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)?

[Einar Thorsrud]

Hi,

We just saw another issue where there seems to be problems combining pc-ble-driver 4.1.2 and 4.1.1. Can you try the attached nrfutil executable (8688.nrfutil_test.zip), which is includes pc-ble-driver 4.1.2?

nrfutil_test.exe dfu ble -ic NRF52 -pkg dfu-application-package.zip -p COM4 -a FF:AA:EE:99:66:AA

Hi,

I see from the log that using the test version of nrfutil (using pc-ble-driver 4.1.2) has no effect, so we can probably ignore that suggestion from now on. Going back a bit... Do you still get this problem if you power-cycle the dongle before you use nrfutil to do DFU?

[Ivlampiy223]

No, I don't

[Einar Thorsrud]

I see. Then this must be related to the current state of the pc-ble-driver firmware in the dongle, so it has to be cleaned up somehow. The easiest is probably to call sd_rpc_conn_reset() from application (which uses pc-ble-driver) before using nrfutil.

[Ivlampiy223]

I already mentioned that I finish connection with 

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

I will try SYS_RESET option

[Einar Thorsrud]

Hi,

Yes, you exposed my goldfish memory SYS_RESET is what we want here. That should be more or less equivalent with a power-cycle.
