Hey, 

I have some Thingy52 here and I would like to use them for a reasonable
application. I connected the J-Link to the Thingy52 and I am able to
flash it. My problem is just: How to connect it to the serial console
over the J-Link? I am not familiar with it. I just get the following
response: 

 J-Link connection not established yet but required for command.
Connecting to J-Link via USB...No handlers could be found for logger
"root" 2019-04-06 21:52:44,120 - WARNING # Host name for TCP connection
is missing, defaulting to "localhost" 2019-04-06 21:52:44,120 - INFO #
Connect to localhost:19021 2019-04-06 21:52:44,120 - ERROR # Something
went wrong connecting to localhost:19021 

 I soldered the pin header, connected a UART-to-USB adapter to it and
used the nrf52dk board to flash it. That works fine. But it probably is
better to just use the J-Link. So, I would like to know how to do this.
