Unable to Upload Sketch or Send AT Commands to ESP8266

isaacrlevin · July 29, 2024, 3:02pm

I bought a ESP8266 ESP-12 ESP-12F NodeMcu D1 Module on Amazon and am having a hard time connecting to it with Arduino IDE.
Amazon.com: ESP8266 ESP-12 ESP-12F NodeMcu D1 Module WeMos Lua 4M Bytes WLAN WiFi Internet Development Board Base on ESP8266 ESP-12F, Compatible with WeMos Wifi Module : Electronics

I am able to send AT commands with PuTTY but am not able to upload sketches or even send AT commands in Arduino IDE.

I have made sure the baude rate and port is the same on both but all I get in Arduino are ERROR messages

What could I be doing wrong? Here at my Tools in Arduino IDE

Load the blink sketch from Files/Samples and show all the output.

Just retry a few times; if that doesn't work, shut down the IDE and try a few more times; if that doesn't work, do a COLD reboot, etc. BTW, change preferences to show verbose output.

Not sure what a cold reboot it but I unplugged and replugged the module. Here is the verbose output

My reply is getting hidden, but I am getting the same error after cycling the module. What info in the logs do you need to see?

That's it

Sorry if this is obvious, but are you holding down the Flash/Boot/Pgm button, NOT Reset. When you see Connecting press and hold that button (usually on the right) untill you see progress.

Even dumber question, where is it on the board I have? Do I have to hook it up a breadboard and connect a pin?

sonofcy · July 29, 2024, 5:59pm

Looks like it. Here is what you need to know.
Must be LOW to enter Flashing mode, that means a switch with one side on G and the other on D3/GPIO0/Flash

bummer, this module didn't come with a breadboard and I don't have one handy
