App IntroductionBLE GroupConnect is an offline Bluetooth Low Energy debugging tool for embedded and IoT hardware engineers. No data will be uploaded to the internet; all debug content stays on your device.

Core Features:

1. Multi-device Concurrent ConnectionConnect dozens of BLE devices at the same time, control and monitor hardware in batches, perfect for mass production testing.
2. GATT DebuggingView services and characteristics in tree view, send Hex/ASCII/GBK/UTF-8 commands, listen to Notify messages, and save custom GATT templates for repeated use.
3. Automated Task ScriptsCreate timed and cyclic command scripts. Keep BLE connection alive in the background for long-running tests and OTA upgrades.
