Firmware version 6.3.0 is out and running slicker than a greased pig at a county fair! Producing this update has been non-trivial, involving complex integration and feature work, building UIs in LVGL and introducing a load of Library and IDE updates. Here are all the juicy tidbits: General User Experience Improvements: * Added automatic captive portal redirection for easier setup. * Shortened access point name for configuration mode (now Piggy Config). * Enhanced the look of the configuration login page. Library Updates: * Adafruit BusIO: 1.15.0 → 1.17.0 * Adafruit GFX Library: 1.11.9 → 1.12.0 * ArduinoJson: 7.3.0 → 7.4.1 * AsyncTCP: 3.3.3 → 3.3.8 * ESPAsyncWebServer: 3.6.2 → 3.7.6 * GxEPD2: 1.5.6 → 1.6.3 * TFT_eSPI: 2.2.20 → 2.5.4 * arduino-esp32: 3.1.1 → 3.2.0 * ESP-IDF update: 5.3.2-282 → 5.4.1-1 You can install it using the Web Installer. If you’re already on version 5.x or later, your existing configuration will be preserved during the upgrade. Enjoy the update! Stay humble, hog sats!

Some new experimental piggy hardware (ESP32-S3-LCD-2-C) has just arrived but unfortunately, the camera mount has been installed backwards at the factory, making it impossible to connect the OV5640 camera ribbon. Oh Grunt! Back to rolling about in the mud while we get this sorted! ⚡️🐽 #LightningPiggy #STEMM #BitcoinKids #BuildInPublic #bitcoin

While fiat savers are wallowing in the mud, nostr:nprofile1qqsz9qvwcv7cq78xf9jt2cwg8xm5gvljxu2494l4h44tptejtfulg2gpz3mhxue69uhkummnw3ezummcw3ezuer9wcq3gamnwvaz7tmjv4kxz7fwv3sk6atn9e5k7pggsea keeps on shipping! Check out our latest v6.2.0 update, it’s a meal of new user experience improvements. For starters, the device now displays the exact day and time it last checked your wallet; updated every minute in "no_sleep" mode. Talking of “no_sleep” mode, for main course, you can now choose the vibe that suits your power source: - "no_sleep" – always awake (great for mains, solar, and big batteries) - "custom_sleep" – default 6-hour snooze (perfect for batteries, solar and custom set-ups) - "endless_sleep" – deep hibernation with shake-to-wake (perfect for small batteries!) Here’s the full change log: User Experience (UX) Improvements - Detailed startup feedback: The device now shows real-time status updates during startup (e.g. connecting to Wi-Fi, syncing time, launching webserver, fetching wallet data). - Always-on clock display: The current time is now continuously shown while the device is powered on, not just before going to sleep. - Localized weekday names: Weekday names are once again translated into your local language. - Configurable sleep modes (Feature Request #35) detailed above. - Last wallet check timestamp: The device now shows the date and time it last checked your wallet (updates every minute in no_sleep mode). Fixes & System Enhancements - Switched to standard NTP: All time synchronization now uses pool.ntp.org, removing the dependency on timeapi.io. - Automatic Wi-Fi reconnection: The device will now attempt to reconnect automatically if Wi-Fi is lost. - Periodic auto-restart: The device now performs a daily (every 23 hours) restart to proactively avoid potential issues. - Cross-platform build support: The same firmware build now runs seamlessly on both physical and virtual (QEMU) ESP32 devices—no recompilation needed. You can install it using the Web Installer, which has now hit a milestone—no known open issues! If you’re already on version 5.x or later, your existing configuration will be preserved during the upgrade. Enjoy the update! Stay humble, hog sats!
