Configure AWS IoT Core with ESP8266 WifiBee

[AyeZian]

The tutorial to connect the AWS with the ESP8266 can be found here. You'll need to create an AWS account, as well as download the Arduino IDE and prepare it to download code to the ESP8266. The tutorial uses a different model of the ESP8266, however, the process to connect the two should still be similar.

Making the AWS account was pretty straight forward. First year is free to make an account, there's only a $1 fee so that AWS can verify the card being used is valid. The $1 charge does not go through, so it should go away after 3-5 business days. There were a few things I thought the group should decide on. Mainly if we were going to create a certificate, what permissions we were going to allow, and how we would manage the account.

As for the setup of the WifiBee-ESP8266, there are some libraries that need to be installed which are found here. After running however, there are some compiling errors that popped up that pertained to the code from one of the packages that needed to be installed. This is something I still need to look into.

These are the errors that pop up for me.
