Disabling flow control solved the issue

Changed APP_UART_FLOW_CONTROL_ENABLED to APP_UART_FLOW_CONTROL_DISABLED

Hi Reuven,

Thank you for ur response/suggestion.

Currently we are developing our project using nRF52 SDK, anyway we just started through the documentations/ courses for nRF connect SDk. But it may take time as we need to use multiple peripherals in single project like UART,SPI,I2C . We are also using SAADC and softdevices for the project. So planning a demo version using nRF sdk in the custom board for now.

Is there any example projects available with these peripherals ? If yes, that will be helpful. But as per current knowledge we have to add different peripherals one by one to the project

But if some configuration issue persists ,how can it work properly in nRF52832 DK as expected ?

Edit

After Debugging via RTT Failed receiving NUS message. Error 0x04 is found inside nus_data_handler(). And commenting the do while section resolves the BLE transfer issues. Here also UART transmission seems the issue

  for (uint32_t i = 0; i < p_evt->params.rx_data.length; i++)
        {
           BLEDataBuff[i]=(p_evt->params.rx_data.p_data[i]);
            do
            {
               BLEDataBuff[i]=(p_evt->params.rx_data.p_data[i]);
                err_code = app_uart_put(p_evt->params.rx_data.p_data[i]);
                if ((err_code != NRF_SUCCESS) && (err_code != NRF_ERROR_BUSY))
                {
                    NRF_LOG_ERROR("Failed receiving NUS message. Error 0x%x. ", err_code);
                    APP_ERROR_CHECK(err_code);
                }
            } while (err_code == NRF_ERROR_BUSY);
        }

thanks & regards

Hi,

It looks like a configuration issue, can you switch to newer SDKs using Zephyr , would be easier.

Thanks,
