Detailed Description
To work with Deepsy mcu service it is necessary to use DeepsyMcuManager located in com.gmv.its.deepsy.mcu for getting the initial McuManager object.
McuManager mcuManager = DeepsyMcuManager.getInstance();
DeepsyMcuManager.getInstance has an optional parameter indicating the ip address of remote service. For instance:
McuManager mcuManager = DeepsyMcuManager.getInstance("192.168.1.10");
In order to finalize properly, it is recommended to call to mcuManager.close();
mcuManager.close();
Examples
Subscribe to GPIO events
Get CAN bus status
