This readme is mainly focused on information on how to use the classes in Specialelektronik.Products.Sennheiser.Devices.

You need to add the following reference to you project

SimplSharpNewtonsoft

• When Sennheiser sends error messages, they sometimes have malformed JSON, so they can't be parsed as JSON. Because of that all errors from the devices are return to you as a string with the JSON in it. If you want to act based on an error you have to subscribe to the Errors event of the device and parse the data yourself.

• Clone the repository.
• Open the solution in the SIMPL SHARP directory.
• Build the solution.

Start up your S#Pro project and do the following:

• Add references to the dependencies shown in the Dependencies section of this readme.
• Add a reference to Specialelektronik.Products.Sennheiser.Devices.dll that you built in the steps above.
• The namespace for the library is Specialelektronik.Products.Sennheiser.

The device's properties, methods and events are located in a few different locations. This is completely based on how Sennheiser has decided to do in their protocol. On the root class Chg4N you will find some (see below) but you also the following handlers where you will find more.

• DeviceHandler - Contains things regarding the device. This is found in Chg4N.DeviceHandler.
• BaysHandler - Contains things regarding the charging bays and the devices inserted into the bays. This is found in Chg4N.BaysHandler.

• Connect(string ip) - Opens up the connection to the device. Uses default port 45.
• Connect(string ip, int port) - Opens up the connection to the device.
• Disconnect - Stops the connection to the device.
• Send(string data) - Used as a way to send your own commands. Refer to the Sennheiser Sound Control Protocol (SSC). Example command: {"device":{"reset":true}}.
• Send(object value, params string[] path) - Used as a way to send your own commands. An example would be Send("name", "device", "location").
• Dispose() - Used to clean up timers and connections. This must be called when your program stops.

Located in Chg4N.DeviceHandler.

• PollInfo() - Asks the device about Version, Serial, Product and MacAddresses. This is automatically done on connection, so your should not need to do this manually.

• IsResponding - Returns true as long as the device is responding. As the protocol uses UDP there is no connection state, so it might take up to a minute before responding goes low after the device has stopped responding. Listen to the Responding event to know when this changes.
• Debug - Enables debug messages to be printed to the text console while set to true. Make sure this is not left on when not used.
• DeviceHandler - Returns the device handler, where you have features, properties and events regarding the device.
• BaysHandler - Returns the bays handler, where you have features, properties and events regarding the charging bays and the devices inserted into the bays.

The device's properties, methods and events are located in a few different locations. This is completely based on how Sennheiser has decided to do in their protocol. On the root class Sldw you will find some (see below) but you also the following handlers where you will find more.

• DeviceHandler - Contains things regarding the device. This is found in Sldw.DeviceHandler.
• RxHandler - Contains things regarding the receiving end, such as RF quality. This is found in Sldw.RxHandler.
• TxHandler - Contains things regarding the transmitting end (the microphone or bodypack), such as battery level. This is found in Sldw.TxHandler.
• AudioHandler - Contains things regarding the receiving end, such as Output gain and EQ. This is found in Sldw.AudioHandler.

• Connect(string ip) - Opens up the connection to the device. Uses default port 45.
• Connect(string ip, int port) - Opens up the connection to the device.

This will also cause the Sldw.RxHandler.Events event to trig whenever there's a change. The reason you have to manually enable this is because the device is quite ”chatty” so if you don't use this feature all that traffic is unneccesary.
• DisableRfQualityFeedback() - Disables the RF quality feedback (see EnableRfQualityFeedback()).

• IsResponding - Returns true as long as the device is responding. As the protocol uses UDP there is no connection state, so it might take up to a minute before responding goes low after the device has stopped responding. Listen to the Responding event to know when this changes.
• Debug - Enables debug messages to be printed to the text console while set to true. Make sure this is not left on when not used.
• DeviceHandler - Returns the device handler, where you have features, properties and events regarding the device.
• RxHandler - Returns the RX handler, where you have features, properties and events regarding the receiving end, such as RF quality.
• TxHandler - Returns the TX handler, where you have features, properties and events regarding the transmitting end (the microphone or bodypack), such as battery level.

The device's properties, methods and events are located in a few different locations. This is completely based on how Sennheiser has decided to do in their protocol. On the root class Tcc2 you will find some (see below) but you also the following handlers where you will find more.

• DeviceHandler - Contains things regarding the device. This is found in Tcc2.DeviceHandler.
• MeterHandler - Contains things regarding meters, such as azimuth, elevation and input peak level. This is found in Tcc2.MeterHandler.
• AudioHandler - Contains things regarding the audio output, such as Dante Output gain and Mute. This is found in Tcc2.AudioHandler.

• Connect(string ip) - Opens up the connection to the device. Uses default port 45.
• Connect(string ip, int port) - Opens up the connection to the device.
• Disconnect - Stops the connection to the device.
• Send(string data) - Used as a way to send your own commands. Refer to the Sennheiser Sound Control Protocol (SSC). Example command: {"device":{"reset":true}}.
• Send(object value, params string[] path) - Used as a way to send your own commands. An example would be Send("name", "device", "location").
• Dispose() - Used to clean up timers and connections. This must be called when your program stops.

Located in Tcc2.DeviceHandler.

• PollInfo() - Asks the device about Version, Serial, Product and MacAddresses. This is automatically done on connection, so your should not need to do this manually.

Located in Tcc2.MeterHandler.

The reason you have to manually enable some feedback is because the device is quite ”chatty” so if you don't use those features all that traffic is unneccesary.

• EnableAzimuthFeedback() - Enables subscription to Azimuth degrees feedback. When enabled the Tcc2.MeterHandler.AzimuthDegrees property will be continuosly updated. This will also cause the Tcc2.MeterHandler.Events event to trig whenever there's a change.
• DisableAzimuthFeedback() - Disables the Azimuth degrees feedback.
• EnableElevationFeedback() - Enables subscription to Elevation degrees feedback. When enabled the Tcc2.MeterHandler.ElevationDegrees property will be continuosly updated. This will also cause the Tcc2.MeterHandler.Events event to trig whenever there's a change.
• DisableElevationFeedback() - Disables the Elevation degrees feedback.
• EnableInputPeakLevelFeedback() - Enables subscription to input peak level feedback. When enabled the Tcc2.MeterHandler.InputPeakLevelDb property will be continuosly updated. This will also cause the Tcc2.MeterHandler.Events event to trig whenever there's a change.
• DisableInputPeakLevelFeedback() - Disables the input peak level feedback.

• IsResponding - Returns true as long as the device is responding. As the protocol uses UDP there is no connection state, so it might take up to a minute before responding goes low after the device has stopped responding. Listen to the Responding event to know when this changes.
• Debug - Enables debug messages to be printed to the text console while set to true. Make sure this is not left on when not used.
• DeviceHandler - Returns the device handler, where you have features, properties and events regarding the device.
• MeterHandler - Returns the meter handler, where you have features, properties and events regarding meters, such as azimuth, elevation and input peak level.
• AudioHandler - Returns the audio handler, where you have features, properties and events regarding the audio output, such as Dante output gain and Mute.
