Joe,
For the tone to work you need to have an open audio channel, I have done this by streaming sme music from my hone and using one the tone examples in the manual.
A2DP_STREAM_START 10
AVRCP_PLAY 11
TONE V 64 N C6 L 4 V 128 N C6 L 4 V 255 N C6 L 4 V 128 N C6 L 4 V 64 N C6 L 4
OK //At this point I can hear the tones over the music
AVRCP_PAUSE 11
A2DP_STREAM_SUSPEND 10
What is your use case?
LED’s I am not sure at the moment.
Regards
Matt
