The JieLi (JL) Bluetooth Test Box is a must-have for hardware teams! It supports:
🔸 Parallel testing of 2 devices (4+ recommended for efficiency)
🔸 Configurable tests via dip-switch (music playback, call frequency deviation)
🔸 Clear displays for device name, status (🎵/📞), and real-time frequency data
🔸 Physical buttons for playback control (pause, skip, volume)

Ideal for production line validation!

Normal Test Procedure Description for JieLi (JL) Bluetooth Test Box

1. Enable various test functions based on actual requirements, configure the dip switch settings, and determine whether to test call frequency deviation.

The KT148A chip supports easy on-board programming via UART—perfect for prototyping!

🔧 Key steps:
1. Ground Pin 5 at power-up to enter download mode.
2. Connect USB-to-TTL (CH340G) with crossed RX/TX.
3. Flash using PC software.

Works with 3.3V–5V and minimal peripherals. Prefer pre-programming? A dedicated download board is also available.
