I am running 5.2 sdk's UART under experimenta\ble_app_uart, I assume it works with www.nordicsemi.com/.../nRF-UART-2.0-for-Android-4.3
when Android app sends data to device, it is able to received in void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length) { for (int i = 0; i < length; i++) { simple_uart_put(p_data[i]); } simple_uart_put('\n'); }
however, nothing was sent to APP side, no notification sent to app side too.
also void UART0_IRQHandler(void) did not get called
what did I do wrong? wrong device example code used?
UART0_IRQHandler seems very strange, data_array[index] = simple_uart_get(); it return some pointer to data_array[index]; how ever, later it use index+1 as the length, and use the wrong way:(index >= (BLE_NUS_MAX_DATA_LEN - 1)
seems this is an example that all went wrong?
void UART0_IRQHandler(void) { static uint8_t data_array[BLE_NUS_MAX_DATA_LEN]; static uint8_t index = 0; uint32_t err_code;
/**@snippet [Handling the data received over UART] */
data_array[index] = simple_uart_get();
index++;
if ((data_array[index - 1] == '\n') || (index >= (BLE_NUS_MAX_DATA_LEN - 1)))
{
err_code = ble_nus_send_string(&m_nus, data_array, index + 1);
if (err_code != NRF_ERROR_INVALID_STATE)
{
APP_ERROR_CHECK(err_code);
}
index = 0;
}
/**@snippet [Handling the data received over UART] */
}
