Emlid Reach M+ Power Issue

Hello to everyone

I am working on mapping with Emlid reach m+ and DJI Phantom 4. I trigger my Emlid device via the LED on the Phantom 4’s arm. However, on this flight, the device suddenly shut down while operating normally and only the orange power light remained on. I don’t understand what the problem is? Here is the log file of the device

Did it go orange in the middle of a session of normal operations or did it only boot to orange and not go beyond that? I have had most of our M+ and M2 receivers at some point hang on orange and in some occasions it was not getting enough acceptable satellite signals and on other occasions I think it was a power glitch. I have learned that I cannot rely on them booting correctly when indoors even if I am at a south facing window and sometimes I need to connect it to a fast-charge phone charger in order to “jump-start” it. I don’t know if this really does anything and obviously my previous method of powering works for a time, but if I can get it to boot correctly off of a good phone charger the normal power method usually starts working again.

Thank you for your answer.

I have made 5 flights with the Phantom 4. There was no problem in the first 2 flights, but in other flights, when I turned off the embankment and turned it back on, all the lights turned on properly, but within 1-2 minutes it turned orange again. I am using a powerbank with a 5v output to power the Emlid

When I look at solid flight data, I see a lot of interruptions, is this normal?

I see 8 good GPS and 3 good GLONASS with a 4-minute stoppage in the middle. Was this a battery swap?

Yes, there was a battery change in 4 minutes.

Thought so… and on the small gaps in the stream of the “good” satellites that is normal. If you PPK I would try with and without GLONASS to see the difference in fix you get.

As for the power issue I am sure someone from Emlid will come by and take a look at your report. I really don’t see any interruptions in the stream that would be a result of a power interruption.

There was one more thing on my mind. I do the triggering event with the led lights on. Since the forward overlap is 80%, it triggers too often. Is frequent triggering like this a problem for emlid reach m?

Hi İzgi,

Welcome to our community!

As Michael noticed, the logs recorded by the receiver stop in case of power interruptions. However, as I can see, the log is continuous, and the time marks were collected during the whole flight except for the battery change period. I’ll discuss your case with the team and get back to you soon.
