ESP8266 Community Forum

- Wed Aug 24, 2022 6:11 am #95144 I am working on an Arduino and esp8266 project and I am facing a problem that after uploading following code nothing is showing on serial monitor. I am using USB connector to power up the Arduino then connected Esp8266 with it by connecting all 6 wires. I bypass the Arduino by connecting reset with ground. There is no error while uploading Tosca course code but its showing nothing. Tried connecting esp8266 TX with Arduino RX and esp RX with Arduino TX. And TX with TX and RX with RX also but still hard luck. Baud rate is same 115200 port is also correct but still not working. Kindly help me to figure it out ! Thanks PS: I attached the schematic, kindly check that.

Code: Select allvoid setup() {
  Serial.begin(115200);
  while(!Serial) { delay(100); }
}

void loop() {
  Serial.println("Hello!");
  delay(1000);
}

- Fri Aug 26, 2022 6:28 am #95152 It sounds like an ESP-01 (like 99% of these questions; that's why I gave up responding).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
