Troubleshooting OTA Update System for ESP32 in Home Automation
@Daniel kalu Updating
over-the-air (OTA) is a bit challenging, especially with error handling for smaller applications. If you’re facing connection timeouts or failed uploads with PlatformIO or Arduino, it might be due to network issues or the ESP32 struggling with large firmware files. Reduce firmware size by disabling unnecessary features could help. But for better control and reliability, consider using ESP-IDF’s OTA framework, which offers features like error handling and rollback. You could also set up a dedicated OTA server (using Mongoose or Nginx) to serve firmware updates, handle device requests, and manage version control and device registration. Implementing error handling and integrity checks on the ESP32 is necessary to ensure smooth updates.4 replies
