My suggestion is to open Control Panel in Windows, and go to Add or remove programs. Then remove software from SEGGER and Nordic, restart and re-install MCP.

I followed your instructions but it was not successful. After programming the firmware there is just the green led on and it shows the same messages again.

I tried your instructions at another laptop and it works. After programming green led is on and also the second led lights white. The Log show also the device address, firmware version, ready, server has started, device discovery started.

I don't know why it works on one laptop and not on the other. On the laptop on which it works, there was never any Nordic software installed before (nRF Connect or nRFgo Studio).

Thank you for your help!

I installed a fresh copy of MCP from: http://www.nordicsemi.com/eng/nordic/Products/nRF51822/nRF-MCP-x64/46143

Plugged in PCA10000 to a USB port. Opened MCP and File->Flash programming, programmed either of the MWFW 0.9 or 0.11. Then I plugged out and in the PCA10000. Waited a few seconds before clicked on the Reset button in MCP, then I could successfully Start Discovery. Maybe you can try the same procedure?

Both nRF Connect and nRFgo Studio were closed the whole time.

Hello Kenneth.

I reinstalled MCP and nRF Connect. With MCP I am able to program the firmware (File-Flash programming). The firmware is MEF nRF51822 0.11.0. After programming I have the choice to unsecure the device. The Log of the MCP shows following:

Programming started.

Programming complete.

No response from master emulator.

If I try to scan for devices and press the "Start discovery" button and get following message: "No command complete event received" and the Log shows "Device discovery failed to start".

If I try it with Bluetooth Low Energy App in nRF Connect the program asks if I want to program the latest connectivity firmware. After accepting it says "Not able to find COM#".

I closed MCP when I tried with nRF Connect and closed nRF Connect when trying with MCP.

I just plugged in the usb dongle. Is there something I have to do before using the PCA10000?

Thank you for your help!

Using Master Control Panel (MCP) or nRF Connect for desktop is useful during development, and may in some cases give better control than using a mobile phone. I am not entirely sure what is the problem here, you should be able to program the required firmware for instance from File->Flash programming in MCP. Though you should make sure to close for instance nRFgo Studio, since nRFgo Studio may claim the COM port.

Best regards,
