Are you getting the below error when sening data to IoT Core using the "AWSIoTPythonSDK." ?
Here is my error :
File "/usr/local/lib/python3.6/site-packages/AWSIoTPythonSDK/MQTTLib.py", line 520, in connect
File "/usr/local/lib/python3.6/site-packages/AWSIoTPythonSDK/core/protocol/mqtt_core.py", line 199, in connect
The below can be reason for this issue
1- You have not defined policy to allow the sending message to the IoT Core topic. If that is the case create a policy for the "Thing"
You need to define
If the policies are defined than check the active version of policy, In my case old policy was active
2- Make the latest one active
Check this under your "Thing" policy settings:
Hopefully one of it works. Leave comment if it does help
