Updated at 2025-08-26

BTR17 Bluetooth V1.25 and XMOS V1.32 firmware changes are as follows:

Bluetooth V1.25

1. Added bitrate display for aptX Adaptive/Lossless codecs.

2. Modified UI display color for aptX Lossless codec.

3. Fixed the issue where charging could sometimes only reach 60% after enabling charging protection.

XMOS V1.32

1. Fixed the issue where PS5 might not be recognized in UAC 1.0 mode.

Notes:

1. When playing under aptX Lossless codec, it may take some time (normally around 30 seconds) before stably entering lossless mode. The bitrate in lossless mode will dynamically vary between 1 Mbps and 1.2 Mbps depending on the audio data.

2. The connection quality and signal interference will affect the activation of lossless mode. It is suggested to keep the phone and receiving device as close as possible, and ensure that the phone is connected to a 5GHz WiFi network (or disable WiFi).

蓝牙V1.25

1. 增加aptX Adaptive/Lossless编码下的码率显示

2. 修改aptX Lossless编码的UI显示颜色

3. 修复开启充电保护后充电有概率只能达到60%的问题

XMOS V1.32

1. 修复UAC 1.0模式连接PS5有概率不识别问题

注意事项

1.aptX Lossless编码下播放时，需要等一段时间（一般30s左右）才能稳定进入无损模式。无损模式的码率根据音频数据的不同会在1Mbps~1.2Mpbs间动态变化。

2.信号连接质量以及信号干扰会影响无损模式的开启，建议将手机和接收设备尽量靠近，并确保手机连接的WiFi为5GHz模式（或者关闭手机WiFi）。
