    This is from Bluetooth Specification: "a friendly host name can be up to 248 bytes in length, hence the response packet will be in excess of this value"

    sorry for not enumerating this fact earlier

    --edit, FYI the fucntion cuts of the 248th byte if it exists, replacing it with a null character

    this is a modified if statement:

    Code:
    if(q == 248 && resp[q+9] != 0x00){
    host_fname[y][q-1] = resp[q+9];
    host_fname[y][q] = 0x00;
    break;
    }

    In that case give the magic number a name so that it is easily seen to be the maximum length of a friendly host name.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
