ESP8266 trobleshooting

Hello, I am using the ESP8266 to run my project, however I can only run a simple coding but cannot use it as IOT function since it always pop out of this instruction. All these library I done installing but it still keeping the warning. Can someone help me thank you so much!

WARNING: Category 'Network' in library lwIP_PPP is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_enc28j60 is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_w5500 is not valid. Setting to 'Uncategorized'
WARNING: Category 'Network' in library lwIP_w5500 is not valid. Setting to 'Uncategorized'

it is a warning. ignore it.

But I just can run the normal pin on/off function act like normal microcontroller. The wifi function that use with BLYNK cannot run... Really weird

The problem you described is completely unrelated to the warnings about the library category. These warnings don't indicate any real problem, and in fact aren't even shown when you use an IDE version from this decade.

Please ignore those warnings and focus on finding whatever might be the real cause of your problem instead.

Even though the warnings are harmless and not even shown in modern IDE versions, since they are annoying and a source of confusion for users of outdated IDE versions, I went ahead and submitted a pull request to fix the category values.

@carvellteo, your topic has been moved to a more suitable location on the forum. At the moment that you can upload code (e.g. blink), it does not belong in Installation and Troubleshooting :wink:
