I Built an App to control this tiny Robot

Watch Carl's Video: https://youtu.be/teeNgLN_ZRI TinyFast File Shrinker Tool: https://tinyfast.app In this video I share everything I learned building an Android and iOS native app to control an ESP32 robot over Bluetooth Low Energy (BLE), from choosing BLE vs Wi-Fi and designing a scalable architecture, to solving Bluetooth issues, optimizing animations, and implementing over-the-air (OTA) firmware updates. If you're interested in native app development, ESP32, Arduino, BLE, or robotics, I hope you find it useful! ⏱ Timeline 0:00 - Intro 0:33 - Carl's Robot 1:23 - Bluetooth vs WIFI 2:38 - Bluetooth Low Energy 101 3:28 - Code Architecture 4:23 - Bluetooth Layers 4:51 - Buffer Problem 5:36 - Robot Animation 6:53 - My Mac OS App to shrink images 7:07 - Bootloader 8:18 - App Design and Reveal
