 # Quectel EG25-G GSM Modem
 
-## Kernel Changes
+## Quectel Setup
-This package requires the Spiri Mu kernel and modifications to the following files:
+The Quectel should be conencted to a ConnectTech's Elroy board.
-* drivers/usb/serial/option.c
+The Quectel module requires to connect the antenna on the MAIN and GNSS sockets.
-* drivers/usb/serial/usb_wwan.c
+Make sure to use a SIM card with full access to the mobile network.
-* drivers/net/usb/qmi_wwan.c
-* drivers/net/usb/Makefile
-
-It also requires these new files:
-* drivers/net/usb/GobiUSBNet.c
-* drivers/net/usb/QMI.c
-* drivers/net/usb/QMI.h
-* drivers/net/usb/QMIDevice.c
-* drivers/net/usb/QMIDevice.h
-* drivers/net/usb/Structs.h
-
-All these modifications and additions are part of the Spiri Mu kernel. The files are represented in https://git.spirirobotics.com/Spiri/mu_kernel_sources as symlinks from this repository.
 
 ## Installation
+
 Clone the repository:
 ```
-cd ~/git
+mkdir ~/git/ && cd ~/git/
-git clone https://git.spirirobotics.com/Spiri/mu_packages.git
+git clone https://git.spirirobotics.com/dchvs/eg25-g.git
-```
+cd eg25-g/
-
-Create a udhcpc symbolic link:
-```
-cd /bin
-sudo ln -s busybox udhcpc
 ```
 
 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 ~/git/mu_packages/eg25-g/default.script /usr/share/udhcpc
+sudo cp quectel-CM/default.script /usr/share/udhcpc/
-sudo cp ~/git/mu_packages/eg25-g/default.script /etc/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 ~/git/mu_packages/eg25-g/quectel-CM
+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/mu_packages/eg25-g/quectel-CM/quectel -s [apn-name]
+sudo ~/git/eg25-g/quectel-CM/quectel-CM -s [apn-name] &
 ```
 
 ## Troubleshooting

+#### Kernel Changes
+The Driver for the EG25-G Quectel module consists has the following structure on the Kernel space side, for interfacing it and adding its Network packets transmisions on Kernel.
+
+.
+├── kernel
+    └── kernel-4.9-spiri
+        └── drivers
+            └── net
+                └── usb
+                    ├── GobiUSBNet.c
+                    ├── Kconfig
+                    ├── Makefile
+                    ├── QMI.c
+                    ├── QMIDevice.c
+                    ├── QMIDevice.h
+                    ├── QMI.h
+                    └── Structs.h
+
+In order to add the Driver to the Kernel, the following reference Kernel files are patched:
+
+* drivers/usb/serial/option.c
+* drivers/usb/serial/usb_wwan.c
+* drivers/net/usb/qmi_wwan.c
