k85OS v5.0.2

What's added in v5.0.2

Music Player

• Loop toggle: repeat current track (WAV and MP3)
• Delete track from file browser with confirmation
• Fixed MP3 playback speed (was decoding faster than real-time, sounded sped up)

Text Input Keyboard

• Replaced awkward double-tap-to-change-row gesture with hold-A-to-move-down (single tap still moves across columns)

Network / Router

• Fixed Home/Guest Hotspot failing to connect — root cause was a simultaneous double WiFi handshake (AP bring-up + forced STA reconnect) exhausting internal RAM needed by WiFi's own crypto; now skips the redundant reconnect when STA is already associated
• Moved several large web-page buffers to PSRAM to free up internal RAM headroom

SSH Server

• Various stability fixes to host-key generation and task stack allocation (early static allocation to avoid heap fragmentation)
• Known issue: device can still reboot when starting the SSH server — root cause not fully confirmed, prime suspects are a wolfSSL crypto buffer size setting (FP_MAX_BITS) and/or the constructor-based early memory reservation; flagged for further investigation

System Info

• Split into 2 pages (B button to switch) instead of one cramped screen

Housekeeping

• Firmware version bumped to 5.0.2 across all version strings
