01 · HOW IT WORKS

Build to reboot, in about a minute.

What shipping firmware looks like once ElegantOTA Pro is in your build.

01
Export your build
Compile as usual in Arduino IDE or PlatformIO and grab the .bin.
02
Open the device page
Every device serves its own update page - visit it from any browser on the network.
03
Drag & drop
Drop the binary on the page and watch live progress as it flashes.
04
Reboot into new firmware
The device restarts on the new build automatically. That’s the whole job.

04 · OPEN-SOURCE VS PRO

Already using open-source ElegantOTA?

The free version is AGPL-3.0 - the strictest copyleft there is. Shipping it inside a product means open-sourcing your firmware. Pro swaps in a commercial license and the polished upload experience.

05 · FIELD NOTES

Engineers ship with it.

Notes from teams running ElegantOTA Pro in production.

“All of our field devices take their updates through ElegantOTA Pro - whoever is on site opens the device’s page and drops the .bin. Not one bricked device.”
Diego M.· Firmware lead · industrial IoT
“Our techs used to open enclosures and hunt for USB ports. Now they join the device’s network, open its page and drop the new build - done in a minute.”
Priya Raghavan · Product engineer · smart metering
“The white-label page looks like part of our product, not a third-party tool. Customers update their own devices and never know the difference.”
Tom Becker · CTO · HVAC controls

Questions, answered.

Which boards does ElegantOTA Pro support?
The full ESP32 family (including S2, S3, C3 and C6), ESP8266 and ESP8285, plus RP2040 boards with WiFi - on the Arduino core via Arduino IDE or PlatformIO. It works with both the standard WebServer and async servers. ESP-IDF isn’t supported.
Can I ship it in a commercial, closed-source product?
Yes - that’s the point. Pro comes with the SOFTT Commercial License 1.3: royalty-free, closed-source friendly and valid for unlimited devices. The open-source version is AGPL-3.0, which requires open-sourcing your firmware if you ship it.
Does it update the filesystem too?
Yes. Firmware and filesystem (LittleFS / SPIFFS) images are both pushed from the same page - and Pro lets you disable either mode straight from your firmware code when it shouldn’t be available.
How do updates reach devices in the field?
The update page is served by the device itself, so anyone on the same network can open it in a browser and drop in a .bin - no cloud, no cables, no extra tooling.
What happens right after I pay?
Invites to the private ElegantOTA Pro GitHub repository and the SOFTT Discord land in your inbox the moment payment clears. Pull the library into Arduino or PlatformIO straight from the repo.
Can I get a refund if it doesn’t fit?
No - a purchase unlocks the full source code, and that access can’t be handed back, so all sales are final. Evaluate the open-source "lite" version first: it shares the same core API, so if it updates your board, Pro will too.
Buy once. Update forever.

One payment of $199. Private repository access, Discord community access, unlimited devices - and every future update included.
