In my project ,currently we use ESP32S3 WIFI with aws_sdk to connect aws cloud so now i have integrated the EC200U-CN module for connecting with cloud , is it possible to communicate with cloud with existing aws_sdk using EC200U-CN. if this possible, then guide us how to connect the cloud using aws_sdk.

Thanks for your reply. I have a question regarding the AWS SDK for Embedded C. Does this SDK play a role in my case? I have already used it with the Wi-Fi driver to connect to the cloud on an ESP32. Can I reuse it with the EC200?

Additionally, if we use the EC200 as a modem, do we definitely need AT commands as the only way to configure and communicate with AWS?

If your current device development does not use the Quecopen SDK, then you can only use the AT command to connect to AWS

Thanks for your reply…

  • Is it possible to send & receive large packet data using AT commands?
  • We are planning OTA (Over-the-Air) software updates from the cloud to the device. Can this be achieved using AT commands?

  1. Yes, but depending on the application protocol you choose, if you use MQTT, large packets will be downloaded in fragments
  2. OTA can be used, but for the modem, only transparent transmission
