BC127 SPP commands to control android volume


Is there a way in which the BC127 can control volume on an android phone using SPP or HID? if so what are the commands for it?

kind regards,

Hi @Bharatb,

According to your description, does controlling the volume mean increasing or decreasing the volume on the phone?
The command for volume control, which allows you to increase or decrease the volume, can be found in Table 5-2: A2DP Commands.
For more details, please refer to page 132 of the BC127 Melody Audio 7.x User Guide at the following link:


Hi Jerdung,

Yeah i was trying to get away from using the A2DP connections and only HID, and yes it was increasing and decreasing the volume
