John,
This functionality is part of the pluggable architecture of CollaboRhythm.
Use ForaD40bHealthActionInputControllerFactory as an example. It is used to support a ForaD40b Blood Glucose / Blood Pressure monitor.
1. Register a HealthActionInputControllerFactory for your device in your PluginModule. In your case, this is the "HypertensionPluginModule"
2. Create this HealthActionInputControllerFactory, which implements IHealthActionInputControllerFactory. One of the methods of this interface is called createDeviceHealthActionInputController. Use some conditional statements to inspect the urlVariables that you send from the AndroidDeviceGateway to CollaboRhythm to make sure that the data coming in is from your device.
3. If the conditions are met, create and return a HealthActionInputController that will determine what to do with the data from your device. This should extend HealthActionInputControllerBase and implement IHealthActionInputController
I can do some team coding with you to get this working today. E-mail me directly to arrange.
