Firmware update of Smart Remote 3
You can update firmware using nRFgo Studio. This guidance covers some basic steps. More details about the
firmware update procedure can be found in the firmware documentation.
If you are programming the DK add-on, the nRF52 DK has the SEGGER J-Link built in and can be used through
the USB cable. If you are programming the product example, the nRF52 DK can be used as the debugger.
For links to the tools, see Nordic tools and downloads.
7.1 Connect product example to nRF52 DK
The programming and debugging interface of the nRF52832 is accessed through a 10 pin connector (P1) on
the product example.
To be able to program and debug, the product example needs to be connected to a SEGGER J-Link device. In
this user guide we will use the nRF52 DK as reference, but the nRF51 DK can also be used. Make sure that pin
1 on the Debug Out connector on the nRF52 DK is connected to pin 1 on the P1 connector on the PCA20023
board. Figure 45: Pin 1 position on page 56 shows the position of pin 1 on the Debug out connector.

To connect the product example to the nRF52 DK, use a 10-pin flat cable. Connect the cable to the product
example so there will be a 1-1 mapping of the pins. Figure 46: nRF52 DK connected to the product example on
page 56 shows what the connection should look like.
