different between nrf51DK, nrf52DK and Segger JLink

[philipyeung]

Hi, I am new on BLE development and a bit confuse on choosing development kit.
After search around, I learned the following, please tell me if any wrong:

1. Segger JLink can program / debug almost all the nrf51x / nrf52x series chips.
2. both nrf51DK and nrf52DK have a Segger JLink on it. So both DK can do whatever Segger JLink can do.
3. nrf51DK and nrf52DK contain plug and play pins for nRF chip and other board enhancement. So the DKs are more likely for PCB design for nRFs.

For my case, I am going to buy some nRF51822 and nRF52810 module, installing a button on GPIO, flashing the program and custom control the button, advertisement , Rx/Tx, etc.

Is it the Segger JLink enough for me to program and play around nRF51822 and nRF52810?

I want to know more about the CAN DO & CAN'T DO of nrf51/52DK  VS Segger JLink.
Thank you.

None of this has anything specifically to do with BLE

1. Segger J-Link can program any Cortex-M microcontroller - plus a range of others
2. The thing on the DKs is a cut-down J-Link with certain restrictions - but it should do all you need for nRF development
3. I don't understand your question here.

Do you mean I have wrong direction to choose nrf51DK, nrf52DK or Segger JLink on developing BLE? Then what tools will you work on BLE? please advice.

As (3), I just want to say, DKs are more for chip PCB design / development. And J-link is more for progarmming / debug. Is it right?

By the way, thanks for your info.

What I mean is that the functions and use of these tools is just the same as for any other microcontroller - with or without BLE.

Your answers suggest that you have no experience in developing for microcontrollers - is that right?

If so, you would probably want to spend some time getting familiar with the basics of microcontroller development before adding the complications of BLE!!

Do you have experience with programming in general?

And/or with basic electronics?

No, the DKs are not "more for chip PCB design" - the whole point of a SK is that it lets you get started without having to do any hardware design & manuifacture!

Yes, a J-Link is a programming and debugging tool.
