I'm not seeing any bluetooth error, are you? rfkill unblock all

armbianmonitor -u in the link it shows : https://paste.armbian.com/uzudezufit Linux version 6.12.74-current-sunxi64 (build@armbian) (aarch64-linux-gnu-gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0, GNU ld (GNU Binutils for Ubuntu) 2.42) #6 SMP Thu Feb 19 15:29:56 UTC 2026

Which kernel? Should work on 6.12.y, although I see issues with it on 6.18.y, as there were changes made to that wireless patch set that don't agree with my DTS changes. In fairness, I haven't checked to see if it works at all regardless of my changes on that kernel though. Its on my list of things to investigate. The new DTS changes require an updated hciattach_opi binary. "known to work on 6.12.y" https://github.com/armbian/build/blob/main/packages/blobs/bt/hciattach/hciattach_opi_arm64_upstream

This is what my software stack looks like: My kernel is build as a generic one, hence my OS is working on any device equipped with a VeriSilicon VIPNano, a Rockchip RK3588 or an Arm Ethos-U65/U85 NPU. The application can be written NPU-agnostic, as long as a model.tflite file suitable for the NPU is used.
