UHF SDK/Demo application for WAP4

Hello,

 

I am working on a WAP4 with Windows Mobile CE 6.5 and have WA9901 module installed for RFID tag detection. The inbuilt demo application works fine, and thus the module is installed properly and operational.
I am trying to develop an application in .NET to detect the RFID tags but I cannot find the Driver or any SDK for UHF modules. All I get on the website is SDK and drivers for LF and HF.

 

Can anyone please help me with the drivers for UHF and also the SDK or a DEMO application

 

Thanks,

Parth
