Thank you for the response. A constant bluetooth scan is necessary, that is what the application is designed to do - constantly detect nearby bluetooth devices. If your concern is battery drain well we have purchased numerous external power packs which will be able to power this for days. If there is another concern I am not aware with a constant scan please do share.
A single scan does not cause a drop, no. The application I designed calls startDiscovery() every time the discovery is finished (unless manually stopped) to keep it constant. To verify my suspicion that bluetooth discovery was causing the drops I connected the devices via WiFi Direct, navigated to Android's bluetooth settings on the device and manually tapped "Scan" every time it finished. Sure enough one of the connections dropped off after about 8 consecutive scans. I am using a Samsung Galaxy Tab 2 10.1 as the WiFi Direct group owner, and 2 Samsung Galaxy Tab 2 7.0 tabs which should send data to the group owner. The 7.0 devices are running the scans.
