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: 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 is only connected to WAN port. Can the reason for the lack of GPS comm…

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.

@Bepulse

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.

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
