2. Device Connection & GATT Discovery

* Connect to BLE peripherals.
* Check connection status.
* Discover GATT services and characteristics.
* View UUIDs and read/write properties.
* Identify Notify and Indicate support.
* Read characteristic values.

3. Data Transmission & HEX Debugging

* Read and write characteristic values.
* Send HEX or text data.
* Subscribe to Notify and Indicate characteristics.
* Monitor incoming data in real time.
* Inspect transmitted and received data.
* Debug custom BLE protocols and Bluetooth serial modules.

4. Communication Logs

* Record sent and received data with timestamps.
* Review communication history.
* Export logs for troubleshooting and analysis.

5. Preset Commands
