It is recognized and I see this msgs:
[MAV 001:1] GPS 1: detected as u-blox at 230400 baud
[MAV 001:1] EKF3 waiting for GPS config data
[MAV 001:1] u-blox 1 HW: 00190000 SW: EXT CORE 4.03 (6c5018)
But the configuration is not saved even with GPS_SAVE_CFG=1 and I have the following repeated msgs:
PreArm: GPS 1 failing configuration checks
GPS 1: u-blox solution rate configuration 0x10008
I cannot takeoff in LOITER but I was able to take off in ALTHOLD and then switch in LOITER with success.
The number of seen GPS was 16, that I think is low for this kind of GPS but it could be related to unsuccessful configuration.
