Good point.Still has time to answer questions even though they are trying to kick him out of the country.
Bluetooth in the DIAD 4 is used for communicating with an external cellphone that communicates at a different GPRS frequency than the internal DIAD 4 radio. This is currently being used in about 50 centers. The DIAD 4 can also communicate using Bluetooth with a scanner used in the preload. These features were introduced in Sept of 2007.
As far as the DIAD bluetooth it can only be paired with scanner equipped with bluetooth tecnology. You CANNOT pair the DIAD with your cell phone to send info incase your interenal radio goes down. If that happens you can still use a handset and have hte DIAD "talk" to our mainframe over the phone.
