We are working with a custom hardware, so I can't help you there. But if you're committed to the project it shouldn't be hard to figure out what you need to change. Note that there is a new SDK from Nordic that has a fully working sample of a bootloader. Jimmie

Hi Jimmie

I have nRF51822 PCA1001 evaluation kit

As you have said that there is an example named nrf6310_experimental in the folder 6310 of nrf51822 SDK , and this example must be for 6310 board

So my question is ..

What modifications does I have to make in the program in-order to use the example for PC10001 board.

There is a folder caller nrf6310_experimental that gets installed with the SDK. It contains sample code for a bootloader.

Hi Jimmie,

Thanks for sharing this with me, are you referring to the ble_app_hrs project for the bootloader example? Could you tell me which file I should look at for the bootloader source code?

Thank you! Joseph

Nordic has an example of a bootloader that can be used to upgrade the firmware but it is not doing it over the air. We have implemented a bootloader that initializes the SoftDevice stack and provides a firmware upgrade service.

I our case we have an external spi flash where we buffer the firmware image before we write it to internal flash, but as long as you're careful not to write to flash while the radio is active it should be possible to do without an external buffer. Radio notification can be used to see when the radio is active.

Good luck.
