Re: List of known bugs

There are a lot of issues! If you find the "search for bugs affecting me" button, let me know, I've been looking for it as well :) But if you search for just "bugs" they are reduced to 4 open ones and 49 that are closed. If you're looking for changes from IDF version to IDF version check out the rel...

Re: app-flash and ota

Thanks, Mahavirm, excellent answer! Have to admit that I am lazy and was looking for a single command or, better yet, keyboard shortcut in `monitor`. Maybe I'll try my luck at putting that together. I think I'll experiment with leaving out the factory partition enitrely. From the docs it sounds like...

app-flash and ota

Is there a hidden option (aka "something I overlooked) to use use `app-flash` when using ota partitions? Background: I'm using `idf.py app-flash` / `Ctl-T Ctl-A` in the serial monitor during development to speed up firmware flashing. Unfortunately, when I'm testing OTA, `app-flash` flashes to the `f...

Re: How can I build C project without FreeRTOS?

While I agree with the general sentiment that you are almost certainly better off using the IDF for anything productive, I would be interested in seeing a "bare-metal" example if only to understand the build process better... I assume it would be as easy as using the xtensa- tools to build, link and...

Re: Try wifi ssid and password before connect

You would try to connect in APSTA mode and if you see a successful WIFI_EVENT_STA_CONNECTED event you can turn off the AP.

It's a location that falls somewhere in the ROM of those chips. It points to a random set of 4 bytes of code that simply happens to be different for each of the chips.
Fantastic! :lol: That never occured to me! D'oh. Very simple and pragmatic solution... Thanks, you made my day!

Serial Bootload - Chip Detection - Documentation

I'm playing around a bit with serial communication with the bootloader and I'm wondering whether I'm missing a crucial bit of documentation, specifically where the CHIP_DETECT register is described ... After connecting to the bootloader, esptool (and others) read register 0x40001000 (named CHIP_DETE...

Distributing Full Firmware Updates

Is there an obvious mechanism I'm missing to distibute a complete update for an ESP32? I.e. one that contains all contents that would get transferred by `idf.py flash`? Upates to the partition table, etc. Otherwise OTA would be sufficient. There are two use cases that come to mind: - we need a field...
