Bullet type identification
I'm managing 4ea Bullet M2 nodes on roofs and towers, so physical access is difficult.
In the past, the type of M2 hardware didn't seem to matter (or i've been lucky), so i don't have records for serial/model numbers.
It seems that the newest version of the firmware has 3 different versions, depending on what type of bullet it is being installed on.

The firmware chart shows:
Bullet M2 Titanium      needs   aredn-
Bullet M2 (XM)            needs   aredn-
Bullet M2 (XW)            needs   aredn-

Our M2 Bullets have whatever firmware came before 3.20.3.
To avoid tower mounted bricks, is there any way to SSH in and ask the router what kind of M2 Bullet it is?

Get the board ID

After SSHing into the device, get the board ID by using the command:


​The result will look something like: 0xe2c4

If board ID = 0xe2c4 device is a Bullet M2 XW
If board ID = 0xe2d2 device is a Bullet M2 Titanium HP
If board ID = 0xe202 device is a Bullet M2 HP

Hardware identification
The hardware identification on the Administration page was added not too long ago.  If they have older software, that method's not available.  The method Randy proposed will work, but you can also access the JSON information page on the node at http://<nodename>:8080/cgi-bin/sysinfo.  That page contains the hardware information, among other things.

OK, thanks all.  i'll try it this week.

Bullet M2 sysinfo page without XM/XW designation?

I've just resurrected a Bullet M2 that likely has a date of manufacture around 2015. The current firmware version is My sysinfo page does not definitively identify it as an XM or XW. Is either firmware update currently offered for the M2 appropriate for my Bullet?

XM.  Two places it identifies as Ubiquiti Bullet M
That is XM.

Are you sure
Are you sure this is an M2 device and not the earlier, unsupported M series device?
Are you sure
The markings on the exterior near the status lights ID it as an "M2", so I'm OK there.
Bullet M2 sysinfo page without XM/XW designation?

That clears up the mystery as to whether the "M" is in-fact designating this as an "XM" unit or not.

I just successfully updated the firmware. Thank you!
