Hey Wayne: We dont “officially” support the boards you mention as they are not in the supported BSPs. If you have an “official" nrf51dk that would be the best to get started on as we do support that currently.
Unfortunately, bletiny is a bit of a misnomer; it is not so tiny, and depending on which version you are trying to build it may be too large to fit in our current image slot; bleprph should work though. We may have a work-around for nrf51 bletiny soon but for now I would use bleprph. BTW, are you sure you have erased the devices you are trying to load the code on? There are protection mechanisms that you must disable in order for our newt tool to be able to erase/program flash. > On Jun 2, 2016, at 2:04 PM, Wayne Keenan <[email protected]> wrote: > > Hi, > > I've been trying to get the bletiny and bleprph apps running on a few types > of nrf51 boards but not having much luck. > > The 3 types are: > > 1.
