The easiest way to check which firmware version your BitBox01 is running is to open the BitBoxApp, then go to "Manage Device" where you will see the firmware version.
If that is not possible for some reason, see the instructions below:
On Mac:
- Plug your BitBox01 into your Mac.
- Open Terminal and run this command: ioreg -p IOUSB -l -w 0
- Look for "Bitbox" entry and find the "USB Serial Number".
Example: "USB Serial Number" = "dbb.fw:v7.1.0" => The firmware version is 7.1.0
On Linux:
- Plug your BitBox01 into your Linux computer.
- Open the command line and run this command: lsusb
- Look for "Bitbox" entry and similarly to Mac instructions above look for an entry that contains the firmware version.
