 ## Services (.srv)
 * [Empty.srv](srv/Empty.srv): A service containing an empty request and response.
 * [SetBool.srv](srv/SetBool.srv): Service to set a boolean state to true or false, for enabling or disabling hardware for example.
+* [SetFloat32.srv](srv/SetFloat32.srv): Service to set a float32 value, for setting a numeric threshold or gain for example.
+* [SetInt32.srv](srv/SetInt32.srv): Service to set an int32 value, for setting an integer mode or counter for example.
+* [SetString.srv](srv/SetString.srv): Service to set a string value, for selecting a profile or a configuration name for example.
+* [SetUInt8.srv](srv/SetUInt8.srv): Service to set an unsigned 8-bit integer value, for setting a small command code for example.
+* [SetUInt8Array.srv](srv/SetUInt8Array.srv): Service to set an array of unsigned 8-bit integer values, for sending a compact payload for example.
 * [Trigger.srv](srv/Trigger.srv): Service with an empty request header used for triggering the activation or start of a service.
