The document discusses two demonstrations of a Bluetooth broadcast application to share information with nearby mobile devices. The first test at a crafts fair found that 192 out of 338 detected devices had the necessary service and 32 people accepted the shared file. The second test involved a 6-hour trial of the app at a pie shop that offered vouchers to 383 detected devices. Issues identified included file size, naming, and the limited range of Bluetooth. The conclusions were that encouraging Bluetooth use and tweaking the app to target more phones more efficiently could improve outcomes.
