- SDK firmware keeps official AhaKey Studio communication compatibility as a design goal.
- User custom commands should use the reserved range
0xA0to0xEF. - User-built HEX files are custom developer firmware, not official AhaKey firmware.
- Compatibility is based on the current firmware reference and may be updated across future firmware revisions.
