Over the BLE bootloader

[ligang]

I want to refresh the program by bluetooth. Can Nordic provide some case? or Nordic don't provide this function?

[Roger Clark]

Yes.

See the various examples in the SDK.

Look for "DFU" in the SDK / API and the example names.

Yes, we provide a bootloader example that allows you to perform Over-the-Air(OTA) Device Firmware Update(DFU) using Bluetooth Low Energy.

You can find the documentation of our bootloader on this Infocenter page. (Note: This is for SDK v11.0.0 which uses the legacy bootloader, if you need signed firmware images you have to use the bootloader in SDK v12.0, here is the link to the documentation and here is the link to the step-by-step example guide.)

You can find a step-by-step guide on how to use the example bootloader on this Infocenter page.

Best regards
