MQTT vs HTTPS for IoT telemetry uploads

[Hank94_Red]

I’m working on a project with a few friends where we’re collecting sensor data from off grid weather stations. Each device logs to an SD card and pushes 1-5 MB batches when back on LTE. We used FTP before but I’m debating switching to MQTT or HTTPS for better reliability and scalability. Is anyone using MQTT for larger payloads and able to share how it holds up in real world conditions?

MQTT is capable of managing larger payloads, but it really shines when it comes to handling smaller, more frequent messages. If you're dealing with batches in the range of 1 to 5 MB, you might find that HTTPS offers more stability—especially over LTE, thanks to its retries and inherent security features.

This matches what I was concerned about. Have you ever had LTE timeout problems when sending multi-MB batches over HTTPS or does it usually work without issues?
