在ESP32上使用PlatformIO进行开发时,垃圾串行输出(Garbage Serial Output)通常指的是在串行通信过程中出现的意外或不正确的输出数据。这可能是由于硬件连接问题、代码错误、通信速率不匹配等原因导致的。 为了解决垃圾串行输出问题,可以采取以下步骤: 检查硬件连接:确保ESP32与串行设备(如计算机或其他设备)之间的连接
When setting CPU frequency below 80Mhz, the serial monitor is garbage until I change the baud rate... I manage to solve the problem by setting the Serial.begin(bauds) to : 80 / cpufreq * monitor_bauds See sketch attached. Sketch ...

I have implemented Watchdogs and 24Hours soft restart (ESP.restart()), but none of this is helpful in my case. I would like to know if there is any issue with esp32-wroom-32e. When I receive a completely frozen unit, it is printing some garbage value in the serial monitor and Blue...
