error: stray '\302' in program

[schroepfer]

Hello, compiling your code gave the following errors. Pleas can you help me? BR Juergen

How have you downloaded the code? Ideally get the zip version, it looks to me that these are copy/paste errors. Usually if you retype the errant lines it fixes the problem. Sometimes selecting the text and then pasting it into say word or an email body as text only removes these unseen escape characters.

I downloadet your zip. I folloed exactly your readme. I also retyped this lines...

I just download the latest 4.2" version and it compiles correctly. What your getting is hidden characters. See here for an example: https://arduino.stackexchange.com/questions/30581/stray-302-in-program-error-when-compiling

1. Download the zip.

2. Uncompress

3. Copy the files to your IDE location.

4. Open the Sketch with the IDE

usually it will be the " symbol that need to be deleted and replaced with a simple quote. e.g. const char * host = api.wunderground.com;

Then: const char * host = "api.wunderground.com";

The credentials.h in your ZIP doesn't work! I copy the raw-text from the source on github and it works now!

[G6EJD]

I have copied a new version into the repository.

this isn't working do you know why?

You aren’t referring g to my code, but your error is due to The use of copy and paste code from usually a web page. You have ASCII codes copied that add spaces, etc to your code. Go through each identified line and remove any extra spaces at the beginning and end of any identified line. Then, (Arduino IDE) go to TOOLS, Auto Format.
