This is the standout specification.

  1. No multi-point: IrDA is point-to-point. You cannot talk to two devices simultaneously.
  2. Line-of-sight required: Unlike Bluetooth, infrared cannot pass through opaque obstacles.
  3. No smartphone support: Modern phones lack IrDA; you cannot “beam” to an Android or iPhone.
  4. Driver fragility: Windows 11 updates occasionally break legacy IrDA stacks. You may need to reinstall drivers.
  5. Speed negotiation: If your target device only supports SIR (115.2 kbps), the U2IRDA will downshift—do not expect 4 Mbps.
