nRF51822: Unable to flash s110 softdevice using android app mcp over the air

[huyento]

Hi all,

I have failed when try to flash a new softdevice s110 to the target device is Wunderbar's sensor module which is using nRF51822 chip. Flashing application has no problem, however when flashing softdevice it was corrupted after the DFU has started to transfer data.

The application I used for flashing can be found here: play.google.com/.../details

Does anyone have any idea?

Thanks in advanced!

PS: please don't tell me better to ask in Wunderbar's forum. I would like to confirm if there is any possible issue with my Nordic environment as well.

Huyen.

Hi Hung,

Thanks a lot for your help! I have no clue to say about the original softdevice and the installed bootloader or the nRF51 SDK on that wunderbar. They don't share this information.

However, from their opened source code place, they state that users have to dowload the SDK version 8.0. So from what you say, it seems I have to update the bootloader too. Could you please share a link where I can get an appropriate bootloader for SDK 8.0 ? And should I use the nrf Toolbox DFU instead as Stefan stated here ?
