Hi everyone,

According to the previous question that I have to create two UART for PTM and Display.

Where can I learn about setting the UART interface for PTM and Display at the same time?

Best regards,

Hey Lulu,

I've assigned an expert to help you. Which SDK are you using? What project are you using as your base project?

Hi Ammar,
I am using simplelink_cc13x2_26x2_sdk_5_20_00_52_for_CC6252r and project is simple_peripheral_oad_offchip_CC26X2R1_LAUNCHXL_tirtos_ccs.

Thanks and regards,

Hi Lulu,

The more direct approach is to configure the NPI to use the second UART. To do so, using SysConfig, enable a second UART interface - I have called it CONFIG_NPI_UART. Note the pins used for Tx and Rx.

Then, in the file NPI/npi_tl_uart.c modify the code opening the UART to use the newly created UART:

    // Open / power on the UART.
    uartHandle = UART_open(CONFIG_NPI_UART, &params);

Build and test your code. Make sure to input the HCI commands on the proper pins.

I hope this will help,

Best regards,
