a
This command will display all the settings for the specified UART device. Look for
crtscts in the output, which indicates that RTS/CTS flow control is enabled.
To disable RTS/CTS hardware flow control on a serial port using the
stty command, you can use the
-crtscts option (including the hyphen).
stty -F /dev/ttymxc0 -crtscts
