can i use a bluetooth mouse with ipad

That is called buying the right tool for YOUR needs. It doesn't mean it is best for everyone else, particularly those who worry about security.

No, you buy an Android tablet that not only allows you to add a blue tooth keyboard folio and mouse, it also allows you to add memory via an SD card.

I will pass thank you, I am concerned with security on my devices, I don't need a mouse on a tablet for what I do and I don't need to have a memory slot which adds yet another place for moisture to get in and relies on a non-secure filing system to work. But if that does meet YOUR needs more power to you. Glad you like it.

Just to keep people informed. If you are an Enterprise user and have an iPad, like I do and sometimes need to remote into work (I do often when travelling), you can use the Citrix X1 mouse for all Citrix sessions on an iPad (even done it once off my iPhone but that was bad admin on power by me).

So it is possible, it is available but just not natively.

You are missing the point here...the wireless bluetooth mouse support isn't for the iPad layout use. Let me explane more...I want to use a mouse with e.g. "Teamviewer" app.When the app is running and connected to a Windows PC/ Laptop you have the cursor waiting. So why not having a mouse to move it around and use it as a regular mouse only over the running app??

Could you test if this mouse works with Teamviewer app??

Teamview does have a virtual mouse as well. There are flaws with iPad and teamview working together though, Even with a keyboard case you often have to activate the virtual keyboard to get your actual keyboard to work. It seems random. Sometimes I can remote in with Teamviewer and start typing right away, other times I have to bring up the menu and then screen size is reduced. The missing ability to use a mouse is a joke, using a fat finger on a remote's microsized screen, you often hit the wrong line. A work around is I bought a very fine point stylus and use that instead but it gets tiresome when you have to hold it up on a vertical screen rather than slide it on a desktop. At the start of this thread I read that Apple want's to alter the behaviors of the user rather than alter the equipment to the user's needs. That is very disturbing.
