[RAK5010 - BG96] GNSS doesn't work with LTE-M1 network

Conditions:

I have enabled gpsOneXTRA to enhance the performance of GNSS.
Power saving mode is disabled.
The board is outdoor and there is no cloud.

Tests:

1-) GSM Network registred (EDGE)
The position is fixed after about 1min.

2-) LTE network registered (CAT-M1)
I never have a fix.

Could you tell me if you can have a fix with LTE network?
Do you have any idea what can cause this?

Thanks

Hi,

The gnss and network moudle are not mutually influenced, so maybe gpsOneXTRA assistance data needs to be updated regularly. You can update the bin.

Hi,
My assistance data is up to date and I tested differents files (several path for xtra2.bin and xtra3grc.bin).
Also, I get a position when I am registered with GSM networks but not with LTE networks.

Thanks

Hi,

Actually 5010 just transmits the AT to bg96, and there is no CAT M1 in our test environment. So maybe you can consult quectel directly on their forum. Query whether the network effect gnss or not.

Hi nero,

I posted the same message on the their forum :

Also, could you tell me, how long do you have to wait after power up for a position fix in your test environment?
And what url do you use for it? (I use http://xtrapath8.izatcloud.net/xtra3grc.bin)

Hi,

We also test in GSM environment, it costs near 30s.
And use xtra3grc.bin too.

Hi nero,

Thanks for the information.
I will keep you informed of the quectel answer.
