A wifi serial port passthrough problem

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 ...

Re: a questions about burn mode

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.

a questions about burn mode

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?

关于烧录模式的问题

为什么我使用开发板ESP32_Devkitc_v4,进行开发,不将GPIO0拉低也能烧录?这样我如何能识别此时GPIO口的状态?始终在高的状态?

Re: EP32首次烧录问题

搭建下环境,然后连接电脑烧录。无论使用flash_download_tools还是msys32均可,环境搭建教程网上很多

关于烧录模式的问题

本人萌新,新入手ESP32_Devkitc_V4开发板研究。但是通过msys32或是flash_download_tools,进去烧录时,按照datasheet中说明GPIO0需要下拉才能进入烧录模式,为什么我并未对板子进行下拉却能成功烧录,想问下各位有这种情况吗?如果不是使用开发板使用ESP32模块我如何去识别此GPIO0处于何种工作模式呢?因为无论如何上拉均可以烧录。
