Hi,
I'm trying to build a connect between the Teensy and a Nodemcu for a webhook towards a server. the connection is meant for sending only data (char or byte) when a Teensy audio mode is changed (0, 1, 2 or 3). Mode changes only take place approx 10-20 times a day, so there is a very limited data send.
I'm using Teensy HWserial pin 0 (RX) and pin 1 (TX) and on the NodeMCU I use GPIO5 (TX) and GPIO4 (RX).
The problem is that I do not get any data on the NodeMCU. I did test the Teensy (cross connected RX with TX and tested succesfully transmission between TX and RX). I checked multiple times that RX is connected with TX. Changed from char to bytes. Changed baudrates.
Does someone help me to understand this problem?
I attached the Teensy ino file and NodeMCU ino file and a overview picture.
