Not connecting to nRFCloud

[Yano]

Hi, we have an nRF9160DK (0.8.3) and it does not connect to the nrfcloud.

We have updated to the latest firmware 1.0.0

We only have nb-iot here so we  didn't use the iBasis sim, instead using a vodafone V-Sim (which is active). 

Are we missing a step here?

Thanks

Hi Ian,

You should see this bar get green if you have a connection:

Yes, you need to manually send "AT+CFUN?" to update all the info from the modem so it can be displayed in the LTE Link Monitor.

But it does not look like you have a connection.

It may be that you need to set the MCC/MNC as well with AT+COPS command.

so:

AT+CFUN=4
#wait 10 seconds
AT%XEPCO=0
AT+CGDCONT=0,"IP","ciot.vodafone.com"
AT+CGAUTH=0,"PAP","vodafone","vodafone"
AT+COPS=1,2,"<your_specific_MCC/MNC>"

AT+CFUN=1

(Adding the AT%XEPCO=0 since some networks does not support ePCO)

---

For the asset_tracker it uses the lte_link_controller driver which sets different parameters. 

So you need to set the configurations (similar to the AT commands) in the prj.conf file. (All this is explained in the NCS tutorial)

CONFIG_LTE_NETWORK_MODE_NBIOT=y
CONFIG_LTE_PDP_CMD=y
CONFIG_LTE_PDP_CONTEXT="0,"IPv4v6","ciot.vodafone.com""
CONFIG_LTE_LEGACY_PCO_MODE=y

The AT+COPS functionality can be added as a function by you in a similar fashion like done in the lte_link_controller driver. (if it's actually needed to select the MCC/MNC)

This is something that your operator will tell you how to connect to their network.

(ref: CONFIG_LTE_PDP_CONTEXT

CONFIG_LTE_PDP_CMD etc.)

Hi Martin,

We don't seem to be having any luck even adding the AT%XEPCO=0

How can we find the MCC/MNC number?

We are doing this with the asset tracker running is that OK?

Also do we need to press "search networks" (AT+COPS?) doing this seem to timeout the modem and stop LED 3 flashing.
