DFU over usb serial on Android device

[mw1]

Hello,

We would like to perform a DFU over serial cdc connection on Android. We currently perform DFU via BLE using the Android DFU library and were wondering if a similar method exists for serial CDC connections.

Thanks!

Thank you for the quick response! We are simply evaluating our options. The BLE implementation was very easy thanks to the Android DFU library, and we were simply wondering if there was a similar option for serial. We will look into implementing ourselves. Do you have a good starting point you could point us to?

Hi,

The DFU protocol itself is the same regardless of transport, so you can refer to the Android-DFU-Library (which you have already been using) for that. For serial transport specifics you can refer to for instance the nrfutil implementation (which is in python but can perhaps still be used to get an overview) and also the documentation.
