Expo + IoT: Device provisioning with HTTPS via WiFi
Blog post from Expo
Vincent de Lafontaine, CTO of App & Flow, shares insights on setting up a companion app for IoT devices using Expo, focusing on the provisioning flow necessary for connecting such devices to WiFi networks. Drawing from his experiences in building various IoT projects, Vincent details the process of using the react-native-wifi-reborn library to facilitate communication between a smartphone and an IoT device, highlighting the importance of sharing WiFi credentials securely. The article explains configuring the app through Expo and addresses security considerations, emphasizing that while the companion app plays a minimal role in security, the primary responsibility lies with the device maker. The provisioning process involves connecting a phone to the IoT device's WiFi, sending network credentials to the device, and ensuring the device connects to the main WiFi network. The overview concludes by demonstrating a basic provisioning flow using an ESP32 as an example, showcasing the app's capability to manage the device's connectivity effectively.
