aws configuration asset tracker v2

[Muhammad Usman]

Hi All!

I am using nrf9160dk with ncs 2.4.0  and asset tracker v2 example . I was testing with NRF cloud it was working well as it is enabled by default.

Now the issue is that I am trying to enable the AWS in asset tracker V2

But I am getting some errors while compiling.

Can you please help me in this regard where is the issue?

I followed the following

Hi,

Which toolchain do you have as the active toolchain (I assume you are using VS Code to build?)?

Could you make sure you are using the v2.4.0 toolchain?

Best regards,

Didrik

Hi

Thanks ! yes! 

I am using ncs 2.4.0

issue resolved by adding the following lines in prj. conf files

CONFIG_AWS_IOT=y
#CONFIG_AWS_IOT_TOPIC_UPDATE_DELTA_SUBSCRIBE=y
CONFIG_AWS_IOT_TOPIC_GET_REJECTED_SUBSCRIBE=y
CONFIG_AWS_IOT_AUTO_DEVICE_SHADOW_REQUEST=y
CONFIG_AWS_IOT_MQTT_RX_TX_BUFFER_LEN=2048
CONFIG_AWS_IOT_APP_SUBSCRIPTION_LIST_COUNT=3
CONFIG_AWS_IOT_CLIENT_ID_APP=y

# Options that must be configured in order to establish a connection.
CONFIG_AWS_IOT_SEC_TAG=42
#CONFIG_AWS_IOT_BROKER_HOST_NAME=""
CONFIG_AWS_IOT_BROKER_HOST_NAME="a30695n0axlqin-ats.iot.us-east-2.amazonaws.com"

# MQTT Transport library
# Maximum specified MQTT keepalive timeout for AWS IoT is 1200 seconds.
CONFIG_MQTT_KEEPALIVE=1200

Now it compiles fine!

Is that ok?

Now question is how to update the aws certificates using LTE link monitor can you please share me the link regarding that?

Thanks & Regards,

Muhammad Usman

The LTE Link Monitor have been replaced by the Cellular Manager.

You can read how to use the Cellular Manager (the procedure is the same for the Link Monitor) here: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fref_at_commands_nrf91x1%2FREF%2Fat_commands%2Fintro_nrf91x1.html

Note that for this to work, the application must support receiving AT commands over UART. However, that should already be the case as you have CONFIG_AT_HOST_LIBRARY already enabled.
