Inventop has updated its messaging software for Bluetooth-enabled PDAs, ProximityMail, to version 1.4.

According to the company, ProximityMail now supports HewlettPackard's full iPAQ line of Pocket PCs with either built-in Bluetooth (the new iPAQ 5450) or BrainBoxes BlueTooth Compact Flash cards.

In addition, Iventop said ProximityMail 1.4 features new capabilities, including improved device discovery and an increased data exchange limit to 100k. CEO.

Iventop said ProximityMail turns PDAs into a localized community-messaging network, which enables peer-to-peer networking and expanded Bluetooth effective range beyond 10 meters. The company said its BluePing Network technology is compliant with the Bluetooth 1.1.

The company claims ProximityMail facilitates community building, professional networking, and relationship building wherever groups of people are gathered (eg. tradeshows, conferences, ballgames, political events, etc.). Users can create and subscribe to groups, broadcast or send private messages. It allows users to communicate anonymously to groups of users, without knowing a specific user's PDA id, phone number or email address.

When ProximityMail is installed on a Bluetooth-enabled PDA, Iventop said the PDA acts like a network repeater, pinging other devices, establishing network connections, and transmitting network data as required. The PDA doesn't even have to be powered on.
