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...

Howdy, Hello I have two ESP 32 devices and I have successfully connected them to communicate over UARTs using the standard TTL interface with basic dupont jumpers. :D I have next taken the same esp32 devices and then instead I have inserted rs422 to TTL adapters and communication continues to flow p...
