EG25-G GPS issue

[Bepulse]

I`m currently using the EG25-G.
Our module was working well however out of a sudden it stopped getting GPS data.

I found that other people had similar issues, like in this forum:

GPS does not work on EG25-G

Hi, I have a device: https://www.aaeon.com/en/p/10-inches-rugged-tablet-computers-rtc-1010 The device has a built-in LTE EG25-G module (installed drivers: Quectel_LTE&5G_Windows_USB_Driver_V2.1). Unfortunately, I do not know what antenna is mounted inside, because I cannot find such information on the manufacturer’s website. I have the same problem as above.. GPS location doesn’t work when I use LTE connection. When I unscrewed the housing from the LTE module, it turns out that the antenna …

However solution is not clear.

From the logs, I have good signal strength and satellites are visible.

Follows some logs from the device:

Module is active.

Response: +CME ERROR: 516

This error code usually indicates that the GPS hardware connection is abnormal or the circuit design is not reasonable, I recommend you to check it carefully

[Bepulse]

ok @herbert.pan-Q . However from the logs, I have good signal strength and satellites are visible. So it doesn’t seem to be hardware-related.
Is there any firmware update that should be done? I read in another forum someone from Quectel sending a new firmware version to another person.

[herbert.pan-Q]

I have sent the latest firmware to you,pls check and try

[Bepulse]

ok thanks. I flashed the new firmware version (EG25GGBR07A08M2G_30.204.30.204). During this initial ~1 hour of test, it seems way more stable and I`m not getting the errors anymore from the GPS location.

Hello, can you please provide me the firmware EG25GGBR07A08M2G_30.204.30.204? Is it the latest version? I downgraded to 30.007.30.007 and now my EG25-G MINIPCIE device is not working

Hello, can you please also provide me with the latest firmware? I also have been trouble trying to get the gps to work on my end too. Thanks.

[herbert.pan-Q]

Please provide your current firmware version

Hi, same issue here with EG25GGBR07A08M2G_30.203.30.203.
I’m in clear sky, fresh xtra2 data. EG25 indicates 9 visible satellites but no fix after hours.

Can you please provide me the 204 firmware to test if there is some improvment with it ?

Thanks

Hello,

I am facing the same issue right now with EG25GGBR07A08M2G_A0.204.A0.204.
I’d like to test using the 30.204.30.204 that is being tested in this post.
Can you please provide me that firmware?

Thank you.

FYI, I spent a few days testing after updating the firmware on my module back in Dec24, but the issue persisted. It seems the firmware update didn’t resolve the problem, so I eventually gave up and opted for a different module instead.
