Hello Eric,

1. Is it  that the mean of DFU equels "OTA DFU" referred in the "nRF52832_PB_v1.4"?

OTA DFU = DFU in our SDK. Have a look at the Bootloader and DFU documentation and our DFU examples.

2. I have SDK ver 15.3. Can that be compatible another versions?

 Can you please elaborate on what you mean? Have a look at our compatibility matrix. This shows the compatibility between the nRF52832 IC revisions, the relevant SoftDevices (SD) and their corresponding SoftDevice Specifications (SDS), and Software Development Kits (SDK).

Kind regards,
Øyvind

Hi Øyvind,

OK, I have understood DFU call "OTA DFU" when nRF52832 firmware uploaded from an smartphone aplication. Right?

Sorry for little of information.I m not good at English.

I wonder that SDK ver 15.3 DFU function is compatible under the SDK 15.3 ver or over.

Thank to give me information.

Eric.

Yes, you can update the FW using your smartphone application. We also have a getting started tutorial on DFU here.

 Our SDK is compatible within a major version i.e. SDK 15.3 is compatible down to SDK v15.0, but may not be compatible with e.g. v14.2. Always read the release notes.
