Dear Members,
I saw this example,
I can not find this example on SDK 17,
How can I use UARTE0 and UARTE1 on separate port ? one is for debugging via USB and the other one for communicating with GPS UART ?
Any suggestions ?
Thanks

How can I implement this app with libuarte ?
\nRF5_SDK_15.2.0_9412b96\examples\peripheral\serial_uartes
thanks
................If you want to use two UARTE instances then you have to enable both instances in the config file and resources that the module is dependent on ( Timer and PPI) . Next you have to define an instance of the module and initialize it in the project. Again, the libUARTE example should be a good reference, it's pretty straightforward.

How ? What's PPI ? thanks
Hi,
Could you add an APP_ERROR_CHECK(err_code) after each call to nrf_libuarte_async_init() and see if the application asserts during run time.
err_code=nrf_libuarte_async_init(&libuarte, &nrf_libuarte_async_config, uart_event_handler, (void *)&libuarte); APP_ERROR_CHECK(err_code); err_code=nrf_libuarte_async_init(&libuarte1, &nrf_libuarte_async_config1, uart_event_handler1, (void *)&libuarte1); APP_ERROR_CHECK(err_code);
blank screen on serial ....?
