BLETM is a powerful yet intuitive app that enables seamless text-based communication between your iPhone and Bluetooth Low Energy (BLE) devices such as microcontrollers and IoT modules. Whether you're developing embedded systems, building prototypes, or managing smart devices, BLETM provides a wireless, cable-free way to monitor and control your hardware.
Upon launch, BLETM scans and lists nearby BLE-compatible devices. You can assign custom names to each device, making it easier to identify and manage multiple connections—ideal for workshops, labs, or field testing scenarios. Once connected, you can send text commands and receive responses in real time, allowing for smooth two-way communication with your device.
BLETM supports flexible end-of-line (EOL) settings for outgoing messages, letting you choose between LF (\n), CR (\r), CRLF (\r\n), or no line ending at all. This ensures compatibility with a wide range of devices, firmware protocols, and development environments.
You can now register frequently used commands or text strings as templates for each device. This greatly streamlines repeated input tasks, making your development and testing workflow faster and more efficient than ever. Sent messages are now displayed in a history list. Just tap on any previous entry, and it will automatically populate the send text box—making it easier than ever to reuse frequent commands and streamline your workflow.
Designed with engineers and developers in mind, BLETM is more than just a terminal—it’s a reliable companion for anyone working with BLE-enabled hardware. The app offers a free trial period, so you can explore all its capabilities with no commitment. After the trial, subscribing unlocks full access to all features, ensuring uninterrupted use in your development workflow.
