We use a WINC1500 on a custom board which also supports an SD-card.
We want to be able to use certificates placed on the SD-card with the WINC1500 / TLS.
Specifically, we need to be able to set the root certificate, such that the WINC1500 can validate the server certificate (signed by the rootCA) when using TLS. Also, we need to be able to set the client certificate when connecting to a server using mutual authentication (such that the server can verify that the WINC1500 is allowed to connect).
Most WINC1500 documentation describe how to set the certificates using a PC (over UART) or HTTP provisioning in AP mode. As explained above, we want to set the certificates from the host MCU over SPI. We found the "programmers_apis", which includes a few functions which seem to support setting certificates over SPI:
However, the documentation is very sparse. Do any of you know of any documentation on this, examples, or have experience using these functions?
Any help you can provide is highly appriciated.
