Question, why does running my program, tx ‘hello world’, change everything?
When I power up the ubw32 and the easy bluetooth module, I am able to list the
program from the computer/ubw32 side, and the list will show up on both the
transmit side, and the receiver side, which is a mac terminal window,
running the ‘screen’ program. And if I then type list from the receiver computer,
it will list again on both sides. But not before list on the tx computer.
As per the program, I dim both the tx and rx pins, but I only transmit programatically.
And I have connected tx to rx both ways, ubw32 to BT.
So anyway after I run my ‘hello world’, the KeyboarD on the receiver computer
is unresponsive, but it still will receive transmits from the ubw32, but listing
does not show up on the receiver computer again.
If there’s an easy explanation, I’d love to hear it.
What I’d like to do, is keep both sides able to type, transmit and receive. I’d like to know
what I can do to keep the receiver keyboard working. I guess there is something I
need to do after my transmit, to restore things back, but I don’t know what it is.
A reference to a useful example or some good tips would be great, thanks.
