The data had to be transmitted over WiFi. At first TCP/IP was being used with mixed results. Connection wouldn't be successful, there was lag or data would be lost. On the same Arduino Forum it was suggested to pack the data from the accelerometer as OSC messages and use the mrpeach library in Pure Data to unpack them and then process them. 

A drawback was the connection of the WeMos to a Network. Eventually it was possible and the transmission started as OSC messages.
