https://devzone.nordicsemi.com/f/nordic-q-a/42720/large-data-transfer-over-bleHello, I want to transfer a large file (approx. 1.5MB) over BLE using nRF52 Module in a way where BLE Host and BLE Controller will be on the nRF52 SoC and the application will be running on an External MCU. Both the controllers will be connected throughen-USTelligent Community 13Tue, 19 Mar 2019 15:20:02 GMThttps://devzone.nordicsemi.com/thread/177123?ContentTypeID=1Tue, 19 Mar 2019 15:20:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:196c531f-2e07-4ef3-bc53-0c8733c1a686Jimmy Wong<p>HI,<br /><br />You can base on my example <a href="https://github.com/jimmywong2003/nrf52_ble_transfer_jpg">github.com/.../nrf52_ble_transfer_jpg</a> approach as reference.&nbsp; request to get data with software flow control.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/168426?ContentTypeID=1Tue, 29 Jan 2019 11:25:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f47c11c-5acc-48ec-a08f-ab91b6e5c0f0Keval Soni<p>Yes, thank you for your response.</p> <p>I have studied serialization and found out that I can dump a pre-compiled code in the nRF52 chip and I can send BLE operation commands to nRF52 using an external MCU over UART without touching the code in nRF52.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/166887?ContentTypeID=1Mon, 21 Jan 2019 14:44:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6712fb3e-b918-41ad-ad4d-9b706fd06b10haakonsh<p>I believe you&#39;re looking for the&nbsp;<a href="https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/lib_serialization">Serialization</a>&nbsp;library.</p><div style="clear:both;"></div>
