UPDATE:02/28/2017

I MAKE A BOARD ,WANT TO KNOW DOES THIS PIC MAKE SENSE?

I WANT USE STM32F072B REPLACE JLINK OB.

STM32 HAS USB I WILL WRITE CODE MAKE A virtual serial port(USB-CDC).

Any Suggestions?

UPDATE:02/27/2017##

Now use new jlink nRF Connect can select port "jlink CDC UART Port(COM18)" on my PC.

and then got error (NRF_ERROR_TIMEOUT).

I have confused:

1. nRF Connect --> usb-->jlink--> swd--> chip
2. nRF Connect --> usb-->serial-->chip

which model is correct? or both of them are correct? Even the example on "nRF51_ble_broadcast_mesh_0.8.7" not run correct on the board. Eager to get your help!

EARLIER QUESTION

I 'm doing a ble mesh-DFU project,download nrf-connect-win32-ia32.zip

Demo board flash nrf-connect-mesh-official-serial-gateway-fw.hex

J-Link Software absolutely installed.

But when I open nrf-connect-mesh.exe its serial port could not selected.

PC device manager can see the port.

The nRF connect mesh show as blow:

What's wrong here?

PS: I also download nrf-connect-win32-ia32-25-Nov-2016.zip

It show blank like this:

This kind of problem is usually difficult to analyze, my computer is missing some files? Need your help!

Which board are you trying to run this on? USB-SERIAL CH340 is not what I would expect from any of the Nordic DK's. From this blog post, one of the requirements are: J-Link debugger (on-board nRF5 Development Kits and dongles). The COM ports from nRF5x DK and dongles should be something like: JLink CDC UART Port

I made the board myself.CH340 chip is a USB-SERIAL bridge. And I want to know if nrf-connect only recognize "Jlink CDC UART Port" When my jlink insert on the PC, show as "JLink CDC UART Port(COMM18)",nRF Connect can select this port but it will get timeout error(NRF_ERROR_TIMEOUT). I search question zone find this kind question need to be answered.
