I would like to use Zephyr with my Frdm K64f to program an HC-05 Bluetooth module using AT commands. Could you help explaining were I need to start?
For now my board are running cdc_acm composite example and it works fine, with two serial comm terminals it's send data each one. I'd like to change this example to use one cdc_acm and UART_3. cdc_acm <---> UART_3.
