Esp32 huzzah fritzing9/24/2023 start serial communications with Huzzah (ESP8266) start serial communication with computer Serial communications with Huzzah (ESP8266) I added serial print statements to help debug, and again it appears I'm not getting something back from the Huzzah. If so, then Software Serial needs to be used for the Huzzah as well. hopefully, powering the huzzah (ESP8266) with the USB does not render the TX/RX pins unavailable. Huzzah is power sourced from micro-USB plugged into wall outlet. Pin 3 (denoted as Tx via Software Serial) 2x resistors to get ~3.3V Rx (huzzah) Pin 2 (denoted as Rx via Software Serial) Tx (huzzah) I get no response back from the feather Huzzah when running my code and circuit. To get help on this portion, I am breaking down the problem to just figuring out the arduinohuzzah serial communication. Meanwhile, there is an LCD display that gives updates. Therefore, a message has to be sent, and a message has to be received back. Then, I want the feather to send back a message equivalent to "successfully sent to storage". The feather Huzzah sends that data over wifi to Adafruit io. Then, those 6x data points should be sent from the Arduino Uno to the feather Huzzah (ESP8266) using serial communication (Software Serial). I have a project whereby 6x MAX6675 collect temperature data that's "bused" back to the Arduino Uno.
