Re: Change I2C clock speed without reinitializing
The way I got arround this same issue was to set up of them instead of just one. Set the parameters for the first one with the fast clk speed, then set the second with the slower one. The trick is to use the same pins for both.

Did you try pulling up IO0?

Re: How to connect the console to a socket
I am using the Console component for a serial command interface but want to also access it remotely. It seems the Console is hard-wired to UART i/o, is it possible to connect it to a network socket? Yes. A while ago I wanted the same thing. So I created a TCP socket server on port 23 (telnet port) ...

Re: 3-Wire-SPI on ESP32-WROOM-32UE
When you initialise your SPI bus. just set the MOSI to -1. // spi_bus_config_t buscfg.sclk_io_num = PIN_NUM_CLK; // GPIO pin for Spi CLocK signal, or -1 if not used. buscfg.mosi_io_num = -1; // GPIO pin for Master Out Slave In (=spi_d) signal, or -1 if not used. buscfg.miso_io_num = PIN_NUM_MISO; //...

Re: Help with PCB project - ESP32 Drone
1) The idea is that the USB will only be used to upload the code and the battery will be disconnected during this time, can it stay like this or should I change something? Then you are ok. 2) I added resistors and capacitors to EN (R21 -> 3.3v, C15 -> GND) and GPIO0 (R20 -> 3.3v, C16 -> GND) looks ...

Re: Help with PCB project - ESP32 Drone
Couple things. #1) I see that VBAT & VUSB are tied together. Not sure your plans, but If the battery is plugged in at same time USB is something bad will happen. #2) I see you have no 0.1uf caps to GND on the EN or GPIO0 lines, Neither pullups to +3.3v. I have seen far to often not doing this typica...

Re: Autodetecting OTA the way the Arduino IDE does
Google the source for Arduino OTA. Thats what I did when I had the same question as you.
Since then I just rolled my own

Re: ESP32S3 files sharing and transfering
Espressif has an example doing this. But its for IDF, should not be any trouble to get it working for Arduino
