Better receiver diagnostics

  • UBX parsing. Validates complete bounded messages; only checksum-valid NAV-PVT produces GPS samples.
  • 25 Hz diagnosis. Reports request, Bluetooth delivery, receiver ACK/NAK and measured cadence separately. Receiver settings remain RAM only.
  • Receiver identity. Records bounded model/firmware information without delaying the rate request.
  • GPS diagnostics. Reports protocol and quality counters while retaining timing-quality requirements.
  • Acceptance. The existing Pro handshake is retained. DRG70 and Lite support remains provisional.
