How do I update the firmware of the DJI Mic Mini transmitters and receiver?
Connect the DJI Mic Mini receiver to a phone via a Type-C adapter and update the receiver and transmitters' firmware in the DJI Mimo app.
A DJI Mic Mini transmitter can connect directly to a phone via Bluetooth to complete its firmware update.
When using an iOS mobile device, DJI Mic Mini firmware updates are only supported via Bluetooth, not via USB-C or Lightning connection.
