This app is used to interface with our RFID reader hardware (Joey) developed by our company RFID Race Timing Systems (rfidtiming.com). The interface is via bluetooth BLE (4.2) using a Cypress BLE chip on the peripheral side. The iPhone is the BLE central. The app and Joey use a direct connect serial connection for sharing settings (both read only and read/write). The app is designed to be freely available for users of the Joey system.
