Use DFU to update AP over BLE(Single Bank)https://devzone.nordicsemi.com/f/nordic-q-a/1252/use-dfu-to-update-ap-over-ble-single-bankI use 51822 nrf6130 &quot;device_firmware_updates&quot; example to update AP. When I build &quot;dfu_dual_bank&quot;,the update will success. But when I use &quot;dfu_single_bank&quot;,the update will fail, my phone master control panel AP will show &quot;GATT error&quot;,please tell me howen-USTelligent Community 13Mon, 06 Jan 2014 14:02:26 GMTRE: Use DFU to update AP over BLE(Single Bank)https://devzone.nordicsemi.com/thread/5789?ContentTypeID=1Mon, 06 Jan 2014 14:02:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e94b072f-fdc2-4e62-a02c-6df08b86f354Hung Bui<p>Hi Elliot, Unfortunately, we haven&#39;t created single bank DFU for BLE. You may have to make one on your own. The single bank HCI is a good place to start from. If you have issue implementing, please let me know.</p><div style="clear:both;"></div>RE: Use DFU to update AP over BLE(Single Bank)https://devzone.nordicsemi.com/thread/5788?ContentTypeID=1Mon, 06 Jan 2014 03:21:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e137960-f497-4866-992f-2fc0fec1c7dcElliot.Chao<p>Yes, I want to use single bank to update firmware because code size issue. Can I modify dual bank source for single bank by myself? Or Nordic already have single bank over BLE example?</p> <p>Thank you.</p><div style="clear:both;"></div>RE: Use DFU to update AP over BLE(Single Bank)https://devzone.nordicsemi.com/thread/5787?ContentTypeID=1Fri, 03 Jan 2014 14:08:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1aef391f-e96e-46a3-aec8-ea1fa9e4f580Hung Bui<p>@Elliot: DFU over BLE with single bank is currently not supported by the bootloader example. The current dfu_single_bank is only for UART.</p> <p>Have you modified the firmware to create dfu single bank for BLE ?</p><div style="clear:both;"></div>
