Fatal error when using NB-IoT and initialization GNSS

[nathanb]

Hi,

I am working on a project where I perform location determination with GNSS and send data over NB-IoT. I have written working code where I am reading location by GNSS and I have working code where I am sending data over NB-IoT to an AWS cloud service.

Both the projects work perfectly separately but once I merge these projects I get a Fatal error.

<err> lte_lc: Could not send AT command, error: 65536
[00:00:02,122,283] <err> lte_lc: Could not set system mode, error: -14
[00:00:02,122,314] <err> lte_connectivity: lte_lc_init, error: -14
[00:00:02,122,344] <err> aws_iot_sample: conn_mgr_all_if_up, error: -14
*** Booting nRF Connect SDK v2.5.0 ***e: Fatal error! Rebooting the device.

When I use the function lte_lc_func_mode_set(LTE_LC_FUNC_MODE_ACTIVATE_GNSS) in my initialization my controller goes rebooting. I get an error message that the AT command cannot be set and that I get errors with following functions.

Could there be a problem if I use the function lte_lc_func_mode_set(LTE_LC_FUNC_MODE_ACTIVATE_GNSS) and then the function conn_mgr_all_if_up(true).

The project I am mixing GNSS with is Nordic's AWS_IoT sample.

Thanks in advance for the effort
yours sincerely
Nathan

Hello Nathan, 

Can you please provide more information about your setup? What version of the SDK are you using? Can your provide the project for meg to test?

Kind regards,
Øyvind

Thanks for looking at it but I solved the problem through lesson 2 with the course of GNSS.

Excellent!! Happy to hear our lesson was helpful!
