Hi,
I need to interface a nokia 3310, with a at89c52 microcontroller, with which I will dial the phone, thorugh FBUS,
now I downloaded gnokii, and according to their documentation the frame for making a call is:
0x01: Call Information
s Make call { 0x0001, "number", type, block }
where type:
0x01 - data call
0x05 - voice call
block:
data call (non digital lines):
0x02,0x01,0x05,0x81,0x01,0x00,0x00,0x01,0x02,0x0a,
0x07,0xa2,0x88,0x81,0x21,0x15,0x63,0xa8,0x00,0x00
data call (digital lines):
0x02,0x01,0x05,0x81,0x01,0x00,0x00,0x01,0x02,0x0a,
0x07,0xa1,0x88,0x89,0x21,0x15,0x63,0xa0,0x00,0x06,
0x88,0x90,0x21,0x48,0x40,0xbb
voice call:
0x01, 0x01, 0x05, 0x81/0x00, sendnum, 0x00, 0x00, 0x01
where:
sendnum (own number sending):
0x01: preset (depends on network)
0x03: on
0x02: off
now I know that "number" will also be sent in Hexdecimal format, however
will all these bytes to send at a specific baud rate, or they can be sent at any rate,
and how does the frame start with?
0x0001 ?
What is the difference b/w a datacall and a voice call, and how am I supposed to know if the datacall wil be over digital lines and non digital lines?
