AWS IOT SDK Embedded C Shadow_Sample example code, and presumably the other two examples, are out of date with the AWS github code. The result is that you can/will get an error:
WARN: shadow_delta_callback L#506 Old Delta Message received - Ignoring rx: ????? local: ?????
when you update the AWS Shadow Device via the AWS Command Line and that update is then forwarded to the CC3220 device. E.g.
aws iot-data update-thing-shadow --thing-name mything --payload "{\"state\":{\"desired\":{\"windowOpen\":true}}}" out.txt
The fix is to get the latest code from the AWS github repository and copy it into the TI code, but you have to add the following into aws_iot_shadow.c
/* * TODO AWS team forgot to initialize the newly added parameter * 'mqttPacketTimeout_ms', so do it here. Due to this, this file is now * out of sync with the AWS v2.1.1 code base: */ mqttInitParams.mqttPacketTimeout_ms = 5000;
in the correct spot of course. So, this is FYI to anyone else using the code and also a recommendation to the TI team to get the latest from code AWS github.
