- BLE (ESP32): fast advertising (20-30 ms) for 30 s, then 152.5 ms, as the nRF52 interface; the library default kept 30-60 ms forever - Live map tiles: the WiFi drops after a minute with nothing missing - ES8311 to standby while the I2S clocks are off, set up again before the amp comes on - Buzzer: no channel (DMA out of memory) waits out the samples instead of spinning above the UI loop - OTA: the image header check waits for its 16 bytes - Comments: P10 is just the LED; the LCD SPI clock is 40 MHz on the wire Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
