BLE_NUS RX strcmp

[Sorrow91]

Hey all,

I'm trying to get the Nordic UART service with the nRF Toolbox App (Android). But always when I send "Hello" from the nRF Toolbox App, for example, I don't only get "Hello". In putty I can see something like "Hello," or "Hello▒" for example. So I can not use strcmp properly.

Here is how I receive the data:

static void nus_data_handler(ble_nus_evt_t * p_evt)
{
		if (p_evt->type == BLE_NUS_EVT_RX_DATA)
    {
			NRF_LOG_DEBUG("Received data from BLE NUS. Writing data on UART.");
			NRF_LOG_HEXDUMP_DEBUG(p_evt->params.rx_data.p_data, p_evt->params.rx_data.length);
										
			printf("\r\nReceived: %s\r\nSize: %d", (p_evt->params.rx_data.p_data), sizeof(p_evt->params.rx_data.length));    						
			}
		}
}

Can someone help me with my problem? What am I doing wrong?

Kind regards

Hi,

I'm not able to replicate this. Are you using the latest nRF-Toolbox version? Do you see the same behavior on other terminals also, such as Termite?

Hey Sigurd, thanks for your answere, I have done it now with the memcpy function. For example:

char nus_data[20];
memset(nus_data, 0, sizeof(nus_data));			
memcpy(nus_data, p_evt->params.rx_data.p_data, p_evt->params.rx_data.length);

I will close the question. But thanks for you effort!

Good to hear that you solved the problem with using memcpy instead ! :)
