I got this error when programming the Development Dongle. The dongle is recognized in the
Master Control Panel as a COM4 - xxxx, and when is connected a green led and blue led are ON

Firmware: MEFW nRF51822 0.10.0 UART baud rate: 1000000 bps

Master Control Panel 3.7.0.8517

Looking at the screenshot it is clear that the master control panel cannot see the board with the correct firmware. Is the board really located at COM5 in the virtualbox ? Has it been flashed with the correct hex file ?

Ensure that you have made the USB port available to virtual box so that windows can see the USB port. Ensure that the device manager on windows recognizes the board and loads a COM port driver (CDC) for it and a jlink driver for it. Flash the firmware for master control panel to the board File -> Flash programming. Point the master control panel at the right COM port.

Let me know how it does.

Ok, you seem to have the drivers. Additionally install the nRF51 tools if you have not done so from the download page. ( www.nordicsemi.com/.../nRF51822 )

Now verify that you have flashed the mefw to the USB dongle.

• Ensure that only a single Segger Jlink is connected at the point of flashing.
• Use Master Control panel to flash the MEFW firmware to the USB dongle Select the correct COM port, you need to select a COM port that looks like "COMxx - yyyyyy"

If you have successfully the flashed the MEFW, then the next step is to verify that your board does not need any modifications. See Master Control panel -> Help -> Open Help -> Supported Hardware

If you are still having trouble, get the log file from Master Control Panel -> File -> Log File and post it here
