Make sure to use a SIM card with full access to the mobile network.
## Installation
Clone the repository:
```
mkdir ~/git/ && cd ~/git/
git clone https://git.spirirobotics.com/dchvs/eg25-g.git
cd eg25-g/
```
Create udhcpc directories, copy in the script, and give it execution permission:
```
sudo mkdir -p /usr/share/udhcpc
sudo mkdir -p /etc/udhcpc/
sudo cp quectel-CM/default.script /usr/share/udhcpc/
sudo cp quectel-CM/default.script /etc/udhcpc/
sudo chmod +x /usr/share/default.script
sudo chmod +x /etc/udhcpc/default.script
```
Create a udhcpc symbolic link:
```
sudo ln -s /bin/busybox /bin/udhcpc
```
Build the application:
```
cd quectel-CM/quectel-CM
make
```
## Running
The following command launches the package, with [apn-name] being substituted with the APN of the wireless provider. For BICS, the APN is bicsapn. To run this in the background, add & to the end of the command.
```
sudo ~/git/eg25-g/quectel-CM/quectel-CM -s [apn-name] &
```
## Troubleshooting
If the modem is correctly connected to the system, the following command will show the GSM modem attaching to ttyUSB0, ttyUSB1, ttyUSB2, and ttyUSB3:
```
dmesg | grep GSM
```
If the modem has successfully connected to a tower and is being served an IP address, then the following command will show an IP address being served:
```
ifconfig eth1
ping -I eth1 www.google.com
```
