Probleme Atmega64 cu Bluetooth LMX9838

Am un Atmega64 pe o placa de dezvoltare si vreau sa-l leg cu un modul bluetooth LMX9838 care sa comunice cu un telefon. Am facut si un convertor care sa ma ajute cu debug-ul.

 

Daca conectez placa la computer si rulez programul, pe hyperterminal primesc stringul corect.

Daca conectez modulul BT la computer si trimit stringul cu Realterm, modulul se conecteaza corect la telefon. Acest lucru nu a mers cu alte hyperterminale, nu stiu de ce, si nu pricep cu ce e Realterm mai special.

La sfarsit daca conectez placa la modulul BT, nu se intampla nimic.

 

Am incercat sa pun CTS de la modulul BT la masa sau sa-l scurtcircuitez cu RTS, ca sa mearga fara handshaking, dar nu se schimba situatia.

 

Ma poate ajuta cineva? Multumesc anticipat.
