Go on - that's a basic 'C' programming question: exactly the same way that you'd get the return value from any function call.

Again, the SDK examples all illustrate this.

okay if i give 24 i am not getting the data , if give the length as 9 i am getting data in the app "245,567" only the two set array data .i dont know how does it is working

uint8_t array[8];
char str[8];
array[0]= 245;
array[1]=567;
array[2]=908;
array[3]=345;
array[4]=90;


 ble_nus_data_send(&m_nus, str, 9 ,m_conn_handle);

You're putting different data into the string - so it will have different lengths!

yes i can able to transfer the data

printf("%d", (int)strlen(str));

What return value are you getting from the call to ble_nus_data_send() ?

yes thank you for your response

i am not getting the data , i am using latest version ble5.0 phone and nrf toolbox

sprintf( data,"%d,%d,%d",array[0],array[1],array[2]);
 ble_nus_data_send(&m_nus, data, sizeof(data),m_conn_handle); // even i tried sizeof(array[0],array[1]...

If it's a string, you should be using strlen() to find its length.

What return value are you getting from the call to ble_nus_data_send() ?

Have you looked at the SDK examples which illustrate the use of the NUS ?
