nRF51822 EV Board BLE400

[jimmy.kim]

I bought a EV board below to develop in the nRF51822 (www.wvshare.com/.../BLE400.htm)

I have installed all necessary tools like Keil MDK-ARM, J-Link, nRF51 SDK and nRFgo Studio. But I couldn't flash with Keil MDK-ARM due to error "No J-Link device found" and it can not connect to device with nRFgo.

Is there any guide to use BLE400 board and any information about supported tool chains(Keil, JLink, nRF51 SDK, nRFgo) version?

Do you have an external debugger connected to the board? There is no debugger on the BLE400 board, so you need an external one (something like this: www.segger.com/jlink-lite-cortexm.html).

If you scroll down to the bottom of the page, www.wvshare.com/.../NRF51822-Eval-Kit.htm, they have listed one they recommend.

On the bottom of this page, www.wvshare.com/.../BLE400.htm, you find the download for demo codes, datasheet, etc. Maybe you find a guide in there.

If you get yourself a J-Link, you can use the BLE400 board as an nRF51 DK, and use the nRF51 SDK with Keil, nRFgo studio etc.

Thanks a lot, So, I brought a J-Link ARM USB-JTAG Adapter. I will try to do again with this one. I will ask again if there is any other problem.

Thanks
