PCIe MTPCIE-H5/MTPCIE-BW Developer Guide
1. Verify your wireless account is activated with a data plan. If using a GSM radio like MTPCIE-H5-BW, install
the SIM card.
2. If using a GSM radio, edit /etc/ppp/peers/gsm_chat file and change the APN to match up with the SIM
card
3. Connect the cellular antenna to the MTPCIE device.
4. In the MT100EOCG, enter:
For MTPCIE-H5 devices:
pppd call gsm
5. After 10 seconds, enter ip a in the MT100EOCG to verify the PPP link is up and an IP address obtained.
Setting Wi-Fi Access Point with an MT100EOCG and an MTPCIE
Bluetooth/Wi-Fi
To setup a Wi-Fi access point with an MT100EOCG and an MTPCIE Bluetooth Wi-Fi device:
1. Build corecdp-wifi-ap-image and flash it into the MT100EOCG.
2. Edit /etc/udhcpd.conf to configure the dhcp server.
3. Edit /etc/hostapd.conf to configure access point settings. Configure ssid=<name> with the access point
name. Save hostapd.conf.
4. To start the access point, type ocg-wifi-ap.sh start <desired IP address of AP> on the MT100EOCG. For
example:
ocg-wifi-ap.sh start 192.168.2.1
5. If you run a script like the example, the MT100EOCG acts as a cell router that allows Wi-Fi and Ethernet
endpoints to access the Internet through EOCG’s cellular PPP link. Uncomment the ppd call line for your
device model.
6. Create a wireless network connection on a remote computer and configure it to use DHCP to obtain IP
and DNS addresses.
7. Enable the wireless connection on the computer. Verify that your computer can communicate to the
Internet using MT100EOCG as the access point.
Example Wi-Fi Access Point Script
#!/usr/bin/env bash
echo "Updating DNS, ppp scripts"
echo "nameserver 8.8.8.8" > /etc/resolv.conf
killall pppd && sleep 2
echo "Starting pppd"
#uncomment line below if gsm radio (H5, etc)
#pppd call gsm
#uncomment line below if cdma radio (EV3,etc)
#pppd call cdma
sleep 4
