STM32 OTA Firmware Upgrade via WiFi: Remote Wireless Update Guide for Embedded Systems
**STM32F103 Series Chip
Seamless Wireless Upgrade Solution: WiFi Module + Custom Server Integration**
The upgrade process utilizes a BIN file format. For enhanced security, the accompanying EXE tool automatically performs CRC16 verification – checking every 128-byte segment of the original BIN file and appending the validation results.
Upon download completion, the microcontroller meticulously verifies each 130-byte data block, ensuring rock-solid reliability throughout the entire firmware upgrade process.
**Streamlined Upgrade Workflow:**
1. The user application continuously monitors for updates by commanding the network module to fetch cloud information via HTTP GET requests.
2. Critical details including firmware version and download URL are intelligently extracted from the retrieved info file.
3. When a newer version is detected, the system automatically stores the download address in flash memory, activates the update flag, and initiates a controlled reboot sequence.
4. During reboot, the BootLoader springs into action – detecting the update flag, retrieving the stored download address, and securely fetching the new firmware via HTTP.
5. The downloaded program file is then flawlessly written to flash memory, completing the upgrade cycle with precision.
**Comprehensive Package Includes:**
– Ready-to-implement BootLoader source code
– Specialized EXE tool for BIN file CRC processing
– Detailed step-by-step operation manual
