New

  • Japanese / Korean Layout Key Support: Added support for Japanese and Korean layout-specific keys, improving compatibility for JIS and KR layout users.
  • Independent 2.4G Transmission for Left Half: Added an independent 2.4G transmission channel for the left keyboard half, improving receiver communication and reducing interruptions during wireless input.

Improved

  • Wireless Connection Stability: Improved communication stability between the left and right keyboard halves, helping reduce missed inputs, delayed responses, and right-side unresponsiveness.
  • 2.4G Receiver Reliability: Optimized 2.4G receiver communication and error handling for more reliable input performance.
  • Bluetooth Input Stability: Improved BLE input handling to reduce input lag, stuck key behavior, and occasional unresponsive input after reconnecting.
  • Key Release Detection: Improved key release recognition across Bluetooth and 2.4G modes to reduce the chance of keys feeling “stuck” after being released.
  • Wake-Up and Reconnection Behavior: Improved wake-up behavior after sleep or reconnection, helping the keyboard respond more reliably when returning to use.
  • Power and Radio Management: Optimized wireless radio behavior to improve stability and reduce conflicts between Bluetooth and 2.4G communication.

Fixed

  • Bluetooth Reconnection Input Issue: Fixed an issue where input could become unresponsive or delayed after reconnecting through BLE2 / BLE3.
  • Bluetooth Report Loss: Fixed an issue where keyboard or consumer control reports could occasionally be lost after a Bluetooth send failure.
  • 2.4G Input Loss: Fixed an issue where single-packet transmission failures could cause missed keystrokes in 2.4G mode.
  • Media Key Reliability: Improved multimedia key release behavior to reduce the risk of media keys becoming stuck.
  • WebUSB Receiver Commands: Fixed an issue where receiver DFU or re-pairing commands could still return “OK” even when the command failed.
  • Accidental Key Press Detection: Reduced the chance of accidental press detection during Bluetooth key testing or wake-up scenarios.

Note for macOS Users

When dragging a firmware file into the NocFree & drive, some macOS users may see a Finder pop-up saying that the operation cannot be completed because certain data could not be read or written. This may appear as Error Code -36.

This may happen during the firmware update process when the device reconnects automatically. Please don’t worry — this does not necessarily mean the update failed.

Please continue dragging all 3 firmware files one by one in the instructed order. After completing all steps, open NocFree Link and check the firmware version.

As long as NocFree Link shows Firmware Version: 2.1.0, your firmware update has been completed successfully.
