Setting up SDK in Keil and softdevice for nRF51 DK with nRF51822 device

[nvj]

I have just begin using nRF51 DK board which has chip with label PCA10028, V1.2.2, 2017.4. Seems to me the device is nRF51822

I also downloaded the nRF51 Development kit user guide.

I have just installed Keil. In the boards section of pack installer, I can locate nRF51 PCA10028 board but it shows only version v1.0.0. So I think I need to externally download latest compatible SDK and softdevice from NordicSmi website

I therefore want to know

• Which is the latest compatible version of nRF SDK I can install and how to install it in Keil to be able to develop software for this particular chip version and board
• In section 1.3 section of user guide, I see list of various Softdevices like S110, S120, S130, S210, S310. Want to know which softdevice is compatible with this board and how to flash it
• Any Nordic or Segger software tools that I should install to flash/debug

Thanks

If you're just starting, why not start up to date?

You know that nRF51 is not recommended for new BLE designs?

I understand your point that its not recommended for BLE development but not deprecated yet.

But I have just been handed over this board to work with by my supervisor. Maybe we will update to nRF52 in near future. But I have to work with this board for the moment. 

Also, as I read the silkscreen of the nRF SMD chip on the board, it seems its not nRF51822 but rather nRF51422
