RendezvousInfo is a set of instructions that allows the Device and Owner to find a cooperating Rendezvous Server.  This article documents the steps for connecting to the public fdorv.com Rendezvous Server.

Step-by-step guide

The manufacturing server API accepts RendezvousInfo in the more human readable CBOR Diagnostic form.  The numbers defined in the Diagnostic string are defined in the FDO specification https://fidoalliance.org/specs/FDO/FIDO-Device-Onboard-PS-v1.1-20220419/FIDO-Device-Onboard-PS-v1.1-20220419.html#RVInfo

In order to use the Intel hosted RV server you need to set the manufacturers RvInfo to:

For devices capable of using HTTPS for To1 set to:
[[[5,"fdorv.com"],[3,443],[12,2],[4,443]]]

For devices that need to use HTTP for To1 set to:
[[[5,"fdorv.com"],[3,80],[12,1],[4,443]]]

You can use POST /api/v1/rvinfo/ API to set this in the manufacturer


For Owner/TO0 to work you need to trust the Intel Hosted TLS server certificates or you will get the following error in the logs:
15:07:19.451 [DEBUG] Connection released: [id: 0][route: {s}->https://fdorv.com:443][total available: 0; route allocated: 0 of 5; total allocated: 0 of 10]
…
15:07:19.454 [INFO ] javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
              at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:131)

You can add these certificates to the owner/secrets/ca-cert.pem
