Adding UART in ble_app_template

[Muqarrab]

Hi,

1-I have successfully developed an app ...\nRF5SDK17009d13099\nRF5_SDK_17.0.0_9d13099\examples\ble_peripheral\ble_app_template.

2-I have set a UART example to send data from Arduino and successfully send data from Arduino and receiving on nRF52840. I have used this example code:  ..\SDK\nRF5SDK17009d13099\nRF5_SDK_17.0.0_9d13099\examples\peripheral\libuarte 

3- Now I want to add the UART part in my ble_app_template. But getting the following error. kindly suggest a solution? or how should I add in ble_app_template?


Thanks!

Hi, 

Please refer to the compiler log to enable the Timer module and Timer instance in the sdk_config.h.

Hi Amanda Hsieh Thanks for reply.

Can you please mention which one I have not enabled? I have attached sdk_config.h.

4442.sdk_config.h

Hi, 

Enable TIMER_ENABLED and TIMER0_ENABLED in the sdk_config.h.

Please be aware that nRF5SDK17009d13099 is replaced by nRF5 SDK v17.0.2 for bug fixing. If you are using v17.0.0 for development, it is strongly recommended to switch to v17.0.2.

Hi, Amanda Hsieh,

I have placed this project in the new SDK and getting the following error.

Hi, 

Try this file ble_app_template_plus_libuart_278646.zip and put it under nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral. It should build without error, but you have to debug it by yourselfe.

Thanks, Amanda Hsieh

Now code is successfully run.
But When I add the following part in the main BLE stop adverting and am unable to receive data from UART.

    err_code = NRF_LOG_INIT(app_timer_cnt_get);
    APP_ERROR_CHECK(err_code);


    NRF_LOG_DEFAULT_BACKENDS_INIT();


    nrf_libuarte_async_config_t nrf_libuarte_async_config = {
            .tx_pin     = TX_PIN_NUMBER,
            .rx_pin     = RX_PIN_NUMBER,
            .baudrate   = NRF_UARTE_BAUDRATE_9600,
            .parity     = NRF_UARTE_PARITY_EXCLUDED,
            .hwfc       = NRF_UARTE_HWFC_DISABLED,
            .timeout_us = 100,
            .int_prio   = APP_IRQ_PRIORITY_LOW
    };

    err_code = nrf_libuarte_async_init(&libuarte, &nrf_libuarte_async_config, uart_event_handler, (void *)&libuarte);

    APP_ERROR_CHECK(err_code);

    nrf_libuarte_async_enable(&libuarte);

Here is my main file. Can you please mention where I am making mistakes while adding both projects as both are working fine separately?

Please create a new support case with debug log for the new issue.
