Abstract: A wireless adapter and method of using the adapter for wireless connection via communication protocols, communication and data exchange between non-master peripheral devices that have legacy interface such as legacy wired serial computer interfaces and computing devices. The wireless adapter includes a wireless module such as a radio transmission/reception module that supports one or more wireless interfaces and has embedded software stack with at least one or several communication protocols. The wireless module is connected to a microprocessor emulating role of a master device. The adapter interface connector plugs into the legacy interface connector of the non-master peripheral device. The microprocessor emulates a master device in legacy interface in combination with a voltage regulator/converter so the wireless adapter plays a role of a master device in legacy interface with the non-master peripheral device acting as a non-master device in interface.
