Hello guys,
I have nRF9160DK board here with me and the nRF Connect SDK v1.3.0 environment installed. I want to connect to AWS IoT Thing through the MQTT connection.
I used cloud_client example and your documentation from here as a starting point. My AWS IoT device is properly created on the AWS account and certificates are downloaded into nRF0160DK. In addition to that, here is how I modified my prj.conf and Kconfig files of the cloud_client example.
prj.conf:
# # Copyright (c) 2020 Nordic Semiconductor ASA # # SPDX-License-Identifier: LicenseRef-BSD-5-Clause-Nordic # # General config CONFIG_NEWLIB_LIBC=y CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y CONFIG_RESET_ON_FATAL_ERROR=n CONFIG_NCS_SAMPLES_DEFAULTS=y # Log level # For more verbose and detailed log output, set the log level to # CONFIG_CLOUD_CLIENT_LOG_LEVEL_DBG=y instead.

endmenu
module = CLOUD_CLIENT
module-str = Cloud client
source "${ZEPHYR_BASE}/subsys/logging/Kconfig.template.log_config"
menu "Zephyr Kernel"
source "Kconfig.zephyr"
endmenu
However, when I try to connect to the cloud I get the following error messages:
E: mqtt_connect, error: -116 E: Failed to connect to cloud, error: -10
Is there anything I am missing here?
An interesting thing is that a few months ago, with ncs v1.1.0 or v1.2.0 I was able to connect to the AWS IoT Cloud by using the same approach (see this thread).
Thanks in advance for your time and efforts.
Sincerely,
Bojan.
