Re: internet unavailable when connected to AP(Wi-Fi) of ESP32 DevKit,

https://github.com/espressif/esp-idf/blob/master/components/lwip/apps/dhcpserver/dhcpserver.c?#L355 Since I could only set DNS to 0.0.0.0 and that didn't work for Android I also commented out the 13 lines from the link and then in Windows no IPV4 DNS servers are shown. Gateway also not shown. Not s...

Re: internet unavailable when connected to AP(Wi-Fi) of ESP32 DevKit,

Interesting about the Garmin device. What device is it? Does it prevent hijacking the internet connection on both iOS and Android? Here's what I have after struggling with this as well. It seems to work for iOS, but not always working in Android. this is in main() before initializing WiFi: tcpip_ad...

Re: CAN vs OTA: interrupt watchdog timeouts despite delay in OTA and IRAM_ATTR in CAN

Yes it has been working in production for 9 months without problems. I think I just made the changes listed but so much has happened since.

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...

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

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.

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

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.
