4G extension on the uConsole is power down by default
|
|
|
|
## First we need to power on the 4G extension
|
|
|
|
### CM4
|
|
|
|
run `enable_4g_cm4.sh` or `uconsole-4g-cm4 enable`, depends on the version of your os image, both can do the same job
|
|
|
|
Please wait for it to complete, which may take about 20 seconds. Please be patient and try not press ctrl+c.
|
|
|
|
next is **VERY IMPORTANT**, to check the version of your 4G extension by AT commands:
|
|
|
|
```
|
|
echo -en "AT+CUSBPIDSWITCH?\r\n" | sudo socat - /dev/ttyUSB2,crnl
|
|
```
|
|
|
|
we expecting to see **9001**
|
|
|
|
if you are other module number ,eg :9011
|
|
|
|
you don't need any following steps
|
|
|
|
just make sure the SIM card inserted correctlly,and use **sudo ifconfig** to see if there is a **usb0**
|
|
|
|
if there is a usb0,then all is set
|
|
|
|
normally you will have ipv4 and ipv6 address,now you can use 4G card to view internet
|
|
|
|
#### 9001 part
|
|
|
|
use `mmcli -L` to see if there is a modem like
|
|
|
|
```
|
|
/org/freedesktop/ModemManager1/Modem/0 [QUALCOMM INCORPORATED] SIMCOM_SIM7600G-H
|
|
```
|
|
|
|
and if unpack your back shell , you will see a green LED light is flashing on 4G ext
|
|
|
|
### A06 and R01
|
|
|
|
run `enable_4g.sh` or `uconsole-4g enable` depends on the version of your os image, both can do the same job
|
|
|
|
Please wait for it to complete, which may take about 20 seconds. Please be patient and try not press ctrl+c.
|
|
|
|

|
|
|
|

|

|

|
|

|
|
|

|
|
use `mmcli -L` to see if there is a modem like
|
|
|
|
```
|
|
/org/freedesktop/ModemManager1/Modem/0 [QUALCOMM INCORPORATED] SIMCOM_SIM7600G-H
|
|
```
|
|
and if unpack your back shell , you will see a green LED light is flashing on 4G ext
|
|
|
|
## Connect to 4G network
|
|
|
|
for this purpose,we need `nmcli` to create a gsm connection first
|
|
|
|
### find out the primary port
|
|
|
|
```
|
|
mmcli -m any | grep "primary port"
|
|
|
|
```
|
|
you will get like `cdc-wdm0` or `ttyUSB2` , if you got `cdc-wdm0`, we suggest blacklisting some kernel modules by
|
|
|
|
```
|
|
sudo bash -c 'cat << EOF > /etc/modprobe.d/blacklist-qmi.conf
|
|
blacklist qmi_wwan
|
|
blacklist cdc_wdm
|
|
EOF'
|
|
```
|
|
|
|
`ttyUSB2` is what we want,but **cdc-wdm0** is still worth to try if you knew it well
|
|
|
|
### Create 4g net connection and bring it up
|
|
|
|
```
|
|
sudo nmcli c add type gsm ifname ttyUSB2 con-name 4gnet apn [yourapn] gsm.username [gsmusername] gsm.password [gsmpassword]
|
|
```
|
|
|
|
```
|
|
sudo nmcli c up 4gnet
|
|
```
|
|
|
|
then if everything goes right, you will see **ppp0** in `sudo ifconfig` , which means you got an PPPoE connection and an IP address
|
|
|
|
|
|
The connectivity of 4G may vary in different countries around the world, so please make appropriate adjustments based on the situation of your ISP operator, which may require some Linux-related skills.

## GPS
|
|
|
|
We use AT commands to get GPS data
|
|
|
|
### start gps
|
|
```
|
|
cpi@raspberrypi:~ $ echo -en "AT+CGPS=1\r\n" | sudo socat - /dev/ttyUSB3,crnl
|
|
OK
|
|
```
|
|
|
|
### wait about one minute depend on the gps signal,get gps data
|
|
```
|
|
cpi@raspberrypi:~ $ echo -en "AT+CGPSINFO\r\n" | sudo socat - /dev/ttyUSB3,crnl
|
|
+CGPSINFO: 3036.995500,N,12016.782856,E,200224,082124.0,40.5,0.0,
|
|
OK
|
|
```
|
|
|
|
### close gps
|
|
```
|
|
cpi@raspberrypi:~ $ echo -en "AT+CGPS=0\r\n" | sudo socat - /dev/ttyUSB3,crnl
|
|
```
|
|
|
|
make sure the **GPS antenna** is connected to the **GNSS** port on 4G extension
