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
