Description

The SDK for the ESP32 microcontroller written in C++ for Arduino. This SDK allows ESP32 Arduino devices to communicate with their atServers with edge encryption.

I had the opportunity to implement various low-level cryptographic functions that the atProtocol required such as :

• RSA 2048 encrypt/decrypt
• AES 256 CTR encrypt/decrypt
• RSA 2048 sign
• RSA 2048 key importing

and Atclient implementations such as:

• AtClient put
• AtClient get
• AtClient delete
• AtClient pkam authentication

UMass Boston Winter 2022

This SDK was primarily written so that UMass Boston students could use it in their final CS project. Their final project involved creating a simple actuator/sesnor ESP32 demo using the atPlatform.

They needed an app (written in Flutter or Java) that could send commands or read data from an ESP32 (running at_esp32).

I played a strong role in the development of this SDK and the success of the students who used it. I also had to hold things like workshops and office hours to help students understand how to use the SDK. A video playlist tutorial was also created, which can be viewed here.
