Unable to flash my P-NUCLEO-WB55 dongle

[ODEBO.1]

Using DFU. I repeatdly try to flash the dongle, it almost always fails and when it seems to start erasing prior to writing it ends up with :

$ ./STM32_Programmer_CLI -c port=usb1 -d /tmp/BLE_p2pServer_reference.hex

Previous attempts fails with "unsupported" command for this device, or asking for -rdu.

When -rdu is invoked it randomly telling me that RDP is 0xBB where it reads out 0xAA (no protection).

Have you tried to use the GUI Version 2.4.0? A far as i am concerned, it works more reliable than the cli version.

[ODEBO.1]

Thank you for your reply. I actually switched to CLI because the UI tool was behaving inconsistently. I had no issues with the Nucleo board so I concluded that the DFU part of the tool is just crappy. It works better (though not reliably) on Windows (7 here), and I could get the FUS, Stack and application downloaded properly to the dongle. This is surprising since it's a Java tool. Well I guess the serial port part is obviously not common to both platforms (Java has no good solution for this).

Since Windows is a no go for me, I think I'll use standard dfu tools on Linux or stick with the Nucleo dev board instead of the dongle.
