Hello Bjorn, I've been trying to program the fanstel BT840F evaluation board using my nRF52832 DK but I'm having problems. I've followed the documentation from fanstel which you've given above. I am unable to upload the softdevice to the BT840F board using my nRF52832's jlink. I am trying to do something along the lines of this.

Can you please tell me how to proceed further?

Thank you.

I had problem with Segger j link. I have output voltage only on Vdd=5V, and other output voltage is 0V, do you know what may be problem?

Yes, I would recommend buying a 52832 or 52840 dev kit to program the fanstel bt840 module. The dev kits have a segger j-link, which you require to program the module. This datasheet should be helpful too. In addition, I recommend taking a look at these two links: link 1, link 2.

Thank you, I will look all of them. One more doubt: do I need some development board or BT840 can work on its own?

I would start by taking a look at some of the documentation provided here. I would also recommend taking a look at our Nordic DevZone past answers, as well as our Infocenter documentation (link 1, link2, link3). Unless you have a Keil license, you may want to take a look at Segger Embedded Studios, as it is free for Nordic SDK users (see this link too). This link may also be helpful.
