Will the CYW207xx, in any of it's variants (06, 07, 19), provide the peer-to-peer or master-to-slave, auto pairing, performance we need? We'll settle for half duplex, but we don't want to rely on companion smart phones. Two (or more) units must be totally stand-alone (self pairing) to perform the TT task.
Yes, the function is supported. We need to implement the functions in application firmware.
Like if both master and slave had no input ability. We can set the fixed pass key in master side. After connection, slave side send the pass key to master to complete the pairing.
