Hello, i am trying to send data from a Teensy to a Firebeetle 2 ESP32-E, which will then send data to an app, specifically nRF connect using bluetooth. I have managed to get the serial communication between the microcontrollers, but whenever I try extracting that data using bluetooth I get...

I've switched the wires, but I'm still getting

Hello Paul, So I've moved the the TX and RX to 18 and 17, respectively. And their connected to the 0 (RX1) and 1(TX1) of the teensy. Whenever I look at my ESP32 Serial monitor, I'm getting this Here is my current set up

Hi Paul, I dug out a DEVKIT V4, specifically a ESP32-WROOM-32D. If I read the pinout correctly, there's only set of RX and TX. I've also tried connecting the the ESP32-D's RX and TX to the 8 separate sets RX and TX and I'm getting this for each one everytime I press RESET on my ESP32. So I'm...

Wait hold on, I changed the baud rate, and whenever I press the reset on my ESP32 I get this message. I'm not getting the "Message received: Hello from teensy" that you are getting.

Hi Paul, Thanks for helping me out I've tried doing your Teensy code on my 4.1 and your ESP-C3 on my ESP-E, but I'm getting this super weird error. I've searched up the specific error, but it's not really that helpful. For my set up I've connected: Teensy TX -> ESP32 RX, Teensy RX ->...

I checked the baud rate for both the Teensy and on the ESP32, and they're both on 9600.

Hello, I was following this guide between a microcontroller and an ESP 32, where its simple communication. Teensy 4.1 Code void setup() { Serial.begin(9600); } void loop() { Serial.println("Hello Boss"); delay(1500); } #define RXp2 3 #define TXp2 1 ESP32=E Code void setup() { // put...

Hello, Thanks for your reply. The reason why I have it set to 5.0 and not 3.3 is because the reference voltage I am using is the 5.0 Volt one.

Hello, I am testing the capability of a Teensy 4.1 using a photoresistor. I was googling some tutorials on how to do this an I came across this one. The only thing I changed for the most part was the code so that I could the voltage and also the luminosity of the photoresistor. int photoPin =...
