    Bug in Nokia 6310i CPBR implementation?

    Hi,

    I am preparing a paper on connectivity with cellular phones and, while testing my Nokia 6310i (rev: V5.10 11-09-02MPL-1(c) NMP.) I noticed the described issue:

    ATV1
    OK
    AT+CPBS="ME"
    OK
    AT+CPBS?
    +CPBS: "ME",20,500

    OK
    AT+CPBR=1,20
    +CPBR: 1,"+351917250910",145,"Adriano Rui Gominho"
    +CPBR: 2,"934358744",129,"A.R.Gominho Optimus"
    +CPBR: 3,"931234567",129,"John Smith"
    +CPBR: 4,"123456789",129,"New Entry"
    +CPBR: 5,"123456789",129,"New Entry"
    +CPBR: 6,"937678534",129,"Oskar"
    +CPBR: 7,"956457245",129,"Brian"
    +CPBR: 8,"+44789657655",145,"Silva"
    +CPBR: 9,"123456789",129,"New Entry"
    +CPBR: 10,"+44783756655",145,"Phil"
    +CPBR: 11,"123456789",129,"New Entry"
    +CPBR: 12,"123456789",129,"New Entry"
    +CPBR: 16,"123456789",129,"New Entry"
    +CPBR: 19,"123456789",129,"New Entry"


    Note the phone is not sending the final <CR><LF>OK<CR>LF> sequence, contrary to ETSI 07.07 page 10 recomendation.
    Stranger still if I issue the following command:

    AT+CPBR=1,30
    +CPBR: 1,"+351917250910",145,"Adriano Rui Gominho"
    +CPBR: 2,"934358744",129,"A.R.Gominho Optimus"
    +CPBR: 3,"931234567",129,"John Smith"
    +CPBR: 4,"123456789",129,"New Entry"
    +CPBR: 5,"123456789",129,"New Entry"
    +CPBR: 6,"937678534",129,"Oskar"
    +CPBR: 7,"956457245",129,"Brian"
    +CPBR: 8,"+44789657655",145,"Silva"
    +CPBR: 9,"123456789",129,"New Entry"
    +CPBR: 10,"+44783756655",145,"Phil"
    +CPBR: 11,"123456789",129,"New Entry"
    +CPBR: 12,"123456789",129,"New Entry"
    +CPBR: 14,"123456789",129,"New Entry"
    +CPBR: 17,"123456789",129,"New Entry"

    OK

    This time the final <CR><LF>OK<CR><LF> sequence is received!
    Now the following command tries to read all 500 entries:

    AT+CPBR=1,500
    +CPBR: 1,"+351917250910",145,"Adriano Rui Gominho"
    +CPBR: 2,"934358744",129,"A.R.Gominho Optimus"
    +CPBR: 3,"931234567",129,"John Smith"
    +CPBR: 4,"123456789",129,"New Entry"
    +CPBR: 5,"123456789",129,"New Entry"
    +CPBR: 6,"937678534",129,"Oskar"
    +CPBR: 7,"956457245",129,"Brian"
    +CPBR: 8,"+44789657655",145,"Silva"
    +CPBR: 9,"123456789",129,"New Entry"
    +CPBR: 10,"+44783756655",145,"Phil"
    +CPBR: 11,"123456789",129,"New Entry"
    +CPBR: 12,"123456789",129,"New Entry"
    +CPBR: 15,"123456789",129,"New Entry"
    +CPBR: 18,"123456789",129,"New Entry"

    OK

    Do you see anything wrong? Only 14 entries are reported when the initial CPBR? command indicated 20 entries! Where are the missing entries? Look at the next command:

    AT+CPBR=13
    +CPBR: 13,"123456789",129,"New Entry"

    OK

    Am I missing something?

    TIA

    Adriano
