v1.0.4 -- ISDT Charge Utility

🚀 Changes

• A8 Air:
  • Input Voltage and Total Power are now displayed.
  • IR measurement disabled (unreliable; the ISDT mobile app also does not display an IR value).
• Updated to Bleak 3.1.0 for improved Bluetooth stability.
• Various stability improvements and minor enhancements.
• Added an IR tooltip explaining that measurements are only reliable at charging currents of at least 300 mA.

---

🐛 Bug Fixes

v1.0.3 -- ISDT Charge Utility

🚀 Changes

• None

---

🐛 Bug Fixes

• Intentional disconnects (app shutdown, manual disconnect) no longer trigger
  the automatic reconnect. Only unexpected link losses do.
• IR value will also shown, when state is done

---

📝 Known Issues

• The A4 Air and A8 Air do not operate reliably under Windows. This appears to be related to BLE stack limitations. Linux uses a different Bluetooth stack (BlueZ) which handles the models correctly. The app reconnects automatically.
  My recommendation: buy the C4 Air —it's aworking great !!
