How to set esp32 to 802.11n?

Hi dear,
After the program adjustment yesterday,the GPIO12/13/14/15 not be used now and the JTAG can normally build breakpoints,Thank you very much for your help these days~

thanks for your help,
regards,

Hi dear,
Pls review the esp-wrover-kit connection as attchment. To enable the JTAG function, I use shorting jumpers on JP8 (JTAG) for TMS、TDO、TDI、TCK、GND.
By the way,the GPIO12、GPIO13、GPIO14、GPIO15 can be reused?I may be use these GPIO to connect Camera.

Hi dear,
The output of OpenOCD as attachment,pls help to review,thanks~

Hi dear, You are right,the OpenOCD process is not running,I run the OpenOCD commend"./src/openocd -s ./tcl -f ./esp.cfg" again,it show"Remote debugging using localhost:3333",but it may be has another question as below: Remote debugging using localhost:3333 Ignoring packet error,continuing... warning...

Hi, I want to use ESP-WROVER-KIT to do JTAG debugging for ESP32,when I OpenOCD,run the command"xtensa-esp32-elf-gdb -ex 'target remote localhost:3333' ./build/app-template.elf",always getting the wrong mesagge"localhost:3333: Connection timed out." What am I missing ? Maybe some access right ? thank...

I use I2S DMA way to collect data from camera. Wifi is connecting,according my investigation,when esp32 collects data from camera ,more or less a pixel occured randomly. I can almost guarantee you its the DMA controller. Same problem of random bytes being changed in the SPI Driver ONLY when used wi...

Hi,dear
Very appreciated your proposal,this problem be resolved this morning,thanks very much~

My first thought would be: what are the impedances on your lines? WiFi drains a fair amount of power and can spread out a fair bit of EMF. If the lines to your camera are too long, not properly specced or otherwise easily influenced, you can get weirdness like this. Wiring is very short, and has ve...
