Simple, reliable BLE thermometer app for DIY sensors

Bluetooth LE Thermometer by Dawid Fouche is a lightweight iPhone utility that connects to DIY BLE temperature modules (e.g., AT-09), provides real‑time temperature and graph views, serial data visibility, Fahrenheit support and basic theming, with simple developer support via a ticket system.

The Bluetooth LE Thermometer App establishes a connection with a Bluetooth Low Energy thermometer hardware device. In practice, it provides real-time temperature updates and offers two primary views: a thermometer view and a graph view.

Operational mechanism: For the app to function, the device must transmit temperature readings over a serial channel via a BLE module such as an AT-09, using a "\r\n" termination string.
Hardware context: The AT-09 is a common choice for DIY projects, enabling hobbyists to prototype devices and test them with applications like this one. A custom device can be built using an Arduino or similar microcontroller paired with an AT-09 or equivalent BLE module.
Compatibility and support: An existing device can be used if its internal hardware and data string align with the app’s expectations. If a device does not work, provide its model and relevant details; we will either extend support or mark it as unsupported.
