Hi, I've been developing a phone app to control a piece of software I have running on a Raspberry Pi and want to be able to interact with the program via the phone.
I have setup the NodeMCU with the Arduino IDE to recieve the packets but I've realised the board is unable to simulate keypresses through USB.
I have a Teensy LC board lying around and I'm wondering if I could use the RX and TX pins on the NodeMCU to direct the received packet strings through serial to the Teensy so I can then simulate the keystrokes?
This has been my first time doing anything properly with hardware like this so any help on how I could go about doing this would be greatly appreciated. Eg: is it possible, what pins should I connect?
Thanks.
