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?

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]...

Did you successfully manage to transfer data using the unmodified SDK example ?

Again:

• For the length of a string you need to use strlen()
• What return value are you getting from the call to ble_nus_data_send() ?

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

i am getting the 23, 24  keep on changing

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