Gl-mt3000 v4.1.2 beta : quectel eg25-g with external USB enclosure

[bOcy]

Background: my mudi finally didn’t survive the last drop and encounter heating and reboot issues, so I took out the quectel eg25-g modem and installed it into a USB enclosure from taobao/Lazada

Connected to the gl-mt3000, it can detect the modem and the network but is unsuccessful with auto setup or manual setup

I then tried connecting the modem to the gl-ax1800 and gl-axt1800 (both current stable firmware v4.1) and the modem is able to auto setup and provide internet

For your information.

Footnote: my other USB modem the Huawei e3372h-320 works fine on the gl-mt3000 (and gl-ax1800, gl-axt1800) as tethering
I can use 3 telco sim cards on the eg-25g while only 2 works on the e3372h-320
footnote2: mango firmware 3.2 can use e3372h-320 but not the eg25-g with enclosure

Hi,MT3000 supports the following 4 quectel modules.
1.EM060K-GL
2.EM120K-GL
3.EM160R-GL
4.RM520N-GL
Other quectel modules may not work.

Oops then I guess my eg25-g won’t work on my brume 2 when it arrives

[bOcy]

wow rm520n-gl yummy, gonna go look for it with external case

[alzhao]

Old Quectel modems, e.g. EC20, EC25, EP06, EG25-G should work just fine.

[bOcy]

On the brume 2 or beryl ax ? Didn’t work on my beryl ax test unit as mentioned in my original post

Will try again later

[Dipin]

Both of them should be able to work. Our engineers have found the root cause of EG-25G not working. Please wait for the method we provide later to verify whether it can work normally.

[bOcy]

Do you use any enclosure for rm520n-gl ?

Only found this design so far

I didn’t use any enclosure.

You can use this command （gl_modem -B 1-1 AT AT+QGMR）to check the firmware version of the modem

[lincoln]

This module does not support raw IP mode. You can try to modify it, and then re-plug your module and dial it up.

[bOcy]

still stuck at connecting

[lincoln]

Maybe you can update the firmware of the modem

[lincoln]

Attachment size limit, please wait

[lincoln]

Can you give me your email, I will send it to your email

[bOcy]

I sent by pm, thanks.

[bOcy]

Thanks lincoln for patiently assisting

updated eg25-g firmware and can now auto setup data connection on beryl ax

Further thing to report

The USB modem doesn’t stay connected to mt3000 after around half - 1 hour, internet also become very unresponsive or totally stopped, screenshot show that modem totally gone from the modem page

I also checked by connecting the modem to axt1800, can stay connected whole night till morning
