When is the assisted GPS function in HL7800-M available?

When is the assisted GPS function in HL7800-M available?

@fyusuke,

GPS is a firmware upgrade to the current hardware available later in the year, you will need to contact your distributor to get timelines for more detailed information as it is currently confidential.

Hi,
Are you referring to Assisted GPS only or GPS in general?
I’ve started working with a HL7800 module recently and something is not very clear…

Digging through the technical specification Rev5.0 (AirPrime_HL7800_and_HL7800_M_Product_Technical_Specification_Rev5_0.pdf),
3.22 GPS Interface (page 54)

There’s a note saying that: “This interface will be available in a future release.”

Also, when running the command AT+GPSNMEA?
I get the following response:
+CME ERROR: 4
Which means “Operation not supported”

To be fair, I haven’t tried to do any sort of GPS configuration yet, but I assume that lack of configuration would generate +CME ERROR:3 (Operation not allowed) instead.

If the GPS feature is not available yet, do you have an updated release date for it?

BTW, my module is running the following firmware: BHL7800.3.4.4.3.20190531

Many thanks in advance,
Cheers

@rodrigoshaller,

So couple of things.

  • Your hardware should be good to go and it should work with the firmware you have.
  • You need to send at+cfun=0 to the unit and then you can start the GNSS.
  • Start it with at+gnssstart=0
  • The command you need to send is at+gnssnmea NOT at+gpsnmea.

at+gnssnmea=?
+GNSSNMEA: (0,1,3-8),(1000),(0),(1FF)

OK

Thanks for the clarification, Matt.
I got it working now.
