Hi, thanks for your response. I tried what you said but still when I sent UART 1 it’s still froze and when I open the port for USB-TTL it doesn’t receive anything.
Do I need to plug both USB at the same time? Or I will sent first UART 1 and open tera term for USB-TTL?
Is there any chance that you can help me step by step about the connections of the module and the USB-TTL converter?
If it still not working, is there other way to enable uart?
Thank you!
