I haven’t experimented with the NOW protocol yet.

Were you successful with the tips from DK?

Hi .. with NOW I need to know how once it makes a connection to keep sending data without having to disconnect each time. The example shows it sending 1,2,3… but it makes a connection each time.

Hi, These are the projects, that I am using … work fine for me ..

Try a version of this…

while(1) // stay on
 {
  getdata(data to be sent);
       if(data to be sent != NULL)
         {
          esp_now_send( date to be sent);
         data to be sent = NULL or "";
          }
 }

Here is the Protocol:
