how to send all the array value in ble_nus_send

[ps_anu]

Hi, 

 i am using sdk 16 , nrf52832 .Merged with two sensors , i am storing it all in an array 

example 

uint16_t array[7];

array[0]=67; array[1]=90; array[2]={90}; .so on 

using Sprintf i have converted all the array into string, passing the string over ble_nus_data . 

i am not receiving any data in the phone 

ble_nus_data_send(&m_nus, str, sizeof(str),m_conn_handle); please suggest me , i want to send all the data into single packet

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 ?

what app are you using on the phone?

[ps_anu]

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]...

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 still haven't answered the question:

[ps_anu]

how to check that ? please 

[awneil]

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.

I am sending it directly not in uart_event_handle
