DJ,

Are you referring to having a SCO connection while the controller is in a scatternet scenario? Or having 2 SCO connections in a scatternet (2 different piconets)?

Best regards,
Vihang

Hi Vihang,

the CC2564C is located in a mobile vehicle

Connection 1: mobile vehicle – helmet.
Connection 2: mobile vehicle – phone

There should be two SCO, better eSCO connections.

Vihang,

missing your reply: are 2 SCO/eSCO connections possible with CC2564C ?

DJ,

Sorry for the delay.

My understanding is that it is theoretically possible, but this type of topology will have many connection issues resulting in voice drops and glitches.

I am inquiring internally to get confirmation on this. Stay tuned.

Best regards,

Vihang

Hello DJ,

Following Vihang's answer.

Such a scenario is not recommended.

it really is dependent on the eSCO definitions however just by being in a scatternet we are losing timeslots every time we change between the different networks,

Due to the unaligned clocks of the two different networks.

Adding to that two voice connections will result in many missed voice packets and re-transmissions (once again dependent on the eSCO type).

Having said that this scenario is not recommended as the voice might be impaired due to the difficult topology.

BR,

Chen

Thanks Chen,

I check with customer, if it touches their use case and probably will come back.
