I'm not sure if this is the right forum to raise this, or if it can be passed on to the relevant Bosch developers.
I have been testing an IPv6 only network at home, running in parallel with my dual stack network. Although not common in Australia, I know some overseas ISPs have rolled out IPv6 only networks for customers, so it is important that devices will continue to work.
The Home Connect setup, for a Bosch Dishwasher Serie 6, does not work with IPv6 only network, even with DNS64 + NAT64 running.
* Phone can connect to the Dishwasher
* Transfers WiFi network credentials
* But then just times out with an error it can't connect
The WiFi credentials are stored on the dishwasher, so you need to go into the settings menu and do a factory reset to clear them and be able to start again.
The dishwasher does work on a dual stack network, and does get an IPv6 address.
It has SLAAC based on EUI64 addresses, with the first one displayed on screen (although it gets many). I can ping the addresses -- multiple prefixes, plus the link local. The global address I can ping from external networks.
So, it appears to at least partially support IPv6, but only when running in a dual stack network.
Note that the network is running DNS64+NAT64, so even if the Home Connect server is IPv4 only, the device can still connnect to it. The problem is either a hard coded IPv4 address, reliance on IPv4 only library code, or a code check that assumes IPv4.
