Connection Basics

DynaFamily readers connect to a host over USB or Bluetooth LE. The MMS command set is identical over either transport — how you frame and send commands doesn't change — so the connection choice is about the device and your use case, not your integration code. Wired USB is simplest for fixed, attended setups; Bluetooth LE suits portable and mobile deployments (on the readers that support it, such as the DynaFlex II Go).
