Re: RS-232 Modules are not working with ESP32's
You are correct. I fixed that! I think the problem is because I am not using a null cable. I just bought one and will update once it arrives. Thanks! A null modem cable was required. I thought the cable I had was that. To recap: - Esp32 TX (GPIOs remapped above) to TX of each module . - Connect eac...
