I tried the ECHO RS485 code in Inspite of sending data from USB TTL to ESP32 I didn't receive any data on my ESP-IDF Serial monitor. To check UART interface you need to connect PC --> USB to TTL Adapter --> RX,TX pins of ESP32, build and run the uart echo and then send ...
Due to that the code runs on different devices, an extra layer is added to the code to run the WiFi part. Due to this, the code of the WiFi connection setup is different that the examples, but it should work the same. But please verify it. The thing that I don't understand is,...

Connect RX or TX on 5V for Arduino will destroy this module. You must use a logic level converter, or a 3.3V for Arduino The 3.3V supply on the for Arduino Uno has inadequate current capabilit to power this module. You must provide a separate, higher 3.3V supply(about 300mA or ...
Identify the VCC (or 3.3v input), GND, TX and RX on the ESP32-CAM Use female-to-femaleDupont jumper leadsto connect the ESP32-CAM to aFTDI UARTboard set at 3.3v. Add the code above to theESPhomenew device.Validateand compile the code into a binary file on your PC. ...
