Error compiling for board Adafruit Feather HUZZAH ESP8266.

Other Hardware 3rd Party Boards

I am having a problem uploading code to a Feather Huzzah Esp8266. This code has been uploaded in the past with no issues. I think the issue is with the Adafruit Si7021 code sonce its the last thing to compile before it crashes with the error. I have pasted the error below.

Thanks,
P.

Arduino: 1.8.13 (Windows 10), Board: "Adafruit Feather HUZZAH ESP8266, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

OK Still having an issue. I have uploaded the errors as a file. I tried the generic board as well as the Adafruit Feather HUZZAH ESP8266 board. Same results.

OK, the error is caused by you using the WiFi library. This library was written for the long retired Arduino WiFi Shield, which uses completely different technology from your ESP8266-based Feather Huzzah board.

There is a library specifically written for the ESP8266 named ESP8266WiFi. So you'll need to modify your sketch to use that library instead of the WiFi library.

If you want help with that, you'll need to post your sketch, as well as telling us where we can find all the libraries the sketch uses.
