RS2 LoRa range issue

[millsy.g (Grant Mills)]

I am absolutely having the same issues.
I only have RS2’s, so I can’t really test it with anything else.
But I can’t get anything over 100m with LORA this season. I have tried purchasing two new antennas, and there has been no change.
If I swap to pairing the base with my phone, I can use it with nTrip and it works perfectly.

I don’t know when exactly it started, but March seems about right.

Actually, now that I think back, I have been suffering this issue for quite a bit longer than that. I was having issues almost a year before I just was in an urban area so I chalked it up to all the buildings that were around.

I first reported the matter on this forum in January
If I remember, the problem had surfaced earlier but was not as noticeable. I mostly work on small sites so it would not be immediately noticeable.

Hi Grant,

As LoRa issues can be caused by different reasons, we would like to investigate each of the requests individually. Can you send the Full System report, raw data from the base and rover, and photos of your environment to support@emlid.com? I’ll look at them.

I just sent in the logs and some photos of the setup.
Very flat land, lost radio around 250m

Hi Grant,

I got your logs! Let me take a look at them, and I’ll let you know once I have any updates.

Grant,

I see some cycle slips and gaps in the data you’ve shared.

I have some suggestions I’d like you to check:

• Try to tune the radio by changing the radio frequency in the available range.
• Let’s also try a lower the air data rate. You can test the setup with 9.11 kb/s and then with a 4.56 kb/s air data rate (set the same rate on both the base and the rover).
• Ensure that the LoRa antennas are firmly attached.

Can you also try to switch the base and the rover (configure the base as a rover and the rover as a base)? Do you see the same behavior this way?
