xbee bluetooth + sc16a

Hi everyone,

As I understood SC16A Rx pin is TTL.
Can I direct connect it to Xbee bluetooth Tx pin? Since it only 3.3v.

Thanks
Leom

Better use the Bluebee with SKXBee-Board so that you can connect them directly to SC16A.

Hi all,

I tried to use 5v ttl buffer logic to convert the 3.3v signal to 5v ttl now.
Works well now. :D

But there is another problem encounter, which is the data framing will out for split second some time.
But the sc16a able to catch the start bit back on track.
For this kind of comm without RTS, CTS, is there any other idea can solve this issue?
