Can someone here help me out with code to send data from esp32 to aws s3 storage ?

I am using esp-idf as I have other code running on the esp32 as well.

I am new to aws so any help would be good.

    Are you also using AWS IoT, which has integrations with S3, or do you just want to send data directly to S3?

    ESP32 would be collecting sensor data and this data should be sent directly to S3 Jun 14, 2018 at 6:01

Not the complete answer but a step forward: https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html

AWS has released their ESP32 support with AWS FreeRTOS.

To send directly to S3 without going through IoT Core, you will need your endpoint (obviously) and certificates on the device side to authenticate on the Cloud side. With the policies and Roles on the Cloud side, a trusted device should be able to post on S3.

  • Do you know which functions to use to send data as the test demo shows on MQTT transfer but my data is probably in KBs which MQTT can't handle Jun 15, 2018 at 3:06

    @HiteshPratyushV The MQTT spec allows for message payloads up to 256 MB; data on the order of a few kilobytes should pose no problem.
