I cannot see any log through UART0. I can measure the incoming signal with oscilloscope and it does not show any abnormalities. But it is no response from ESP32. Modules are integrated in a circuit board with some peripherals (see attached image). Three boards are tested so far. The µC supply is sta...

I try to programm an ESP32-MINI-1 module via UART by using ESP-PROG. Unfortunately I cannot establish communication with the module via UART0. But I get in a programming attempt via UART1 to change the baud rate: Sketch uses 290325 bytes (22%) of program storage space. Maximum is 1310720 bytes. Glob...
