ESP IDF 3.3 with "old" modules, new production run uses v3 modules - updates and compatibility

I have devices in production using WROVER modules with 16MB flash and 8MB PSRAM using ESP IDF release 3.3 using a different toolchain as per github https://github.com/espressif/esp-idf/issues/2892 to mitigate PSRAM issues which seems to work well. The next production run has the new v3 modules. I wa...

CAN is a bit of a... thing. I won't say we have a CAN controller in our chip (because of ...reasons), but I can say that the ESP32-S2 has a peripheral we call the 'TWAI (Two Wire Automotive Interface) controller'; which happens to be fully compatible with the peripheral you used to use for that on ...

Re: What would you like to see in The Next Chip?

Is it possible to say whether CAN bus is intended to be included in future chips? If CAN has been removed from plans for future designs that would be really helpful to know too.

Re: AWS S3 - root certificate changing

I don't have any experience with an actual certificate changeover, but my experience with concatenated PEM files and the existing AWS / ESP-IDF library code is that they seem to work fine, so I would expect that you could put both certificates in a single concatenated PEM file and you would be able...

Re: AWS S3 - root certificate changing

Can certificates be concatenated and either one expected to work when the certificate on the server is changed?

Re: AWS S3 - root certificate changing

I have Amazon Root CA 1 already stored, I just need to work out how and when to use it instead of Digicert, or how to allow either to be used. Any suggestions welcome.

APSTA - time before network shows in Windows

What settings (if any) might influence the time it takes for the AP to show in Windows or Android when they scan for networks? It can take a few seconds to appear even when the ESP32 has been powered for a while.

ESP IDF 3.3.
