Summary

• add a new mobile_remote.html page for phone-based robot control
• support both Bluetooth serial (Web Serial) and Wi-Fi (ws://<ip>:81) connections in the browser
• redesign Drive Control to joystick-only (remove duplicate direction buttons)
• add two concentric joystick rings and apply gait tiers:
  • inner ring (forward/left/right): walk gaits (kwkF/kwkL/kwkR)
  • outer ring forward: trot gait (ktrF)
  • outer ring left/right: in-place rotation (kvtL / kvtR)
  • backward remains unchanged (kbkF)
  • joystick release now sends kup (stand) instead of d
• fix joystick reset centering by switching knob to center-anchor positioning with offset variables, so release returns to true concentric center
• replace separate “Raw Command” and “Token Encode” blocks with one unified command sender:
  • selectable payload mode: ASCII text or binary numeric bytes
  • supports token-optional direct send, and token-aware encoding following Web Coding Blocks rules (encodeCommand)
  • ASCII payload can be converted to byte values for uppercase-token binary framing
  • in binary mode, alphabetic payload characters are converted to ASCII byte values automatically (e.g. a -> 97, abc -> 97 98 99)
• update index.html to include a new entry link to the controller page with zh/en/ja labels
• rename index entry text from Petoi Remote Controller to Petoi Web Controller (Under construction) and sync translated labels
• stack the two portal entry buttons vertically so they always appear on separate lines
• add Web Bluetooth (BLE) fallback when Web Serial is unavailable on mobile browsers
• support BLE characteristic discovery (Nordic UART / HM-10 style + writable/notify fallback scanning)
• add BLE send path into transport priority (serial -> ble -> wifi) and BLE notify log output
• improve Wi-Fi connect UX on iOS/mobile: default IP value, explicit empty-IP prompt, visible connecting/failure feedback, HTTPS mixed-content hint, and saved last IP restore
• show immediate Wi-Fi status line updates on connect attempt/failure and trigger explicit iOS HTTPS warning alert for private IPv4 targets
• remove the quick action Clap button from the mobile remote control panel
• when HTTPS blocks insecure ws:// connection (mixed content / insecure WebSocket), show a local-version download dialog with direct link to releases
• add GA4 tracking snippet to mobile_remote.html with the same tracking ID (G-6XRBBDPBJS) used by other pages
• rename controller page title/heading to Petoi Web Controller and remove phone/mobile wording in page copy
• update index zh description text by removing the 打开 Blockly 工作区， prefix as requested
• add Petoi cat-head logo favicon links to mobile_remote.html tab icon (assets/logo.svg)
• standardize favicon declarations in index.html, main.html, and help.html using the same 3-link set (icon/shortcut icon/apple-touch-icon)
• add adaptive mobile layout rules for main.html:
  • auto-detect mobile-like touch viewport and switch layout by screen tier (compact/small/regular)
  • auto-apply portrait vs landscape layout classes for Blockly area and side panels
  • optimize mobile spacing, button sizing, and scroll behavior for console/serial panes
  • keep toolbox and workspace usable on small screens with tuned min-height/width proportions
  • hide top draggable splitters in mobile mode and keep desktop behavior unchanged
  • add orientation guidance hint (recommend landscape in portrait)
• convert primary action buttons to icon-only in mobile mode with long-press tooltip labels:
  • run/stop/save/load/upload/show-code/generate-log/clear/quick-connect buttons now have icon metadata
  • long press (touch hold) shows translated action text tooltip without affecting click behavior
  • language switch and quick-connect state changes now re-apply icon/text mapping safely

Testing

• parsed inline script syntax for mobile_remote.html with Node (new Function(...))
• parsed inline script syntax for index.html with Node (new Function(...))
• re-validated script syntax after BLE fallback and Wi-Fi UX updates
• re-validated script syntax after local-version download dialog additions
• re-validated script syntax after joystick redesign and unified command sender changes
• re-validated script syntax after joystick recentering and outer-ring rotate mapping changes
• re-validated script syntax after changing joystick release command to kup
• re-validated script syntax after binary alphabet-to-ASCII payload parsing changes
• re-validated script syntax after GA4 snippet insertion
• re-validated script syntax after controller naming and copy updates
• re-validated script syntax after index entry rename to Web Controller
• re-validated script syntax after favicon link insertion
• parsed inline script syntax for index.html, main.html, help.html, and mobile_remote.html after favicon standardization
• parsed inline script syntax for updated main.html after adaptive mobile layout changes
• verified adaptive CSS block exists in styles.css
• manually reviewed diffs for language switch and route wiring

Notes

• command transport priority in remote page: Bluetooth serial first, then BLE, then Wi-Fi when Bluetooth is not connected
• if browser supports neither Web Serial nor Web Bluetooth, UI now shows a clearer fallback message to use Wi-Fi
• mobile layout adaptation is rule-based and reversible on resize/orientation changes; desktop behavior remains default
