nrf51822 yunjia board

[normanfust]

Hello everyone, After days of struggle with the yunjia board it seems that I cannot download any program to it. I tried falsely to download program for the PCA 10028 but it seems that it's a quite different board. My question is what nrfSDK and what soft device to use to make it work? SDK of 8 and s110 is a good choice or are there any incompatibilities?

We don't know what chip you got on the board. First, identify the chip revision basing on this table, and then use SDK and SD like it is described here.

Thank for the reply, I' ve read the symbols on the chip and found out it is a rev 3. So according to the table it means thaat I can use the SDK 12.x.0 along with SD 130. But when I go to directory nRF5_SDK_12.2.0_f012efa\examples\peripheral\blinky I got only versions for the nrf51422 and nrf52840 boards. Should I change the CFLAGS in makefile to match nrf51822 to make it work?

nrf51422 will work ok, you can use it.
