SORACOM AK-020の設定

Last updated at Posted at 2018-11-20

AK-020をRaspberry Pi, Ubuntu などで利用しようとしたら公式に掲載されているwvdialでは安定して利用することができませんでした。
最終的にpppconfigを利用するようにしたら、ある程度安定して動作していますので、そのスクリプトです。
動作確認は、UbuntuとRaspberry Piで行っています。

2021.3.16:
LINUX 5.10では正しく動作しなくなっていたので修正しました。

1. パッケージのインストール

sudo apt-get install eject pppconfig

2. PPPの設定

2-1. pppconfigによる設定

pppconfig

実行するとこのような画面が開きます。

pppconfig.png

順番に次の通り設定していきます。

項目 設定値
Provider soracom
DNS Dynamic
authorization PAP
Your ISP sora
password sora
modem speed 460800
Pulse/Tone Tone
Phone Number 99**1#
Choose Modem Config Method No
Manually Select Modem Port /dev/modem

2-2. 手動で編集

最後の３行に以下の３行を追加します。
usepeerdns
persist
replacedefaultroute

/etc/ppp/peers/soracom
# This optionfile was generated by pppconfig 2.3.18. 
# 
#
hide-password 
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/soracom"
/dev/modem
460800
defaultroute
noipdefault 
user "sora"
remotename soracom
ipparam soracom

usepeerdns
persist
replacedefaultroute

2-3. ATコマンドの編集

ATコマンドが記載されているファイルを以下のように変更します。

/etc/chatscripts/soracom
# This chatfile was generated by pppconfig 2.3.18.
# Please do not delete any of the comments.  Pppconfig needs them.
# 
# ispauth PAP
# abortstring
ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED
# modeminit
'' ATH
# ispnumber
OK AT+CFUN=1
OK ATZ
OK AT+CGDCONT=1,"IP","soracom.io"
OK-AT-OK "ATD*99***1#"
# ispconnect
CONNECT \d\c
# prelogin

# ispname
# isppassword
# postlogin

# end of pppconfig stuff

3. rules.dの登録

3-1. モデムの再登録

USBドングルを挿入したらCD-ROMとして認識されるUSBドングルをイジェクトして、USBシリアルデバイスとして再認識させます。

/etc/udev/rules.d/40-ak-020.rules
ACTION=="add", ATTRS{idVendor}=="15eb", ATTRS{idProduct}=="a403", RUN+="/usr/sbin/usb_modeswitch --std-eject --default-vendor 0x15ed --default-product 0xa403 --target-product 0x15eb --target-product 0x7d03"
ACTION=="add", ATTRS{idVendor}=="15eb", ATTRS{idProduct}=="7d0e", RUN+="/sbin/modprobe usbserial vendor=0x15eb product=0x7d0e"

3-2. モデムデバイスの変更とネットワークの起動スクリプト

/dev/ttyUSBx として認識されるUSBデバイスを/dev/modemとして認識させて、ネットワークデバイスの起動を行う部分です。

/etc/udev/rules.d/50-soracom.rules
KERNEL=="ttyUSB*", ATTRS{../idVendor}=="15eb", ATTRS{../idProduct}=="7d0e", ATTRS{bNumEndpoints}=="03", ATTRS{bInterfaceNumber}=="02", SYMLINK+="modem",ENV{SYSTEMD_WANTS}="ifup@wwan0.service"

3-3. ネットワークの起動とPPPを結びつけます

wwan0のデバイスが挿入されるとppp接続でsoracomに接続を行います。

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

allow-hotplug wwan0
iface wwan0 inet ppp
    provider soracom

動作確認

syslogの結果を機能別に分割しました。

1. USBデバイスの認識と、CD-ROMのイジェクト部分

この辺は3-1の１行目による動作です。

wwan0としてネットワークを起動する

3-3.でwwan0とpppconfigの接続部分がうまくできていないと、この辺りで止まります。
また、初期起動時はpppを自動で起動してくれない可能性があるので、
その時はを実行してみてください。

sudo pon soracom

そして、ここから下は「2-3」のスクリプトが動いています。
最後にIPアドレスが表示されたら、インターネットに接続されたということです。
