I have not seen any mention of a BlueZ based BLE DFU library other than here, which was a long time ago.
I will require this library for my current project so I'd like to see if there are any plans within Nordic to produce this,
If there is not, then I'd appreciate any suggestions of resources to base the library off of. In the Secure DFU docs
there is only mention of nrfutil the mobile apps, and nRF Connect Desktop as DFU controllers. Are there any other
resources that would assist in the development of a BlueZ based library for BLE Secure DFU?
I just found this recently as well web-bluetooth-dfu, which should be very helpful.
We do not have any other BLE DFU library implementations than those you have mentioned in your question. Any of them can be used as a reference implementation to use as a basis for developing your own library though. You may also find the DFU protocol documentation useful in that regard.
Thank you Einar for the response and info!
