When i set network between those two modules it is OK. They found each other and set conection. But when I try to sen something by UART, it will not comunicate.
What mode do you have them in? There is currently a bug with Ad Hoc mode in the S6B firmware. We are waiting for the update.
From the release notes:
“Known Issues: … 5. AdHoc mode allows association between two modules, but does not allow transmissions.”
