XGPS150 5hz recording at only 1hz


I have a Dual XGPS150 bluetooth gps receiver. The Receiver out of the box is 1hz but they have a firmware update for it to make it 5hz which is what i did. The firmware update was successful, when i record with RaceChrono it says that is recording at only 1hz. Is it possible for it to be recording at 5hz but only displaying 1hz on the screen? Other than that the receiver works great with the app.

  • When i use RaceChorno2AVI, the g-meter updates only once every second :(
  • It might be you need to do some configuration on the GPS to get it running 5 Hz. RaceChrono just receives the data from GPS on what ever Hz it sending.
  • Hiuys,
    The Dual XGPS150 receiver needs a special string transmitted to it to enable the 5Hz updates. It's been said that Dual won't share the API with Android devs, but it will with IOS devs. Maybe you know of one that can advise you. Otherwise the XGPS150 defaults to the 1Hz update rate. The Dual XGPS160, for example, has a default rate of 10 Hz, so if you are interested in purchasing a new GPS receiver and have a LOT of spare bux, the DUAL 160 is for you.
  • That's correct. I have API now as I have iOS version now, and there's an update rate setting available. I will do this upcoming future versions.
