Has anybody got the bluetooth up and running on TB-96AIoT? Any guides?
After reading the documentation coming with the buildroot working directories, I found a bluetooth deviceio_release repo and modified to get it build and run. When selecting its commands 01-open, 94-close, 51-start-ble: repeat 01,94,01,94, … 01 a few times until no more errors, then 51. An android NrfConnect app can see the 96AIoT named ROCKCHIP_AUDIO and can connect to it. But the problem with this repo is that it is only a release repo, no much information as to how you can bring bluetooth up in a normal system without running this binary.
Does anybody know where to find the source repo for “deviceio”?
