DFU example code as master

[roger.k]

Hi. I'm using nRF52832, SDK13.0.0. I'm developing not only peripheral side but also central side.

I already made peripheral side referring to DFU example code. But i don't know how can I make the code for mater. So I want to know how to DFU using nRF52832 as central.

Do you have any sample code for this? or any recommandation?

I need your help.

Hi Roger,

Unfortunately, we don't have an example for that. You might need to follow the documentation on the DFU protocol to perform a DFU update. You can refer to our DFU library on Android to get started.

We have an example for DFU host but it's for Legacy DFU and it's for SPI.

The only source of documentation we have for now is on info center. You can have a look here. It defines the opcode and the message sequence chart you can follow.

I would suggest you get hold of a sniffer trace when you use the DFU app on the phone or PC to perform a DFU update. You can use this sniffer trace as the reference to create your own DFU master.
