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

................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.
blank screen on serial ....?

Hi,
What happens when you run the application? Does it assert somewhere? Try to use the debugger and see if the application stops somewhere.
where do you want to put the breakpoint ? what do you want to see ? thanks
Hi,
Could you put a breakpoint in the UARTE event handler and check that the correct event is generated when you send/receive data and check after the initialize routine that both functions are initialized correctly without any errors. The init functions should return 0 if they are initialized correctly.
Thank you!
regards
Jared

Hi Jared, thanks for the reply
case NRF_LIBUARTE_ASYNC_EVT_RX_DATA:
//nrf_libuarte_async_tx(&libuarte, text2, text_size2);
nrf_libuarte_async_tx(&libuarte, p_evt->data.rxtx.p_data, p_evt->data.rxtx.length);
I commented out the second line, now it's working,
Thanks
