Hello Team,
I am currently experiencing difficulties connecting my nRF7002DK to AWS IoT Core using the aws_iot sample in nRF connect SDK v2.9.0 , which I have adapted with a few modifications. Below are the changes I made and the steps I have taken so far:
Changes Made to the Application Configuration:
1. Wi-Fi Configuration (Kconfig):
CONFIG_WIFI_CREDENTIALS_STATIC=y CONFIG_WIFI_CREDENTIALS_STATIC_SSID="my_ssid" CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD="my_pass"
2. AWS IoT Credentials:
CONFIG_AWS_IOT_CLIENT_ID_STATIC="my-thing" CONFIG_AWS_IOT_BROKER_HOST_NAME="xxx.amazonaws.com"
3. Certificates:
I have attempted both of the following methods to include the AWS IoT certificates and keys:
- Directly using the exact certificates and key downloaded from the AWS IoT Console.
- Manually reformatted them as described in the documentation on Nordic Dev Academy by adding quotes and newlines as below manner
"-----BEGIN CERTIFICATE-----\n" "MIIDQTCCAimgAwIBAgITBmyfz5m/jAo54vB4ikPmljZbyjANBgkqhkiG9w0BAQsF\n" "ADA5MQswCQYDVQQGEwJVUzEPMA0GA1UEChMGQW1hem9uMRkwFwYDVQQDExBBbWF6\n" "b24gUm9vdCBDQSAxMB4XDTE1MDUyNjAwMDAwMFoXDTM4MDExNzAwMDAwMFowOTEL\n" "-----END CERTIFICATE-----\n"
Observed Issue:
Despite the above configurations, I am consistently unable to establish a connection to AWS IoT Core. I suspect there might be an issue with either the certificates or the way the credentials are being processed, although I am unsure.
Additional Information:
Device: nRF7002DK
Sample Used: aws_iot
I have attached a portion of the logs from the device console below for your reference:
