WRL-24408 SparkFun Thing Plus - ESP32-S3 NO Serial Output

Hello All,

I’ve been programming SparkFun ESP32 products for years and I’m having problems getting Serial to work on this product.

I created a basic Serial test with the following code…

void setup() {

Serial.begin(9600);
while(!Serial);

Serial.println(“SETUP Complete”);
}

void loop() {

delay(1000);
Serial.println(“Loop”);
}

I am using the board definition in the Arduino IDE (v2.3.4 on Win11) of “SparkFun ESP32-S3 Thing Plus” and it is located on COM6. I have tried several other board definitions but nothing seems to work.

I can compile and upload this sketch but there is no output on the IDE Serial Monitor.

I have a SparkX ESP32 Thing Plus C and the sketch works just fine.

I have closed the IDE and restarted. I have restarted my computer. I have cycled power on the board.

I checked Win11 Device Manager to see if there any “Hidden” devices assigned to COM6 and there are none. One thing I did notice is that COM6 of the device is "USB Serial Device (COM6) and the
SparkX ESP32 Thing Plus C is USB-Serial CH340.

Thoughts??

John

Does this work for you?
