2- How to connect the mobile broadband?
OS: JetPack 4.6
In this blog post, we will connect mobile broadband with Quectel EM06-E LTE GSM module. First, we will enable M.2 Key-B slot’s power. Then, we will connect to the Internet with this mobile broadband.
Hint: In this tutorial, we connected our GSM antennas on this module's M & D ports.
Connect the Quectel EM06-E LTE GSM module & SIM card on DSBOARD-NX2. Then, power up the system.
You can see the mounting direction of nano SIM card on the connector (nano SIM - micro SD card) below.
Open a terminal and type these commands below (the Key-B power pin for Xavier NX is 421):
sudo echo 421 > /sys/class/gpio/export
sudo echo out > /sys/class/gpio/gpio421/direction
Open a terminal and type these commands below (the Key-B power pin for Xavier NX is 440):
echo 440 > /sys/class/gpio/export
echo out > /sys/class/gpio/PQ.05/direction
Then, type “lsusb” after 10 seconds later to check the Quectel GSM module powered on.
After the GSM module powered up, the PIN code will ask (if it was not disabled).
Type the PIN code and unlock the SIM card.
Open the network connection menu at the top of the launcher and click the “Edit Connections...”.
Press the plus button and select “Mobile Broadband”.
Select “Quectel EM06E” mobile broadband device and continue to the next step.
Select your country/region and continue.
Select your provider and continue.
Select your billing plan and continue.
Look up the network configuration and apply it.
Then save the generated connection to connect on it.
As you can see that, our mobile broadband connection established.
Finally, let’s test it on browser.
