Hi, I’d a small question about the new AWS OTA library. Specifically, in the OTA-Agent Orchestrator, I can’t see any MQTT subscription calls. In the simple OTA Orchestrator, a MQTT subscription is done just after the call to mqttDownloader_init. I assume there should still be calls to subscribe to the jobs and stream topics… Am I missing something there ? 1 post - 1 participant Read full topic ..read more

When I update OTA, met error [iot_thread] Error: No OTA data buffers available. Why do the error happen, how do fix it? And [ERROR] Firmware signature verification may have failed. Which happen, because error above. I think so. Is it true? 2 posts - 2 participants Read full topic ..read more

We are using self-signed certificates for code signing our OTA devices. This certificate has expired and we want to update all our devices with the new certificates. This certificate is hardcoded in the OTA devices which is not allowing us to update it in any other way. Your help in this matter will be highly appreciated. 1 post - 1 participant Read full topic ..read more

I am working up to IOT on AWS and trying to implement things in stages on my target processor. I am simply trying to establish TLS MQTT communication with test.mosquitto.org. I am running the MQTT_Basic_TLS demo in Microsoft Visual Studio and it appears that the Ethernet/TCP and TLS interfaces are connecting but then I get errors when it tries to establish MQTT communication. (see below) I am not sure what I can change to make things work. Any guidance would be much appreciated. 13 6726 [IP-Task] TCP: active 29527 => 91.121.93.94:8883 set ESTAB (scaling 1) Socket 29527 → 91.121.93.94:8883 S ..read more

Hi, I am looking for subscribing to a topic example without TLS(like plaintext), In the SDK I see a sample(plaintext) where it subscribes and publishes to the same topic to get the subscription working, Can anyone please get me an example which does subscribe to a topic and waits till it receives a published message from the broker? 2 posts - 2 participants Read full topic ..read more

Hi, I have been trying to set up the FreeRTOS AWS reference integration over the past few days.

I don’t understand if the AWS CloudWatch Agent running locally includes a spooler to save metrics and logs in case of temporary connection loss. I was unable to locate it anywhere in the documentation, and I am unable to do a meaningful test to determine whether it is effective in the first person.
