To complete the question: if (once) the Thingy is provided with some custom bootloader which can work with UART or similar transport protocol then you might get rid of this but then still nRFgo probably won't be your friend and some custom application will be needed...

correct - there's no segger onboard as there is on the devkits so you need an external one. I like the JLink EDU myself as (as long as you're not commerical) it's cheap and works very well

endnode,

It sounds like it is not possible (functional) to connect the PC directly to the Thingy:52 without external hardware (nRF5x DK, Segger J-Link, etc.). In all cases, I will check the forum questions and infocenter for more detail.

Thanks for your help.

RK,

Step two in the thingy_sdk_v1.1.0/documentation/dfu_cable.html file from the Thingy:52 SDK.

As RK said Thingy has SWD PINs exposed so use any JTAG/SWD programmer and SW to erase nRF52 chip and flash new binaries. There are sections about this on Infocenter (using any nRF5x DK board with SEGGER J-Link OB is the easiest solution usually, there are many Q&S on this forum how to wire it to P19 or P20 of nRF5x DK board...)

in which document does it say that - I can't find it. I assume they are talking about a jlink cable but without finding the comment I'm not sure.
