Bluetooth to I2C bridge

Does Sparkfun or anyone else sell a module that allows to send Bluetooth serial commands that get converted to I2C read/write sequences?

Thanks

Thanks for the reply, but it’s pretty terse. Words are cheap, so please feel free to use more.

Do you mean I should program an Arduino to perform this function? What I’m actually looking for is an off-the-shelf module that requires no development, something like the ConnectBlue Bluetooth I2C Bus Adaptor, which I just came across recently (https://www.spezial.com/commercio/datei … 20beta.pdf).

Yep, Ardiuno board then program to do the translation from async serial to I2C.

I seem to recall that FTDI has a chip for USB to I2C but not aware of any off the shelf solution.

Actually, as I said above, ConnectBlue has one. However, I think I’m just going to use a garden variety BT-to-serial bridge and follow it with a PIC or AVR that implements the ConnectBlue message structure.

Thanks
