We are interested in using the Silex SX-UPAN board which utilizes the Qualcomm QCA4004 WiFI module. I asked them about documentation for the commands for SPI interface and they referred us to the Qualcomm developer netwrok. However, I have been unable to locate the required documentation. All I can find is the documentation for your API library and SDK, not the documentation to talk directly to the QCA4004. We need to find the information to write an API library not how to use Qualcomm SDK.
Can anyone point us in the right direction to locate this documentation?
