Aroma Shooter® firmware 2.2.1 update

2026.10.03 ·Aromajoin

Firmware 2.2.1 adds a new HTTP API: after a shoot command, the device now reports back that it received the command and started diffusing.

Aroma Shooter® firmware 2.2.1 update

A firmware update (version 2.2.1) for Aroma Shooter® is now available.

What’s new

  • Diffusion confirmation — when you send a shoot command, the device replies received once it has accepted the command and started diffusing. No reply means the command was not accepted.
  • New generation-neutral HTTP API (/asn/*, firmware 2.2.0 and later) — shoot scents, get the device identity and the firmware version. Every response includes the device serial, so you always know which unit replied when controlling several.
  • Browser-friendly — every endpoint answers CORS preflight, so web apps can call the device directly.
  • Clearer LED indicators — green ×3 when Wi-Fi connects, a short red ×2 when the connection is lost.
  • Fully compatible — the existing /as2/* endpoints keep working as before.

For endpoints, request formats and samples, see the Aroma Shooter HTTP API documentation on GitHub.

How to update Please follow the firmware update manual below.

This manual was prepared in 2024 and refers to the app by its former name, “Aroma Shooter” (now AromaCreator®). The steps are the same, so we are sharing it as is. An updated version will be uploaded at a later date.
