Hello
I would like to communicate Audio between two devices or more for as bigger range as possible while sending a txt to be displayed other data. So there will be also a control chip. Now
Which to choose ?
SA58646
CS6422
The 1st sends data Via FM , has an amp & gain control for mic and earphone. It also has a transciever which uses FM to transmit and recieve
The latter , has an amp & gain control for mic and speaker. Plus it has ADC and DAC and dual Delta sigma codec. And am willing to use a CC1101 as transciever.
the first does the transcieving by FM but doesn't has codec
The second has codec and transcieving can be done by 2-FSK, 4-FSK, GFSK, MSK , OOK
My confusion is : Is speech compression important so i can TRx it via FSK or just transfer the audio analog via FM?
I hope i was clear enough , your suggestions are welcome.
Kind regards
