Re: Question to people wanting CanBus in the next chip version

Existing systems in cars. I would not use CAN for a fully owned system as it is neither fast or cheap. Ethernet is so well supported generally with commodity hardware. Some new BMWs now have in the teens of ethernet nodes, but apart from between the gateway and OBD port it is 2 wire 100Mbps develope...

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

S2 improvements to the dual core ESP32 whilst retaining CAN would be awesome. I don't want an SPI CAN controller for size and latency, the ESP32 is awesome for CAN.

The main S2 improvements I want are the ability to address larger flash and PSRAM.

Re: ESP32: Partition Table Update through OTA

My changes were for updating factory and choosing which app to boot. I worked through the errors/barriers one at a time making changes and adding other features. For your changes I would think you need a running app from which you can reprogram the partition table and bootloader, making sure you hav...

esp_https_ota and bootloader are the components I copied from esp-idf to my project's components directory. Then started editing.

Re: ESP32: Partition Table Update through OTA

There has been discussion on how to flash the factory app from OTA app. Maybe you could do similar to flash the partition partition. Might need to look at CONFIG_SPI_WRITING_DANGEROUS_REGIONS_* in sdkconfig too.

Re: Does the ESP32-EVB have some LEDs that I can control ?

I switched one on which also operated the relay to show when my software was running normally. The visual and audible confirmation was useful, but I chose not to send high frequency LED flashes on this pin on this board, but I was only using ESP32-EVB for initial testing.

Re: Verify WLAN Password in SoftAP mode?

Use APSTA. When the ESP32 channel hops to connect as STA, connection to AP may be interrupted briefly. Same with scanning, so I display "Wait 5s" in the button the user clicked and then reload the page for both operations as found it a smoother user experience.
