@idanronen , I am not an expert but did manage to accomplish what you are doing about a year ago. I can tell you that you are supposed to get two com ports from BMP. Also, where your screen shot says "SW-DP scan failed" means BMP cannot find any 'targets' on the nrf52. You should get back something that looks like this from the scan:
Available Targets:
No. Att Driver
1 ARM Cortex-M
2 Nordic nRF52 Access Port
I performed this operation on ~10 nrf52832 and only one failed the scan. I never found out how to solve it.
Also, your use of the attach command is incorrect. You appear to be trying to attach the com port 13. If the swdp_scan had worked corrrectly, you would then attach the target that shows up in the scan. In my example output, it would be "attach 2" - the nRF52 Access Port.
That adds what I know, hope it helps a bit.
Yes it is possible, using the SWDIO and SWDCLK pads.
I programmed one to operate with MySensors using a black magic probe, but the J-Link also supports SWD programming.
The tricky part is connecting to the pads. I just soldered on some wires -- not a very elegant solution, but it worked.
You can get a reasonably priced J-Link EDU from Adafruit:

@Yveaux Yes I had manually changed MyConfig.h to reflect the channel number I use. I thought I had read that was the way to do it. Okay thanks for putting me straight. Good to know it was just normal behaviour. I'll add it to each of my sketches in future.
Thanks.
