Firmware modification toolkit for ResMed AirSense and AirCurve devices.
| Platform | Guide |
|---|---|
| AirSense 10 / AirCurve 10 | Air10 Quickstart |
| AirSense 11 / AirCurve 11 | Air11 Quickstart |
| Series 9 | Partial support; no maintained guide |
- Unlocks all therapy modes
- Unlocks clinical settings menu with full pressure range
- Removes motor runtime hours nag screen
- Expands EDF recording across unlocked therapy modes
- Maintains myAir cloud compatibility across therapy modes
- Custom VAuto pressure support in the VAuto slot
- Runtime ASV and ASVAuto backup-rate control
- Selectable Square Wave pressure shaping for S, ST, T, and PAC
- Continuous LCD and button brightness adaptation
- ILI9325/ILI9328 LCD driver (the most common replacement panel available for these devices)
Best support for SX567-0401 and SX567-0402 firmware. Other versions are handled with reduced feature coverage.
- Unlocks supported therapy modes and related clinical settings
- Allows custom ASV and ASVAuto pressure-support ranges
- Expands EDF recording across unlocked therapy modes
- Keeps EDF and myAir variant reporting aligned with the selected mode
- Unlocks configured languages and selected firmware defaults
- Removes the design-life warning triggered after ~20,000 hours of runtime
Windows users can prepare the common build environment with the WSL2 setup guide.
