https://devzone.nordicsemi.com/f/nordic-q-a/19829/how-much-data-can-send-using-nrf51822Hi, I&#39;m working on nrf51822 with soft device s130. I&#39;m trying to send a data packets from the nRF51822 over BLE to an android device. I want to know how much data I can send through ble.? Is it possible to send around 20 MB of data..?en-USTelligent Community 13Mon, 27 Feb 2017 14:03:53 GMThttps://devzone.nordicsemi.com/thread/77121?ContentTypeID=1Mon, 27 Feb 2017 14:03:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1ec52015-dc53-4f81-abd6-8e032506fe7cSigurd<p>Hi Jason,</p> <p>You will need to split the 400 bytes in 20 bytes packets, and send them using notification. You will also need to configure your central to use a 7.5 ms connection interval to achieve maximum throughput. <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.sds/dita/softdevices/s130/ble_data_throughput/ble_data_throughput.html?cp=3_7_2_0_16">See this</a> S130 throughput infocenter-page for more information.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/77120?ContentTypeID=1Mon, 27 Feb 2017 07:59:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3cbcf368-1bd1-4352-bdf4-4fa33339450aJason<p>Hi,Sigurd</p> <pre><code> how the central device send a mount of datas (400Bytes) to the peer to achieve the maximum throughput supported by the S130?

The throughput will depend on what connection-interval and the number of packets per connection-interval the phone supports. The maximum throughput supported by the S130 SoftDevice is 149.2 kbps.</li> <li>Yes, but it will take some time to transfer that amount of data.</li> </ol><div style="clear:both;"></div>
