With this app allows the SKG AS3 elevator control (for small goods lifts) read via Bluetooth and configure. In addition, the latest firmware updates can be transferred to the SKG AS3 control (updates can be downloaded directly from the manufacturer server).
For the connection between your phone / tablet and elevator control a Bluetooth stick is required. This Bluetooth stick is simply plugged into the RS232 socket of the elevator control and thus enables wireless access.
