Hello,
I have an ESP32-CAM that I am doing some experimenting with. Programmatically, using the Arduino IDE and setting the serial port to 115200 baud. I have been able to use the Arduino Serial monitor, as well a few other simple USB/UART adapters to see the serial console output.
The issue I am having: I have connected the serial output to another MCPU's UART (STM32). But the STM32 is not receiving any data from the ESP32-CAM. Likewise, I dont have any issues using the STM32's UART with a USB/UART adapter.
Everything is running on 3.3V, so it's not a voltage level signaling issue. I've been fighting with it for some time and I can't figure out what the issue could be. I am posting here because I know less about the ESP32-CAM than the STM32 and I am hoping someone knows of a possible reason I am experiencing this issue.
Thanks!
