hi: Testing environment: 1、STM32F407 connect serial port to ESP32-WROOM-32D. 2、ESP32 connect router into AT pass-through mode. 3、Set up tcp/ip server. 4、Repeated data sending and receiving. Result: 1、When the serial port baud rate at 115200.The speed only 11KB/s. 2、When the serial port baud rate at ...
Thanks for your reply.My question is i'm not push the button.i still can download the core for the board.But the datasheet say's if you will download core the GPIO0 must be pull down.So i'm confused.
I use the ESP32_Devkitc_V4 development board. Why the board is not in burn mode？I still can download th bootload core.I looked up information for esp32 datasheet. It say when board in burn mode the GPIO0 must be pull-down。So how do i know the GPIO0 status？
