OTA programming for nRF52832

[dineshk]

Hi Nordic Tech support team,

I'm Hardware design engineer and working on wearable IoT design and would like to implement OTA programming for nRF52832 Bluetooth SoC.Kindly support me for below my queries...

1)Do we need any hardware design change for implementing OTA firmware programming in our end application?

2)Do we need to include Flash memory externally interfaced with Bluetooth SoC specially for OTA firmware upgrade or We can do the same using internal memory available in Bluetooth SoC?

Looking forward for your positive response!!

Thanks Dinesh Katkar

Hi,

You do not need any additional hardware to perform DFU over the air and the internal memory is sufficient. You can have a look at the setting up DFU on the nRF5 DK to get a better feel for DFU.

Best regards,
