I am working on a desktop WiFi to RVR setup using an ESP32 from Sparkfun. The network connection from the desktop to the USB port on the ESP board is working okay. I can send RVR requests via the ESP to a desktop serial terminal (CuteCom). The values in hex are the expected values.
I can also send via PuTTy messages over the WiFi and see them in the serial terminal. So bi-directional traffic is working.
When I connect the ESP to the RVR USB port it powers on and accepts the network connection and commands. But the RVR is not responding.
Does the RVR USB allow communications? It would seem so given directions for MicroBit usage.
Is there a special setup for USB serial communications? I’m using the 115200 used by the serial port.
