Can I make it such that each of the 3 buttons go to each profile?

Is there a way to the first side button activate profile 1, second activate profile 2 and third profile 3, instead of using profile 3 button to alternate between profiles?

I'm afraid I don't know of any way to set the mouse profile programmatically. If you are able to find a way to set the mouse profile programmatically, you might be able to do this with a Gesture detection client such as Easystroke by binding a click to one of the 0x53 or 0x56 (button 8 and 9) to a shell command.

However, this still leaves you with the third button, which does not have a mapping in solaar and I don't think the mouse fires a click event for it. So you won't be able to detect whether it is clicked or not. Further, I don't think you will be able to prevent the default profile rotation behavior from happening, at least I don't know how to achieve this.

TL;DR: I think this is impossible, but I am happily proven wrong on this one!

that's bad, I keep having to look at the mouse to see to which profile it goes. The logitech keyboard K380 has buttons for each profile and I can even deactivate them with a script.

I think the mouse is incapable of doing this, I just tested configuring this with Piper (which I would recommend, as it is far more user friendly than this script :D) and setting the profile programmatically was not possible. Do you know if this is possible in other operating systems?

For someone like me who minimizes things running in the host machine (I only program in VMs) this script is preferable to the complexity of Piper

Hmm, I understand. But still, I don't think the mouse is capable of doing what you want. I also think I misunderstood what you meant with profiles. I thought that you meant the switching between the 2 wifi receivers and the bluetooth mode. Other logitech mice are capable of defining real profiles with buttons mappings and such. The M720 is not capable of doing this. I think you have to get a higher budget mouse for doing such things 😞

[lattice0]

No problem, I think there's no way. Also I think you meant 2 bluetooth receivers + usb dongle. But it looks like I was able to use the 3 profiles for bluetooth, I didn't even use the dongle

[fin-ger]

The M720 has 2 unifying receiver channels and 1 bluetooth channel. I don't know how many USB dongles were shipped with the mouse, but I have several of them here and am actually using both unifying receivers right now 😄

But it looks like I was able to use the 3 profiles for bluetooth

Ah nice! How did you achieve this? Might help others with similar issues.

[lattice0]

I'm very confused, mine came with only 1 usb dongle, and I simply connected to 3 bluetooth devices, I didn't even use the dongle and I don't know how to use it because the 3 profiles are being used for bluetooth

[fin-ger]

Oh wow, you're right. I always thought that it is only possible to connect via bluetooth with the 3rd channel, but I just tried it and was able to connect via bluetooth with all three.

You can use the Solaar tool to pair a unifying receiver with e.g. the 2nd channel and selecting "Pair new device". Now long-press the channel-select-button on your mouse while the channel "2" is selected and you have your mouse paired with a unifying receiver.

Just to be clear: the 3 channels on the mouse are not the profiles you know from other logitech devices (at least as far as I know). Libratbag (the Piper backend) reports that the mouse does not support profiles as well as the logitech homepage is not mentioning any profile support. The 3 modes are 3 different channels to connect to for 3 different devices, e.g. your laptop, PC, and mobile phone.
