I just mount the new APM 2.5 with version v1.7.3, everything works very well and flies very well. BUT with my old GPS receives only 1 or 2 sat, after 20 minutes of waiting. If I put it back on v1.4, after 3 to 4 mins at the most, it is fixed. When I back on v2.5, after half hour he receives only 2 sats?? ... I am connected to the old plug GPS and it has the blue LED flashing!
Is there a particular configuration to v2.5 with MediaTek MT3329 10Hz GPS Adapter Basic ???
Many thanks by advance for your help
