Helo,

I have made hardware. Commands works from Arduino Ide Serial Monitor (on PC and RPI). I can't connect from Ekos with Xagyl wheel driver. System is Raspberry pi 3B.

: Connecting to /dev/ttyUSB1 @ 9600
DEBUG 22.912000 sec : Port FD 3
DEBUG 22.912213 sec : Connection successful, attempting handshake...
DEBUG 22.912324 sec : CMD <I1>
ERROR 54.930461 sec : I1: Timeout error.
INFO 54.930725 sec : Error retreiving data from XAGYL Filter Wheel, please ensure filter wheel is powered and the port is correct.
DEBUG 54.930860 sec : Handshake failed.

There is no response for I1 command. In ino code firmware version is "FW3.1.5." Any clue ?
