I’m trying to send a character message from an arduino uno to an esplora by connecting their usb ports together. The esplora has a micro usb port, while the uno uses a usb B port. To hooked them up, I connected a micro usb to usb A cable to a usb A to usb B cable using a female to female usb A connector. I even hooked up the uno and esplora grounds together. But the two boards just don’t seem to communicate. Ordinarily when hooking up the esplora to my computer, the tx light flashes whenever sending the message and the message appears as expected on the serial monitor. I’ve also tested sending character messages from the computer to the uno and they seem to be read as expected. But when connecting the esplora to the uno without going through the computer, those tx lights on the esplora do not seem light up at all and the uno rx lights don’t flash either.
Any idea what could be the issue here?
