          Not sure I follow this dialog as it looks like a cut and paste from a separate email dialog.

           

          For testing SPI, we have an application within the SDK that includes a Windows peer application: /WICED-Smart-SDK/Apps/spi_comm_slave

           

          This application initializes the second SPI interface on the BCM2073XS to communicate with the peer device as a SPI slave.

           

          There is also a /WICED-Smart-SDK/Apps/spi_comm_master example, but it does not include a companion Windows peer app.

           

          This application essentially initializes the second SPI interface on the BCM2073XS to communicate with the a peer device as a SPI master.

           

          Not clear on the inferences to Wahoo.

           

          The customer would need to buy an eval board (or sample from a distributor) and look at the documentation to determine both design options and speed tradeoffs (the second SPI is 6MHz).

           

          ACKme also has their Bobcat board which leverages our BLE device. userc_6124 can help you with the Zentri solution.
