=====PC Engines APU - Arch Linux - Huawei MU609 miniPCIe=====

====Configure Huawei MU609 miniPCIe====
  * Install minicom. <code># pacman -S minicom</code>
  * Add yourself to the ''uucp'' group.
  * Check to see if device is recognized. <code># lsusb |grep Huawei
Bus 002 Device 002: ID 12d1:1573 Huawei Technologies Co., Ltd. 

dmesg |grep CDC
cdc_ether 2-1:2.0 eth3: register 'cdc_ether' at usb-0000:00:13.2-1, CDC Ethernet Device, 00:a0:c6:41:37:70</code>
  * Determine USB tty's.<code># ls /dev |grep -i ttyusb
ttyUSB0
ttyUSB1 
ttyUSB2
ttyUSB3
ttyUSB4</code>
    * **ttyUSB0**: MODEM port: simulated using USB, for AT command interaction and establishing data connection.
    * **ttyUSB1**: DIAG port: simulated using USB, for DIAG (diagnostic) command interaction (mainly used to debug modules at present).
    * **ttyUSB2**: PCUI port: simulated using USB, for AT command interaction only.
    * **ttyUSB3**: GPS NMEA port: simulated using USB, sending unsolicited indications for NMEA positioning data only.
    * **ttyUSB4**: GPS Control port: simulated using USB, for GPS AT command interaction only.
    * **eth3**: ECM port: for establishing communication connection.
  * Connect to the gsm module. <code># minicom -s</code>
  * Go to 'Serial port setup' -> 
    * Serial Device: **/dev/ttyUSB2**
    * Bps/Par/Bits: **115200 8N1**
  * Go back and then to 'Modem and dialing parameter setup'
    * Clear init string and reset string.
  * Select 'Save setup as dfl'.
  * Select 'Exit'.
  * Check SIM. <code>AT+CREG?
+CME ERROR: SIM PIN required</code>
  * If you see **+CME ERROR: SIM failure** check if the SIM card is inserted and the module is in mPCIe 2 slot.
  * enter SIM PIN. <code>AT+CPIN="1234"
OK

^SIMST: 1

^SRVST: 2

AT+CPIN?
+CPIN: READY

OK</code>
  * Check status operator selection. In this case; 0=automatic, 0=long alfanumeric, string, 2=current. <code>AT+COPS?
+COPS: 0,0,"simyo",2

OK</code>
  * Check network status. 0=report off, 1=registered<code>AT+CREG?
+CREG: 0,1

OK</code>
  * Query signal strength. [[http://m2msupport.net/m2msupport/atcsq-signal-quality/|Good signal strength]] here: -79 dBm (17 * 2 – 113).<code>AT+CSQ
+CSQ: 17,99

OK</code>

====Install and configure gammu (optional)====
<code>

# pacman -S gammu dialog
# gammu --identify
# gammu --networkinfo
# gammu --monitor 1
# echo "Testing a test." | gammu --sendsms TEXT +31623456789

sudo mkdir /var/log/gammu
sudo chown root.uucp /var/log/gammu
sudo chmod 775 /var/log/gammu

gammu-config

cat ~/.gammurc 
port = /dev/ttyUSB2
connection = at
synchronizetime = no
logfile = /var/log/gammu/gammu.log
logformat = textall
</code>


====Internet connection using cdc_ether device====
<code>
dmesg |grep cdc_ether
[   13.265612] cdc_ether 2-1:2.0 eth3: register 'cdc_ether' at usb-0000:00:13.2-1, CDC Ethernet Device, 00:a0:c6:41:37:70
[   13.265743] usbcore: registered new interface driver cdc_ether
[   13.705124] cdc_ether 2-1:2.0 enp0s19f2u1c2: renamed from eth3

Configure NDIS dialing, and APN:
echo "at^ndisdup=1,1,portalmmm.nl" >


at^ndisdup=1,1,"portalmmm.nl"

dhclient -v enp0s19f2u1c2


</code>
====Internet connection using netctl====
<code>
pacman -S ppp 
cp /etc/netctl/examples/mobile_ppp /etc/netctl/
vi  /etc/netctl/mobile_ppp
netctl start mobile_ppp
</code>
