Provisioning Certificates Kills GNSS in the asset tracker v2

[Marshall]

Hi There. 

I'm using the Asset Trackerv2 as a base for my application. 

If I provision certificates at boot pior to enabling the LTE connection. the GNSS is never enabled.

I've definitely tracked it to provisioning certificates - after hours of work. 

The function call is standard 

#if defined(CONFIG_MQTT_LIB_TLS)
static int certificates_provision(void){
    int err = 0;

    LOG_INF("Provisioning certificates");

#if defined(CONFIG_NRF_MODEM_LIB) && defined(CONFIG_MODEM_KEY_MGMT)

    //err = modem_key_mgmt_write(CONFIG_MQTT_TLS_SEC_TAG,
    err = modem_key_mgmt_write(24,
                   MODEM_KEY_MGMT_CRED_TYPE_CA_CHAIN,
                   ca_certificate,
                   strlen(ca_certificate));
    if (err) {
        LOG_ERR("Failed to provision CA certificate: %d", err);
        return err;
    }
#endif  
    return err;
}
#endif /* defined(CONFIG_MQTT_LIB_TLS) */

Any ideas? 

Thanks

Hello Marshall,

I will get back to you on this.

Hello Marshall,

Could you provide me the .conf file your are using? And could you run CEREG for me?

Regards,

Elfving

[Marshall]

Hi Elfving - here is the complete prj.conf

at+cereg? = +CEREG: 0,1,"A680","00054B02",7

at+cereg=? = +CEREG: (0,1,2)

I also have the aws.conf and the debug.conf as fragments in the build (these are unchanged)

Could you run XMONITOR for me?
