I’m sorry for the delayed response. I’ve been away for the New Year holidays.
I have generated the new netcfgInstanceId , change it in my inf file and my filter driver is properly installed but it is connected with another machine and not able to communicate with each other.
Besides changing netcfgInstanceId in INF file you also have to change it in common.h and rebuild the driver from the source code. Have you rebuilt the driver?
And again, your manipulations with Characteristics value are incorrect.
