GSP is not working

RE: GSP is not working

Heidi — Tue, 26 Nov 2019 12:06:26 GMT

The gps_sample I sent you was just the GPS sample in ncs (ncs/nrf/samples/nrf9160/gps) on tag v.1.1.0 with an added line to check that the modem firmware running was the most recent one.

So you can to build the GPS sample on tag v1.1.0 and it should work.

If you check out this git repo there is a udp_gps example that combines UDP with GPS.

Best regards,

Heidi

Hi Heidi,

The switch position was in the 'CON' position when I tested previous gps firmware. With this new version of gps_sample.hex, the GPS is finally working. Thank you for your efforts to make it work. What changes do I have to make from the gps sample included in the SDK release? Can you send me a copy of source code through my email? But it still requires to run in the open-sky outside building.

Do you have a working example that combines UDP or TCP/IP with GPS? If not, can you help me to create one, which will be very helpful to us. We have been taking too much time to make GPS work.

Thank you for your help,

David Zhou

I wrote 2 instead of 12 in my original reply, sorry about that. Just to be completely clear, this switch in the image below should be to the left. Use something small to move it.

Try with this .hex file instead and let me know how it goes.

I tried the Switch to con position (left). It still doesn't work.

Thank you,

[quote user="TigerD"]The SW2 (switch 2 - name exactly) is switched to the left. ( It is the default position of the board out of box).[/quote]

I think my instructions were unclear. Switch it to the opposite of the default position out of box. Towards CON and not ANT.

Hi Heidi,

I updated modem firmware to version 1.1.0.

The SW2 (switch 2 - name exactly) is switched to the left. ( It is the default position of the board out of box).

I tested outside under open sky on the parking lot. No GPS data received.

Just as a reminder, I am at New York. The satellite above Norway may be not the same satellite above us. The udp_gps sample, the mask has _GNSS_, and gps sample has _CONFIG_. I don't know about details. I am not sure that has anything to do.

Thank you,

David

Hi!

Can you update the modem firmware to version 1.1.0 that was just released - if you haven't already done that. You can download it here.

Also, make sure SW12 located right above the nRF9160 SiP on the board is switched to the left.

Then go outside under open-sky and wait a few minutes and you should get a fix.

Let me know how it goes.

Best regards,

Heidi

Hi Heidi,

I have loaded the hex file into the board (revision 0.9.0) with external antenna attached to GPS. I tried both in-building and on the outside parking lot. GPS position is not received.

Attached is the message:

Okay, I see. Just to cover all bases, can you use the Programmer application in nRF Connect to flash the attached hex file to your device and see if that changes anything?

Hi Heidi,

I am using MASTER branch of the samples located at: ..\root\ncs\nrf\samples\nrf9160\gps

The LTE LINK MONITOR worked and displayed text messages, but afer I clicked open logfile, it doesn't work anymore. So I had to use terminal programs to capture the display messages:

RE: GSP is not working

Hi!

Which branch of NCS are you working on?

Where are you testing these samples? You should preferably be outside.

The sample located in samples/nrf9160/gps on the master branch of NCS should work out-of-the-box, under the correct conditions.

Can you open LTE Link Monitor when running the sample and provide me with the log file by pressing the button shown in this image

Best regards,

Heidi
