Thanks, @biggar, indeed I was incorrect with the generalization, and the Cochlear TV streamer and the N7 may use a different frequency and connection protocol than BT. So the N7 may or may not communicate directly with a third party BT transmitter.
However, the N7 is recognized by my old Samsung N3 as well as the N9 as a BT device and a receiver as such. So, if a third party audio BT transmitter can stream to a mobile, then (theoretically) the N7 may receive the (TV) signals (with the expected latency) from the mobile, bypassing the need of the Cochlear TV streamer (with whatever frequency it uses).
I’ve read, and mentioned earlier here, that the Note 9 can receive BT signals transmitted from a car stereo as well as from a guitar adapter. So (again, theoretically) it should receive the same from other BT audio transmitters. Then, an appropriate app may transfer the signal to the N7.
What’s your thought about this…? Please point out any flaw.
Cheers
