and I didn't see any references to analog multiplexers so I have no idea how your code relates to your circuit.
If you could enlighten me that would be great.
Can you please post a link or some documentation that correlates the circuit you are using with the library you are using or quote something your previous posts that explains the connection between the 4052 and Altsoftserial. ?
I don't see any connection between the two. If I missed something please tell me what it was .
