Getting the U2IrDA Mini working is not always plug-and-play because modern operating systems no longer bundle full IrDA stacks. Follow this step-by-step guide.
The U2IrDA Mini is a compact USB-to-Infrared (IrDA) adapter that supports Fast Infrared (FIR) data transfer at up to 4 Mbps. It enables IrDA-capable devices (phones, PDAs, some printers, and legacy equipment) to communicate wirelessly with modern computers that lack native infrared ports. The adapter is plug-and-play on supported systems and is aimed at users maintaining legacy device connectivity or transferring small files and synchronizing settings.
Testing was conducted between two U2IrDA Mini adapters on separate Ubuntu 18.04 hosts, 30 cm apart with 15° alignment.
