Настройка SIM7000E через PPP
Пытаюсь настроить SIM7000E через ppp. SIM7000E подключается к Beaglebone Black через кабель micro USB. Beaglebone использует ядро 5.10.168-ti-r71 (Debian). Драйверы SIM7000E были успешно установлены, а также установлен ppp.
Я вошел в каталог /etc/ppp/peers, скопировал файл провайдера и назвал его gprs. Gprs-файл выглядит так:
example configuration for a dialup connection authenticated with PAP or CHAP
This is the default configuration used by pon(1) and poff(1).
See the manual page pppd(8) for information on all the options.
MUST CHANGE: replace myusername@realm with the PPP login name given to
your by your provider.
There should be a matching entry with the password in /etc/ppp/pap-secrets
and/or /etc/ppp/chap-secrets.
user "myusername@realm"
MUST CHANGE: replace ******** with the phone number of your provider.
The /etc/chatscripts/pap chat script may be modified to change the
modem initialization string.
connect "/usr/sbin/chat -v -f /etc/chatscripts/gprs"
Serial device to which the modem is connected.
/dev/ttyUSB2
Speed of the serial line.
115200
nocrtscts
debug
nodetach
ipcp-accept-local
ipcp-accept-remote
Assumes that your IP address is allocated dynamically by the ISP.
noipdefault
Try to get the name server addresses from the ISP.
usepeerdns
Use this connection as the default route.
defaultroute
Makes pppd "dial again" when the connection is lost.
persist
Do not ask the remote to authenticate.
noauth
Затем, когда я пытаюсь вызвать gprs, набрав:pppd call gprsРезультат таков:
Script /usr/sbin/chat -v -f /etc/chatscripts/gprs finished (pid 1186), status = 0x0
Serial connection established.
using channel 2
Using interface ppp0
Connect: ppp0 <--> /dev/ttyUSB2

Я не понимаю, в чем проблема. Может кто-нибудь помочь с этим?
