Hello,
Please check this thread: How to mount /lib/firmware RW
Firmwares are located in /lib/firmware
on the host os.
BalenaOS does not ship the /lib/firmware/rtl_bt/rtl8761a_fw.bin
file.
You’ll need to:
- get that firmware from somewhere, this debian package for example https://packages.debian.org/en/sid/firmware-realtek ;
- copy it to your container;
- follow the thread linked above to bind-mount
/lib/firmware
in the container; - on runtime in your container, re-mount the bind-mount from above rw and copy the firmware in it.
