Development of a multi locker system for parcel delivery, managed by one controller with Bluetooth and WiFi connectivity. Each independent locker is secured by its own lock. All locks are wired to the main controller (up to 16 locks). The controller is connectable thru the mobile application, which selects the correspondent unit and sends the appropriate keys to open. The controller is also connected to the Internet via WiFi to report the transactions and receive remote commands.
Development highlights:
Hardware selection, searching in the market for an appropriate controller with open source code. The controller selected is based on the ESP-32 module.
Embedded software development to achieve all needed communications and functionality, including remote firmware update.
Support for the App development team, providing the classes needed to perform the Bluetooth communication and encryption of the data.
