Detailed code samples

Specific code samples that describes different ways to use samples and interact with Live Objects

Customizable parameters & commands

This release introduces a new, simpler way for using parameters and commands with Live Objects. It also offers a dead simple way of sending data to Live Objects.

MQTTS support

MQTTS support + comments in the code.
Notice: many changes in the code (both in arduino_secrets.h and .ino files), plus a new LiveObjectsCert.h file that holds the needed Root CA certificate in order to connect using MQTTS.

Adding APN settings

You can now set custom APN settings in the ARDUINO_SECRETS file.

Also, the #define preprocessing directive holding the Live Objects API key changed from

#define SECRET_MQTTPASS

to

# define SECRET_LIVEOBJECTS_API_KEY
