Trying to Connect Wp608 with Android Mobile

Hi,
I want to communicate WP7608 Sierra modem module with Android Device.
Wireless modem mounted on development PCI board and connected with Mobile through OTG cable.
While communicating, I am able to detect the Modem module but not able to connect. Can you tell me what is going wrong..

Note: The dev board is working fine with Laptop (Windows/Ubuntu)

Thanks in advance

Android uses RIL driver to communicate with modems.
You need to contact distributor to get the RIL driver for wp76 module
