Bare Bluetooth Keyboard chips.. Recommendations?

Lol, if you have an iPad, and the USB camera connection kit,
it also works with wired USB keyboards right out of the box.. totally undocumented.
Some keyboards fail because they require too much power.

I had a look at the data sheet, oh my, I think for a one-of project it would be simpler
to destroy the smallest bluetooth keyboard I can find.
There is an IC about that can make the keyboard switch connections directly,
I think it's called a lateral switch, and an IC has ten of them.

It might pay to just connect the numeric keys and enter, and just send all data as one checksummed slab of numeric data.
If I make this thing, it will end up a rather large GPS. The GPS is a serial GPS mouse that requires power.

Hi Art. I'm not interested in starting a platform war here, but if you are keen to develop apps, particularly with custom hardware, you might find Android less painful as the platform is pretty much completely open. I programmed a PIC to measure temperature with a DS18B20, send serial data to a VERY cheap RS232 Bluetooth adapter, receive and display on my phone with an app I wrote... all in just a couple hours, and everything done in Basic. The iPhone is cool and was the first in the space, but there is little to distinguish the platforms today, other than openness (and cost). You might want to have a look at least, and come to your own conclusion.

It is my intention to write for both,
but right now I'm already committed, and have apps in their app store.

This project is just a little thing for me personally.
