Hi,

I am new to bluetooth and i was going through the bluetooth spec. Few terminology used in the spec is little confusing to me.

I could not understand what exactly is a physical channel and physical link. Similary what is logical transport and logical link.

Can someone please clarify me?

Regards,
 

Physical channel is one hardware channel, and physical link so.
But logical channel is software channel. it is needed to divide one physical channel into several logical channel, such as into voice channel, data channel, SMS channel etc.
 
Thanks for the reply.
