OTA is for updating an already working device from the BambuHelper web UI.
Full is for first-time flashing, recovery, or ESP Web Flasher use.
First-time flashing? Easiest path is the hosted web flasher at keralots.github.io/BambuHelper - pick your board in the dropdown, click Install, and the browser handles bootloader + partitions + firmware in one go (no downloads, no flash offsets). The
-Full.binfiles below are only needed if you prefer the generic ESP Web Flasher or are flashing one of the community / beta boards that the hosted flasher doesn't list yet.
Updating from v3.7.4? OTA the matching
-ota.binfor your board. Settings are preserved.
Changes
Fixes
- Setup hotspot not appearing on ESP32-C3 Super Mini boards - many C3 Super Mini units have an antenna hardware defect that makes WiFi unusable at full transmit power: the
BambuHelper-Setuphotspot never shows up and the board cannot join your network. WiFi transmit power is now capped at 8.5 dBm on the C3 builds (esp32c3,esp32c3_round). If your C3 board was stuck during first-time setup, this release fixes it. (#146)
Improvements
- Waveshare Touch-LCD boards now use their full 16 MB flash and 8 MB PSRAM (
ws_lcd_200,ws_lcd_154,ws_lcd_280) - a new partition table with much larger OTA slots, and PSRAM enabled, which unlocks the 4-printer beta on these boards.- Updating over OTA is safe and keeps your settings - PSRAM support activates right after the update.
- Flashing the
-Full.binerases saved settings on these three boards (the new partition layout rewrites the settings area) - use Export settings in the web UI first and import the file back afterwards. OTA updates are not affected.
- Web UI - per-plug power settings are greyed out while power monitoring is disabled, making it clearer which options are actually in effect.
- Build system - the Improv WiFi provisioning library is now bundled with the source tree; the upstream registry package pulls in a wrong
WiFidependency that breaks fresh builds from source.
