Hello,
At the moment I am trying to send an sms with my nokia 6210 via fbus and a microcontroller. The microcontroller I use is the Atmel atmega8. The RX Pin of the Phone is directly connected to the TX Pin of my microcontroller(only a resistor is between them, to get the right current for the phone).
TX and GRD Pin of the Phone are also directly connected(without resistors). Now I'd like to say the phone via FBUS that he have to send an sms. I think the frames I use for that are right, because when I send them to the phone, I get an acknowledge frame from the phone and after a while the "sent message frame". When I recieve this frame the microcontroller sends back an acknowledge frame to say the phone "I've got your sent message frame".
But here is my big problem:
The phone does NOTHING! It doesn't send any message, it only freezes and reboots after a while. Thats all it does! I don't know what the problem is.
Can you say me what the phone wants me to do or what I'm doing false?
I hope you can help me,
greetings spamonymous
P.S: If you think my english is bad, sorry for that,my mother tongue is german.
