Keyboard connector layout

[gweber]

My cosmo died, and my wife gave me a Samsung S24 phone. But I miss the keyboard, só I intend to build a circuit to turn Cosmo's keyboard into a Bluetooth portable keyboard. I can program an Arduino to discover the keyboard's connector layout, but, just in case, does anyone already did this?

I have not done this but previously used RasmusB's adapter to usean old Psion 5MX keyboard with my Note 10. I'll love to reuse my cosmokeyboard with my new S24 Ultra. If you figure this out, please let us know.
