Sierra Wireless MC8790 GPS not working on RouterOS v5.4

RouterOS General
1

Hello,

I have a RB411UAHR with routeros v5.4, with the gps package installed. I have installed an minipci-e Sierra wireless MC8790, the 3G connection is working fine, but i can’t get the GPS coordinates from the terminal.
I have enabled the GPS with the command

/system gps set enabled=yes port=usb2

and running the

/system gps print

it outputs the following:

[admin@MikroTik] > /system gps print
          enabled: yes
          port: usb2
          channel: 2
          set-system-time: no
[admin@MikroTik] >

But the

/system gps monitor

output null values.

The command at!gpsloc? returns:

at!gpsloc?
Not Available

OK
2

Same with my card, did you get the Problem fixed?
