In reply to mike. These are the last 3 bytes of the device's MAC address.

In testing see that when the ESP8266 connects to my hotspot, it reports a “Device Name”. For example, at the moment mine says “ESP-141DF4”. I can’t find any information on how or where this device name comes from. I have to assume it is burned into the chip just like a mac address is. I can’t find how to get that device name from within my sketch.

Anyone have an idea?

I installed windows 11 not long ago and now i’m having issues with my esp 8266 01 modules. I can upload code and run it but it will only sporadically connect to my home wifi. Some sketches will not work period. I upload the code but the sketch does not run eg your sketch to get MAC address of the 8266. I’m getting very frustrated and need some help. Has anyone else experienced these issues?

After installing Ardunino 2.2.2-rc9. Have NOT been able to compile ant ESP32 or ESP8266 boards. States “xtensa-lx106-elf-g++.exe” is missing. That file has been guaranteed by AVG because AVG claims its INFECTED with IDP.Generic.
See Arduino form. https://forum.arduino.cc/t/avg-detects-xtensa-lx106-elf-g-exe-as-threat-after-2-0-0-rc9-update/1015098
Seen on Espressif form about this same issue but NO ONE RESPONDS!
So is it INFECTED or a false positive?

ESP-01 is really very hard to get working. I tried for 2 weeks and their were no standard articles to get it working with arduino. Can you please share one and only specific article that can help me get working arduino with ESP-01 esp8266 chip?

Hi.
Both boards should work just fine. But, we usually use CP2102 (so, that’s the one we recommend).
If it comes flashed with LUA, you can use it with Arduino IDE wihout any problem.
Also, this article might help: https://makeradvisor.com/best-esp8266-wi-fi-development-board/

Excellent web info Rui !,

Hello , I’m new in IoT , just starting , and I’m trying to choose the right board , I can see for ESP8266 CH340G NodeMcu V3 Lua ESP-12E Micro USB ESP8266 CP2102 in alliexpress , but the CH340 and the CP2102 are two USB chip option , what is better , why ?,

And the Second doubt , If the ESP module has the NodeMcu Lua flashed inside , Can I use it with Arduino IDE ? , or must be reflashed ,

Thanks For the advice ,
