SDK12 ble_app_buttonless_dfu

[Sergy]

Hi,

Im tryin to use the ble_dfu service example from SDK12, I get DFU SERVICE NOT FOUND when trying to update from Android. Any suggestions what to look for?

I use S132v3, bootloader is flashed and I performed successful upload of the application via BLE when there was no app loaded.

I added the "char_md.char_props.write = 1;" change. I still receive the following error from nrfutil:

I made the following change to ble_dfu.h:

-#define BLE_DFU_BASE_UUID   {{0x50, 0xEA, 0xDA, 0x30, 0x88, 0x83, 0xB8, 0x9F, 0x60, 0x4F, 0x15, 0xF3, 0x00, 0x00, 0x40, 0x8E}} /**< Used vendor specific UUID. */
+#define BLE_DFU_BASE_UUID   {{0x50, 0xEA, 0xDA, 0x30, 0x88, 0x83, 0xB8, 0x9F, 0x60, 0x4F, 0x15, 0xF3, 0x00, 0x00, 0xC9, 0x8E}} /**< Used vendor specific UUID. */

nrfutil now gives a different error:
