Could you try for example other samples that use GPS? Does the same thing happen?

Can you always receive signal after two minutes and then it slows down irregularly, or is the issue showing up right from the first fix?

Best regards,

Michal

yes now I could find the issue. Actually I flashed the lessons 6 exercise 1 solution code there they had set CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL =y so it seeks for signal from external antenna.
but in my case I don't have external antenna so we tried with internal antenna so I disabled it CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL =n now I could receive signal for every 2 mins.

but now what is the issue means I'm getting the data irregularly, like sometime I get first fix signal at 3rd minute sometimes at 8th minute, or 10th and some time it only searching more than half hour. I kept the board near to a window only. What is the issue could you help me.

What happens when you just flash Asset Tracker? Can it detect the GPS signal as well?

But in 1st exercise of nRF cloud we can receive the location details but why can't get in this GNSS exercise code. What could be the reason?

You could put a GPS antenna outside and have a wire going to it, that is the solution we have at our office.

Otherwise you won't be able to hop over the fact, that GPS is satellite-based.

yes, I'm working inside a building so we can't get latitude, altitude information's if we are inside a building right.is there any other way to achieve the output?.

Hello,

To get the GPS data you need to acquire the signal from several satellites.

Are you perhaps inside a building? For testing GPS you should preferably be outside, or maybe put the device next to an open window at least.
