Android Froyo (2.2). Why I cannot put letters on bluetooth PIN? Please, I have a device wich I connect via bluetooth from my Samsung Galaxy S. The bluetooth device have a alphanumeric PIN. When I try connect it ask for PIN but my galaxy only let me to put numbers!. Android 2.1 let me put numbers and letters. Any suggestions? PD: Impossible to change the device's alphanumerical PIN. 

Thank you.

02/02/2011. Question solved. It was as I thought. Update 2.2.1 allow to put numbers and letters in bluetooth PIN(like in 2.1 version).
Looks like its device related issue than Android OS issue.
If its a firmware related issue, vendor may be able to offer you a patch.

Meanwhile if you see an option to switch between Number mode and ABC mode on your keypad, you can try that..

Refer page 29 of device manual.
