求助：mp2530开发板pppd拨号问题

free314

谢谢你关注！！！！

1  首先交叉编译pppd源码包，生成拨号所需的程序pppd和chat
2 配置三个拨号脚本ppp-on,ppp-on-dialer,ppp-off
ppp-on

#!/bin/sh
#
# Script to initiate a ppp connection. This is the first part of the
# pair of scripts. This is not a secure pair of scripts as the codes
# are visible with the 'ps' command.  However, it is simple.
#
# These are the parameters. Change as needed.
TELEPHONE=*99***1#      # The telephone number for the connection
ACCOUNT=                # The account name for logon (as in 'George Burns')
PASSWORD=               # The password for this account (and 'Gracie Allen')
LOCAL_IP=0.0.0.0        # Local IP address if known. Dynamic = 0.0.0.0
REMOTE_IP=0.0.0.0       # Remote IP address if desired. Normally 0.0.0.0
NETMASK=255.255.255.0   # The proper netmask if needed
#
# Export them so that they will be available at 'ppp-on-dialer' time.
export TELEPHONE ACCOUNT PASSWORD
#
# This is the location of the script which dials the phone and logs
# in.  Please use the absolute file name as the $PATH variable is not
# used on the connect option.  (To do so on a 'root' account would be
# a security hole so don't ask.)
#
DIALER_SCRIPT=/pppdial/ppp-on-dialer
#
# Initiate the connection
#
# I put most of the common options on this command. Please, don't
# forget the 'lock' option or some programs such as mgetty will not
# work. The asyncmap and escape will permit the PPP link to work with
# a telnet or rlogin connection. You are welcome to make any changes
# as desired. Don't use the 'defaultroute' option if you currently
# have a default route to an ethernet gateway.
#
exec /pppdial/pppd debug lock modem crtscts /dev/rfcomm0 115200 \
        asyncmap 20A0000 escape FF kdebug 7 $LOCAL_IP:$REMOTE_IP \
        noipdefault netmask $NETMASK defaultroute connect $DIALER_SCRIPT

ppp-on-dialer

#!/bin/sh
#
# This is part 2 of the ppp-on script. It will perform the connection
# protocol for the desired connection.
#
exec chat -v                                            \
        TIMEOUT         5                               \
        ABORT           '\nBUSY\r'                      \
        ABORT           '\nNO ANSWER\r'                 \
        ABORT           '\nRINGING\r\n\r\nRINGING\r'    \
        ''              \rAT                            \
        'OK-+++\c-OK'   ATH0                            \
        TIMEOUT         30                              \
        OK              AT+IPR=115200                   \
        OK               AT+CGDCONT=1,'IP','CMNET'      \
        OK              ATDT$TELEPHONE                  \
        CONNECT         ''

ppp-off
略去
运行pppd-on

问题就在这里，正常情况下要rcvd一个addr,不知道问题出在哪里了，望哪个高人不吝提点

这个问题已经困扰我很长时间了，很郁闷啊，小弟在这里恳求大家了
PS：我是通过蓝牙设备利用蓝牙手机网络拨号上网的
