Question Bluetooth pen with replaceable or refillable ink cartridge creating corresponding LaTeX script ?

[DynV]

Can you suggest a Bluetooth pen with replaceable or refillable ink cartridge that I can use both
* for writing on paper, and
* with the cap on or pen tip retracted (the latter if retractable),
both recognizing the formula and creating the corresponding LaTeX script? I don't have a large budget but if an expensive pen has great advantages over a cheap one, I'll consider it. Preferably using a standard battery, eg SR621SW & AG1, so no need to solder if the rechargeable battery was to die.

Thank you kindly for your help

Something like this stylus product that would contain real ink as well?

Keep it simple: just use the bluetooth pen as a stylus as intended. Forget ink inside.

Then just keep a couple of regular ink pens handy for when writing with ink is required.

One "pen" doing both is likely to be cumbersome and a failure could leave you with little or no writing/drawing capability.

I understand the possible convenience of a combined stylus and ink pen. However, likely to be cumbersome and who knows what may happen with respect to being able to get replacement in cartridges, etc..

Remember Occam's razor.

Yes; although I have no Apple product; so Windows, Ubuntu & Android. It could even switch tips, an ink one and a pressure-sensitive one, but both able to extract the LaTeX from.
