求助：mp2530开发板pppd拨号问题
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 \

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
