I'm getting my ESP32 into a mode where an esp_now_send returns 12393, which, in turn, esp_err_to_name() tells me is an UNKNOWN ERROR. At the sime time something seems to have clogged esp_now, as no messages are going out. Unfortunately this is extremely hard to debug, so ...

esp_ota_end报错ESP_ERR_INVALID_ARG,一、前提知识1、寄存器空间和内存空间是两个不同存储部分,程序指令和栈一般认定在内存中,而寄存器可以存储数值和某些内存空间地址。2、栈空间是由高地址向低地址增长的,栈顶就是地址最低的。3、ESP寄存器往往存储栈顶地址,是动态变
The problem is that esp_light_sleep_start() returns ESP_ERR_INVALID_STATE. I was able to narrow it down to the initialization of the touch controller. The wakeup pin is configured as input, PU, irq on fallind edge. Without this, the ESP32-S3 will go into light sleep. ...
