How do I use UARTE 1 with ble_app_uart?

[katokatsu6412]

Hello.
I move ble_app_uart with a combination of nRF 52840-DK and SDK v 15.2.0.
Using UART 0 or UARTE 0 confirms that it can communicate with nRF 52832 on the Central side, but communication using UARTE 1 fails.
What is the reason why data can not be sent or received?

We set 1 to APP_UART_DRIVER_INSTANCE in sdk_config.h and set it to NRFX_UARTE_ENABLED and NRFX_UARTE 1 _ ENABLED.

Hi,

How is it failing? Did you set UART_ENABLED, UART1_ENABLED, and UART_EASY_DMA_SUPPORT as well?

I would recommend using the Serial port library when using both UARTs on nRF52840.

Best regards,
Jørgen

Yes, UART_ENABLED, UART1_ENABLED, UART_EASY_DMA_SUPPORT is also set to 1. However, data is not transmitted from Tx of UARTE 1 even if data is transmitted.
How can I use the nus service with the serial port library? In the examples of SDK V15.2.0, an example of BLE communication using the serial port library could not be found.

Hi.

The peripheral\serial_uartes example have an implementation of the serial port library which Jørgen proposed, I suggest you take a look at that.

Here is the link to the serial port API also. You simply need to use the serial port API instead of the UART module API.
