Revolutionizing Pocketable Audio Recording: DJI’s Latest Firmware Update
DJI, the leader in aerial photography systems, has released a significant firmware update for the DJI Mic 2, marking another stride in audio recording technology.
As of January 31, 2024, firmware version v04.03.08.31 is available, bringing a host of new features and fixes to enhance user experience.
Key Features of the Update
- Transmitter Auto Off: This new feature, which is enabled by default, ensures that the transmitter automatically shuts down after 15 minutes of inactivity when not connected to any device and without independent recording.
- Noise Reduction at Your Fingertips: Users can now enable or disable noise reduction simply by pressing the power button, a feature that is activated by default.
- Enhanced iPhone 15 Series Compatibility: The update allows the receiver to be used while charging, particularly when connected to an iPhone 15 via the mobile device adapter.
- System Stability Optimization: The firmware enhances overall system stability during usage.
- Critical Fixes: The update addresses and resolves specific issues, including a bug where the transmitter couldn’t switch to Bluetooth mode during internal recording and incorrect LED indications when directly connected to a Bluetooth device.
Updating Instructions and Notes
To ensure the best performance, users are advised to update their firmware by following these steps:
- Download the firmware from the DJI Mix 2 product page.
- Connect the transmitter or receiver to a computer using the USB-C cable provided. Note that the receiver should be off, and the transmitter can be in any state.
- Place the .bin file of the firmware update in the root directories of the devices.
- After disconnecting, the receiver updates automatically, displaying “updating” on-screen. The transmitter, once powered on, also updates automatically.
- Post-upgrade, users can verify the successful update by checking the firmware version on the receiver.
In case of update failure, DJI recommends re-downloading the firmware and repeating the steps. If the transmitter doesn’t update automatically, users should disable Auto Record on the receiver or manually stop the transmitter’s internal recording.
