Re: Error while running wifi code

Can you post your code? Just an error dump is not that useful if we don't know what your code tried to do.

Re: ESP32 Wrover can't upload the firmware anymore

I think your caps lock key may have some issues, as the title of your post was all-caps. I took the liberty to make it lower-caps.

Re: I2C fails when BT Classic SPP starts receiving

You may want to clean up your code first... it's a PITA to waddle through lots of commented-out code, and you're also missing some critical stuff (where is the MPU code for example?) 'i2c number error' is the error the I2C driver gives you when the integer indicating I2C master 0 or 1 is out of rang...

Re: Can't figure out how to stop bootloader WDT

Obvious question: why is the wdt triggering in the first place? Do you use a custom bootloader?

Re: ESP32 i2c_driver_install error

Your config struct is on the stack so it may contain crap in the members you don't initialize. i2c_config_t conf={0}; in line 1 should fix that.

Re: Save Website as .jpg with ESP32

You could use a server-side library that can draw charts... maybe even use the Google chart thing in a Node.js environment on your server or something, but to be honest, that's a bit out of my area of expertise.

Re: ESP32 Pinouts

Erm, what boards in particular are you talking about? There are a gazillion things that can be qualified as 'boards with esp32 on it', and the pin count doesn't really help.

Re: Save Website as .jpg with ESP32

I don't think that will work. Google Charts will generate this PNG using the Javascript on the page that runs... in your browser. No browser means no Javascript execution means no PNG.

Re: Save Website as .jpg with ESP32

With an ESP32? Not really. In order to render any website, you'd have to parse the HTML, CSS, javascript, download the images, etc. Look in task manager (or your OSses equivalent) how much memory your browser uses and try to imagine if that would fit in an ESP32, either with or without 4MiB of PSRAM...

Re: Power consumption - especially if not everything is working smooth

Effectively, what happens when an ESP32/ESP8266 does when its power is too low is undetermined: as the logic is not working within its normal parameters, anything can happen, including high current drain. You probably want to have a chip that keeps the ESP in reset when the power is too low; chips l...
