After serveral days trying i have been not able to connect my Cellular IoT Application Shield to the internet via LTE data service. I have read the tutorials but still don’t understand what i’m doing wrong.
My goal is to enable my rpi to access internet via LTE data service, in order to connect an small web app with my server and send or pull general information via http requests.
Can someone help me find what i’m doing wrong?
More details about my case:
The hardware i’m using:
- Raspberry PI 4
- Cellular IoT Application Shield – LTE-M & NB-IoT & eGPRS (BG96, Firmware: BG96MAR02A10M1G)
- LTE – GNSS Dual u.FL Antenna – 100mm
- Right Angle Micro USB Cable
My laptop operative system is: Ubuntu
For Raspberry pi, i’m using: Raspbian Buster Lite
Providers tested:
- Movistar Panama with FDD LTE 700MHz B28.
- Claro Panama with the same 4G LTE (B28 700 MHz).
SIM Cards used:
1-) Movistar panama SIM card with prepaid normal data. (working fine on regular android phone)
2-) Movistar panama SIM card with prepaid unlimited data for 7 days. (working fine on regular android phone)
3-) Claro panama SIM card with postpaid plan used for a mobile wifi modem. (working fine on the huawei modem)
APN Settings used:
- Movistar: internet.movistar.pa, user: movistarpa & password: movistarpa
- Claro: web.claro.com.pa, user: claroweb & password claroweb
steps:
1-) Parts has been assembled exactly as documented on hardware setup steps at: sixfab docs raspberry-pi-cellular-iot-application-shield-getting-started
2-) Flashing a 32GB sd card with 2019-09-26-raspbian-buster-lite.img & enabling ssh by doing:
cd /media/pc-user/boot && touch ssh
3-) Unplug the USB cable from Cellular IoT App Shield. (in order to start with installation of QMI Interface with Cellular IoT App Shield, documented on: sixfab docs qmi-interface-with-cellular-iot-app-shield)
4-) Installing sd card & sim card to the rpi.
5-) Connecting raspberry pi to my local network via ethernet, and ssh into the rpi… (e.g.: ssh -l pi 192.168.2.104).
6-) Updating rpi: sudo apt update && sudo apt upgrade -y
7-) Installing rpi kernel headers: sudo apt-get install raspberrypi-kernel-headers
Rebooting rpi. (sudo reboot now)
9-) Login back to rpi and download script: wget https://raw.githubusercontent.com/sixfab/Sixfab_RPi_3G-4G-LTE_Base_Shield/master/tutorials/QMI_tutorial/qmi_install.sh
10-) set permission: sudo chmod +x qmi_install.sh
11-) Run script (with module disconnected): (sudo ./qmi_install.sh) everything seems to finish ok, just with several warning messages on finishing the script… so proceeding to reboot.
12-) Rebooting again the rpi & reconnecting the USB cable to the shield.
13-) Login back to rpi and moving into: cd files/quectel-CM
14-) Testing QMI with command: sudo ./quectel-CM which shows the messages:
pi@raspberrypi:~/files/quectel-CM $ sudo ./quectel-CM

[05-09_20:50:05:656] Cannot find qmichannel((null)) usbnet_adapter((null)) for Quectel modules
15-) Manually powerup quectel module by pressing POWEKEY hardward button… waiting few seconds until red led is on and blue led is blinking…
16-) Trying again the QMI with command: sudo ./quectel-CM which shows the messages:

17-) Here is where i get stuck.… It just show a “requestQueryDataCall IPv4ConnectionStatus: DISCONNECTED” and Registration state keep saying “requestRegistrationState2 MCC: 0, MNC: 0, PS: Detached, DataCap: UNKNOW” for ever…
I have tried other stuff like explicit apn & apn with password:
- sudo ./quectel-CM -s internet.movistar.pa
- sudo ./quectel-CM -s internet.movistar.pa movistarpa movistarpa
with same results:

So, i have try all this process several times with different sim cards and LTE data plans… in all cases the result has been the same.
Again i just what to enable my rpi to connect to internet via LTE or Edge or any available band, to access a mini web app which use openvpn to communicate… that’s why i still did not try the PPP tutorial yet…
Do you guys can see anything i’m doing wrong, or missing? or any other suggestion to try?
Thanks in advance for any help!
