UNICAST from on IDC777

[johnk]

I’m evaluating the IDC777 and need to know if it’s possible to open a unicast connection to my creative zen headphones.
My setup:
1)IDC777 analog input audio
2)IDC777 is paired with the create zen headphones (00023CAA342F)
3)OPEN 00023CAA342F UTXM
PENDING
OPEN_OK 14 BLE 00023CAA342F
PAIR_OK_LE 00023CAA342F
OPEN_OK 18 UTXM 00023CAA342F
4)MUSIC 18 PLAY
OK
5)STATUS
STATE CONNECTABLE[ON] DISCOVERABLE[IDLE] ADVERTISING[OFF] SCAN_UNI[ON]
LINK 14 CONNECTED BLE 00023CAA342F MTU 250
LINK 18 CONNECTED UTXM 00023CAA342F STREAMING LC3 MEDIA 0

Observed that the sample rate is 0 and obviously the audio is not coming through to the headphones.
What am I missing or is this not possible?

Hi,
Some Zen headphones have old firmware that does not work wit Unicast. They have been unstable generally. Please try and upgrade your headphones firmware using the Creative App and that usually would make it work.
