AVR-Chat

Hi all,

I am trying to get some info from an old 6120i nokia phone. According to
some readings FBUS.
I sent 120 times (uint8_t)0x55.  Then I also sent 0xd1 command  in a frame
wich starts with 0x1e etc. however i did not get anything. I was supposed
to get ACK and then my info. The phone just resets and nothing happens.
The usart0 on the atmega162 is ok. The ATmega162 supply voltage is around 3
V.
Did anyone face this problem before? Am I missing something?

Javier

The guys in this chat dont comment this questions, but I like broke 
the rules, :)

First, the F-Bus is bi-directional serial type bus running at 
115,200bps, 8 data bits , it´s correct in your app?

Second, you must send 128 0x55 not 120, you must use google to find 
better info.

If you have not already go to The Linux Gnokii Project and download 
the source code. This group has excellent documentation on the 
commands used with different Nokia phones. 

Thirth, I sugest that, you do a C, Pascal or Delhi program and try to 
comunicate with de cell, when your program its ok, you can put them 
inside microcontroller.
