Status always 0 #134

On u-blox IDE the status looks OK (fix mode):

gnss

0 invalid 1 2D/3D 2 DGNSS 4 Fixed RTK 5 Float RTK 6 Dead Reckoning

So, on ROS topic, status have to be 1. Right?

$ rostopic echo /ublox/fix

header: 
  seq: 136
  stamp: 
    secs: 1622838693

  status: 0

position_covariance: [1.283689, 0.0, 0.0, 0.0, 1.283689, 0.0, 0.0, 0.0, 6.091024]
position_covariance_type: 2
---

And... it is always 0. My YAML:


device: /dev/ttyACM0
frame_id: gps
uart1:
  baudrate: 38400
config_on_startup: false

Any idea what could be wrong? Thanks!

As per the NavSatStatus message definition. A value of 0 is an unagmented fix. https://docs.ros.org/en/noetic/api/sensor_msgs/html/msg/NavSatStatus.html
