can we send the combined data in ble_nus_send

[ps_anu]

hi ,,, i am getting the four data from various sensors, then i want to combine all the four data and send in ble_app in variable , example x=10;y=30;z=34 using sprintf i am converting into the string . now using  data= strcat(x,y) , combining the data . is it possible to send the all data in single ble_nus_send. ble_nus_send(&m_nus,data,sizeof(data),m_conn_handle);

Hi,

If you format your data as a string, you should be able to send that data using ble_nus_data_send(), yes. Please note that if the string is too long not all of it will be sent. Therefore you need to check the value pointed to by p_length after the call, to see how much was actually sent, and then do a new call for sending the rest of the data. I recommend having a look at the UART/Serial Port Emulation over BLE examples for a reference how to use the NUS library.
