Hi!
I trying to connect to mobile phone NOKIA. My phone is 7210. I successfully connected to phone via FBUS, but cannot connect via MBUS (but I need it!)
When I send FBUS commands, I correctly receiving ACK. But when I trying send any commands via MBUS - no answers from phone (for exammple, no answers for 0x1F,0x00,0x10,0x15,0x00,0x06,0x00,0x06,0x00,0x02,0x00,0x00,0x01,0x19 - is it correct string for MBUS?)

I remember, that Nokia NMT-450 sends packet "to 0xff from 0x00", when power it turned on or off. On 7210 I see the same packet on FBUS (0x1E, 0xff, 0x00, ...), but there is no any data on MBUS line (I viewing this line either UART or oscilloscope). Is it rigth? Must be any packets on power on and off on MBUS?

Maybe I need turn any signals to any level? What I doing wrong? How can I use MBUS on Nokia 7210?

Hi,

The following nokia models do not support Mbus communication
protocol:

- 7210
- 6610
- 6100

and who knows what future models.

Best Regards
