I have tried testing with different baudrates, 9600, 115200, 38400, etc. I observed that the time nRF51 DK takes to send 1Kbyte data is 24 secondsen-USTelligent Community 13Thu, 05 Nov 2015 07:44:39 GMThttps://devzone.nordicsemi.com/thread/37440?ContentTypeID=1Thu, 05 Nov 2015 07:44:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8ba20d8-00a8-459d-b22b-dfe61902b22frun_ar<p>The time it takes to send data from over BLE depends on the connection interval and the number of packets sent per connection event.
