DFU over BLE using nRF52840-Dongle fails with error code 8

[Ivlampiy223]

Hello!

I'm trying to perform DFU over BLE using a nRF52840-Dongle (PCA10059) devkit. I'm getting the following error:

nrfutil dfu ble -ic NRF52 -pkg '/Users/user/Downloads/package.zip' -p /dev/tty.usbmodem -a 12:34:56:78:99:00

I've tried to add '-cd 5' and '-f' options, but error still happens. 

I've seen a similar question, but there is no solution.

Hello,

I see you are using nrfutil dfu ble, which is wrong, as you intend to update the dongle via USB, and not use it to obtain another device via BLE. Instead you should use nrfutil dfu usb-serial.

[Ivlampiy223]

I don't want to update my dongle. I want to update an external device using dongle. 

[Einar Thorsrud]

Ah, I see. I read your question too quickly. I would not have expected the "Failed to ble_gap_scan_stop. Error code: NRF_ERROR_INVALID_STATE" error in this case.

Which version of nrfutil do you use? And which connectivity firmware have you flashed on the dongle? Does it work if you first use the BLE app via nRF Connect with the dongle, and program the connectivity firmware from there (ensuring that the connectivity firmware version matches the pc-ble-driver)?

[Ivlampiy223]

Nrfutil 6.1.0, nRFconnect 3.5.0, bluetooth low energy 2.4.0.

It works correctly with nRF connect. 

I tried firmware that suggests bluetooth low energy app, I tried to add -f option to nrfutil dfu ble command, no changes.

One more detail: I have a custom application with pc-ble-driver 4.1.2. I'm using it to scan devices, select one and run nrfutil. Before running nrfutil I deinitialize dongle with the following commands:

sd_rpc_conn_reset(adapter, SOFT_RESET);
sd_rpc_close(adapter);

[Einar Thorsrud]

Hi,

I see. Your nrfutil command is correct and should work, and versions also seem good. Do you see this error if you power-cycle the dongle before you do this, so that it is in a known state (as you have used it before)?
