i am trying to connect Nokia C903 using Bluetooth for reading messages. can it be done? fscanf returns nothing.. .

i want to read and write messages and transfer images using Bluetooth.i have connected my phones C903 and N73 one at a time with bluetooth and used the follwing code which gives an error. This is my code: b = Bluetooth('N73', 1)

   Bluetooth Object : Bluetooth-N73:1

   Communication Settings 
      RemoteName:         N73
      RemoteID:           00210863353B
      Channel:            1
      Terminator:         'LF'

   Communication State 
      Status:             closed
      RecordStatus:       off

   Read/Write State  
      TransferStatus:     idle
      BytesAvailable:     0
      ValuesReceived:     0
      ValuesSent:         0

>> fopen(b)

>> fwrite(b,[2 0 1 155])

>> btResponse=fread(b,36)

Warning: Unsuccessful read: The specified amount of data was not returned within the Timeout period. btResponse = Empty matrix: 0-by-1

i also tried fscanf but it returns nothing...

>> fopen(b)

>> fprintf(b,[3 4 5 6])

>> idn=fscanf(b)

Warning: Unsuccessful read: A timeout occurred before the Terminator was reached. idn = ''

i searched for the problem but couldn't find anything.

try

fwrite(b, uint8([2 0 1 155]))

i tried it but it says unit8 is as an undefined function for input type double.
