Device Firmware Update over NFC

[David Caroppo]

Hello,

I would like to implement Device Firmware Update (DFU) over NFC.

Is this supported, and is there any recommended way to implement it?
Are there any examples, reference projects, or guidelines for transferring a firmware image via NFC?

My goal is simply to understand whether DFU over NFC is feasible and how it can be set up.

Thank you.
David

Hi David,

There is no support for DFU over NFC at all. It should be technically possible, but it would be up to you to implement it, including supporting NFC transport for DFU on the nRF side and tools on the other end, etc. You could probably use TNEP or writable NDEF, where TNEP is perhaps more suited but this currently has limited support on for instance mobile phones.

I do not recall ever seeing a request for DFU over NFC. Is it a requierment for you? If not, perhaps other transports could be considered (could it be possible to initiate DFU over NFC in an application specific way, and then continue over for instance BLE?)

Br,

Einar
