No satallite data at all on Reach RS

[Arnault]

Dear all,

I’ve just set up a new Reach RS unit as a rover (after having already installed one other Reach RS unit as a base, and two Reach units as rovers).

All the units previously installed worked well. But this time the new Reach RS does not work properly (although the configuration seems OK - see report below). There is absolutely no information in the “Status” window (no satellite bars, no position information…). From time to time I have a message stating “please provide unobstructed access to the sky”.

But the new reach unit is in a similar position as the other devices receiving satellite informations. I tried also to let the new Reach RS quite a long time (20 min.) to get satellites, and also to move in a place with even less obstacles around (top of a hill in the countryside with no trees or buildings around), but still no satellite information. I have also tried with “positioning mode: single”, this does not change anything.

All the other functionalities (network, access to the unit via web browser or Android app, LED blinking…) work well.

What do you think? Is it possible that the GPS chip inside the unit is disconnected or broken?

Are there some things I should try (hard reset…) before sending back the device to the seller?

Thank you in advance for any advice. Best wishes,

Arnaud

Arnault,

Thanks for the thorough report. Something is definitely not right about this unit. Before applying for a replacement, I can suggest two things just in case:

1. Do a hard reset by holding the power button for 15 seconds.
2. Reflash the unit.

If none of the above works, then this is most likely a hardware issue and the unit can be replaced. In this case, please contact our support at support@emlid.com and include a link to this thread and order details.

Dear Egor,

Thank your for your answer. I confirm that I had tried the two things you indicate (hard reset and firmware re-installation), and it did not change anything.

I will therefore contact the reseller and/or Emlid support for the replacement of the unit.

Sincerely,

Arnaud
