Quectel EC200U-EU GNSS problem

Hi,
I am trying to use the GNSS feature on a QUECTEL EC200U-EU. Revision it’s EC200UEUAAR02A07M08.
Log:
AT+QGPS=1
OK
AT+QGPSLOC=0
+CMS ERROR: invalid length

Each time I get the same error: “invalid length”.
Also, if I’m sending AT+QGPSINFO?, all I’ve got it’s “OK” without any other GNSS information.
Is something I’m missing? This module should support GNSS, right?
Thank you,
Alex

Hi
Do you find any solution for this problem?

Unfortunately no.
So far no answer from Quectel technical team. It’s not even clear to me if this module support GNSS or not. In all the documents it’s stated that GNSS it’s “optional”.

It supports GNSS. I tested EC200U-EU several times. It works sometimes and other times I get the error “invalid length”.
