Hello Quectel Support Team,

I have a Waveshare LC29H(DA) GPS/RTK HAT connected to a Raspberry Pi 4B.

Current firmware version:
$PQTMVERNO,LC29HDANR11A03S_RSA,2024/03/19,13:55:31*20

Issue:
The module receives RTCM3 corrections from ASG-EUPOS (Polish CORS network,
mountpoint RTN4G_VRS_RTCM32) and achieves RTK Float (quality=5) within
30 seconds, but never converges to RTK Fixed (quality=4).

Test conditions:

  • Open sky, dual-frequency antenna (L1/L5)
  • 33-35 satellites tracked, HDOP 0.57-0.65
  • Distance to nearest CORS station: ~13 km (Katowice)
  • RTCM messages received: 1005, 1075, 1085, 1095, 1125 (MSM5)
  • RTK Float stable for 10+ minutes without Fixed
  • Occasional 1-2 second Fixed, immediately drops back to Float

Based on information from Swift Navigation documentation and community
forums, firmware NR11A04S or newer is required for stable RTK Fixed
convergence on LC29H-DA.

Could you please send me the latest firmware file for LC29H-DA?

Module: LC29H-DA
Current firmware: LC29HDANR11A03S_RSA (2024/03/19)
Requested firmware: LC29HDANR11A04S or newer
