This page describes how to talk to a GIMX instance that is listening for UDP packets on a specific port.
See the "--src IP:port" argument on the Command line page to learn how to start such a GIMX instance.

Protocol starting from version 7.1
One problem with the earlier protocol was that backward compatibility was broken each time a new axis was added to the controller map.
The new protocol allows to send any number of axis values.
Get controller type
Use this request for getting the controller type of the remote GIMX instance.

Use this request to update the axes of the remote GIMX instance.
The Controller Maps page describes the axes and the value ranges corresponding to each controller type.
byte | value | ||||||||||||||||
0 | 0x01 | ||||||||||||||||
1 | number of axes to follow | ||||||||||||||||
2 |
| ||||||||||||||||
3-6 | axis value (network byte order, see below) | ||||||||||||||||
... | repeat 2 and 3-6 for each axis to update |
To compute the axis value, take the int value stored as two's complement, and store it using the network byte order, which is big endian.
Examples:
- -32767 = 0xffff8001 => value = 0xff, 0xff, 0x80, 0x01
- -127 = 0xffffff81 => value = 0xff, 0xff, 0xff, 0x81
- -1 = 0xffffffff => value = 0xff, 0xff, 0xff, 0xff
- 0 = 0x00000000 => value = 0x00, 0x00, 0x00, 0x00
- 1 = 0x00000001 => value = 0x00, 0x00, 0x00, 0x01
- 127 = 0x0000007f => value = 0x00, 0x00, 0x00, 0x7f
- 32767 = 0x00007fff => value = 0x00, 0x00, 0x7f, 0xff
Protocol for versions up to 6.11
Get controller type
It's possible to send a packet to get the controller type from the remote GIMX.
byte | value |
0 | 0x11 |
1 | 0x00 |
byte | value |
0 | 0x11 |
1 | 0x01 |
2 | value |
value | type |
0x00 | JOYSTICK |
0x01 | 360 PAD |
0x02 | SIXAXIS |
0x05 | DS4 |
0x07 | T300RS PS4 |
0x08 | G27 PS3 |

All axes are signed integers.
The Controller Maps page describes the axes and the value ranges corresponding to each controller type.
byte | value |
0 | 0xff |
1 | 0x9C = 156 |
2-5 | axis 0 |
6-9 | axis 1 |
... | |
158-161 | axis 39 (changed in GIMX 6.10) |
