nRF Toolbox DFU error code DFU DEVICE DISCONNECTED (0)

[mike]

Can anyone explain what that error code is meant to mean?

With the example sdk7.1 dfu bootloader, hrs_with_dfu app built unmodified and sd110 7.1, I get this error on attempting to load to an nRF51822 rev2. I get this with sdk8.1 and sd8.1 too.

code built with uV4

Problem sorted. Don't run the DFU application in the toolbox (Duh)

Do this:

Select the device in Master Control Panel. The device is advertising as "DfuTarg". Connect to the device and perform service discovery. Observe that the connected LED is lit and the advertising LED is off. Master Control Panel will recognize that the device supports Device Firmware Update, and the "DFU" button in the user interface will become available.

Click "DFU" and select the zip file that contains the firmware image.
Click "Program". Observe that the update procedure starts. When the progress bar reaches 100%, the update is complete.

@mike: I was testing here with nRFToolbox app, and I don't think I got any issue with that. Could you take a screenshot or a log file (with nRFLogger) when you do DFU with nRFToolbox ? Did you have the issue every time you tried or just occasionally ?

Hi Hung,

I glad you ask, as my problem wasn't solved - that was a one-off success, not to be repeated.

Below is the logger trace I see. If a wireshark trace would be more useful, I will create one and attach it. I am using Android 4.3.1, Cyanogenmod 10.2, on an HTC One-x.

I see a similar failure to download issue on IOS with the latest nrf toolbox.

Regards,

Mike.

@mike: Could you send me the .hex file and .dat file you used ? Have you tried the examples hex file and dat file in your phone located at Nordic Semiconductor/Board/PCA10028 ?

A sniffer trace would also tell more on what went wrong.
