DFU - gatt connection error(0x81, 0x85)

[kibo]

Hi, I am adding DFU service to my app.

When I try DFU, 2 GATT errors have occurred.

I am using nrf52, sdk11.0

Thanks.

Hi Kibo, have you added DFU support as described in this guide?

[kibo]

Yes, I added 3 files(dfu_app_handler, ble_dfu, bootloader_util), 3 functions(advertising_stop, app_context_load, reset_prepare) and variables. I want to know when 0x81, 0x85 GATT errors occurred.

Could you attach your application main file to the question? Could you also upload the firmware image that you used for the update and the command that you used to generate it?
