| 9 | 1 | J. Simmons | The HoloSeat firmware has a serial protocol, the Holoseat Serial Protocol (HSP), to enable the desktop configuration app to modify all key parameters and to determine the current configuration of the Holoseat at runtime. It is laid out to mirror the REST API presented to Holoseat clients by the desktop application. |

| 20 | 4 | J. Simmons | |
| 21 | 22 | J. Simmons | Commands are sent as JSON strings with a message ID (may be an empty string, but must be present), a URI, an HTTP verb, and possibly arguments. |
| 22 | 22 | J. Simmons | |
| 23 | 22 | J. Simmons | Note, the Holoseat Python serial library will insert a message ID if none is included. But users interacting directly with the serial port must include at least an empty message ID. This means that the message ID is optional from the app serial monitor and from the app libraries, but not the Arduino serial monitor. |

| 28 | 2 | J. Simmons | |
| 29 | 26 | J. Simmons | The low level commands are intended for development or low level communication use. These commands will not be reproduced in the Holoseat REST API. |
