That's a very old SDK - even for nRF51!

Note that nRF51 are not recommended for new BLE development:

Getting started is always easier if you start with current stuff!

Yes, the SoftDevice is delivered as a Hex file. You don't need to "open" the hex file - you just program it.

Instructions are in the SDK documentation:

infocenter.nordicsemi.com/.../getting_started_softdevice.html

The SoftDevice is the BLE protocol stack - so, without that, you cannot do any BLE stuff.

No, because the softdevice file was in hex format, I couldn't open it in keil. But when programming, I full erase the chip.

After programming, I don't see any response from the chip.

For new development I recommend to get an nRF52-DK, the nRF52-DK also support programming and debugging of external hardware (provided that VDD is approx 3V) using the on-board SEGGER J-Link debug out header.

Then following the User Guide of the nRF52-DK to set it up and get started with nRF5 SDK.

Did you program the SoftDevice?

"factory setting" is that the Flash is all erased - so simply do an erase-all.

Note that ST-Link, as the name suggests, is an ST product - nothing to do with Nordic. It is not designed, sold, or supported for use with non-ST microcontrollers.

You would make your life simpler using a supported programmer/debugger.

You would make your life simpler using a Nordic Dev Kit - at least until you are familiar with the product and the tools.

And that would give you a "free" J-Link!
