Transmit GPS data to website

[tracking]

Hello 

I would like to transmit gps data to my website in addition to nrf cloud, there is a example or documentation about this that I can take of reference? I am working with nRF 9160 DK 

thanks in advance.

Kind Regards

Julio

Yes.  The first thing I did was to test both GPS and UDP examples.

Only then did I try to put them together to make a minimal tracker using UDP and without the need for all the other good stuff in your asset_tracker app.

So I now wait for udp Idle.

However, from the code in the gps sample I then get an error from

```

at_cmd_write(at_commands[i])

```

AT_XSYSTEMMODE,  (fails on this one)
AT_MAGPIO,
AT_COEX0,
AT_ACTIVATE_GPS

so GPS is not activated.

XSYSTEMMODE is probably redundant but why would it throw an error?

Hi,

Its highly likely because the modem is already enabled (AT+CFUN=1) at this point. Please check that "modem_configure()" isn't called, and that "CONFIG_LTE_AUTO_INIT_AND_CONNECT=n" is set in your project.

 

Kind regards,

modem_configure() *was* being called; CONFIG_LTE_AUTO_INIT_AND_CONNECT=n is set.

So I removed modem_configure().  The result was that we never get the LTE_LC_EVT_RRC_UPDATE (idle) event so it just hangs.

Is something else needed instead of modem_configure()? (per the udp example)

Presumably the lack of modem_configure would also prevent sending of data via udp?

Hi Paul,

 

My strongest apologies! This comment from me is written a bit too fast (ie: its wrong..)

You should check that modem_configure hasn't been called yet, before setting system permissions, like XSYSTEMMODE.

So, issue your AT-commands, then call modem_configure() to connect to the LTE network.

 

Kind regards,

I tried that.  It gets to modem_configure() - same code as in UDP sample - and we then fail with:

```

Could not send AT command error -8

```

This is happening inside lte_lc_init_and_connect_async() for which AFAIK we do not have the source.

Regards.
