Is it possible to transfer .xml files with max size of 50kb from IOT device to AWS cloud using MQTT ?

It is possible to transfer XML files up to 50KB in size from an IoT device to AWS using MQTT. Remember the following though:

• MQTT has a maximum payload size limit of 128KB per message. So files up to 50KB can easily be transferred in a single message.
• On the device, publish the XML file contents to the appropriate MQTT topic for uploading files.
• On AWS, set up an MQTT subscriber that can receive messages on that topic and save the file data to S3 or another storage service.
• If the file is larger than the maximm payload size, it will need to be split into multiple messages. The subscriber would then need to reassemble the file fragments.
• Make sure the IoT device has permission to publish to the required MQTT topic. And the subscriber role allows pulling files from S3.
