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?

    I bought one of these boards too, and I thought it included a "debugger" to be used to flash the module. However, once I asked them, then they said I needed to get their debugger. So, I ordered that. The latter is also a knock-off of JLink(?)
    I was finally able to download the softdevice+application to the module, but took me sometime to get there, even though, I still have not figured out what they mean by "LEDs and user keys, compatible with other official boards, easy to use." I still don't know to which board theirs maps to, so that I will use the correct branch of the examples code to get the LEDs and keys right! Their prices are good, but I guess you get what you pay for! Moreover, their modules are not FCC or CE certified, if you need the certification look elsewhere. I don't have the official development kit, but looking back, I should have obtained that in the first place.
