Send packet continuously over nus

[Fiske]

Is it OK  to send multiple packet continuously over nus at below way without waiting for packet transmit complete?

      i=UserUart.RxBuf[1]+2;
           index = 0;
           while(i>0)
           {
             if(i>20)
             {
               err_code = ble_nus_string_send(&m_nus, UserUart.RxBuf+index, 20);
               if (err_code != NRF_ERROR_INVALID_STATE)
               {
                   APP_ERROR_CHECK(err_code);
               }
               i -= 20;
               index += 20;
             }
             else 
             {
               err_code = ble_nus_string_send(&m_nus, UserUart.RxBuf+index, i);
               if (err_code != NRF_ERROR_INVALID_STATE)
               {
                   APP_ERROR_CHECK(err_code);
               }
               i = 0;
               
             }
               
           }

Hi Fiske,

Yes you can. You will receive TX buffer full return code when the buffer is full (7 packets with high bw) and this way keeps the CPU running all the time.
