RE: Can anyone help me to clarify the concept of the isochronous channel?

Hi,

The term "physical channel" is not an RF channel but rather a set of rules known by two devices to be in a connection - that includes phy, channel map, hopping sequence, connection interval, access address. Each new set of these rules makes up a new physical channel, and what is meant in the overview - an isochronous channel doesn't use an established LE connection channel but creates a new one.

Hello,

There is an external content creator that is quite good, NovelBits. I don't know if you have seen this one, but you may find it useful:

The short answer is that BLE audio is in the making, but currently it is not ready from Bluetooth. Only half of the Audio specification is decided, so currently audio over BLE is not possible.

I am not sure specifically what parts of the BLE Audio specification that is done and not, so how this would be done with the isochronous channels I am not sure. Perhaps it will be certain channels used, but since it has to be compliant with the older BLE spec, I assume they will not take certain channels and use it only for this.

Best regards,

Edvin
