Quectel EC25 Mini PCle 4G/LTE Module not connecting


I also have the Quectel EC25-E (for Europe, I am near Paris with Orange as telecom operator) Mini PCle 4G/LTE with Raspberry Pi 3G-4G/LTE Base Shield V2. I’m not able to connect.I followed the steps of the tutorial of ppp conection, but when I write in command “sudo pon” I get the following error. ( I have on red light of power and the blue light is blinking).

I am using :

  • Raspberry Pi 3G-4G/LTE Base Shield V2
  • Quectel EC25 Mini PCle 4G/LTE Module – EC25-E
  • Two mini antenna are plugged to the EC25 module.

For the raspberry, I use the default power supply furnished with a raspberry engraved on it.
For the base shield, I plug the mini USB adaptator to a USB port of the raspberry Pi.

I have also inserted a classic SIMcard for a 4G internet access. It works very well while I use it in a common Huawei wifi mini-router.

I live in Paris, and the signal use to be very clean and strong where I test the sixfab device.

I use a SIM that I am sure it is operational ; I use it with a Huawei 4g hotspot router (like the 4G E5786) and it works very well.

It look like this (in french) : https://assistance.orange.fr/cle-domino/tous-les-cles-et-dominos/installer-et-utiliser/mettre-en-service/domino-huawei-4g-e5786-configurer-un-profil-de-connexion_64464-65311

login : orange
password : orange
APN : orange.fr

When I try … APN : “orange.fr” with …

# noauth
user “orange”
password “orange”

pi@raspberrypi:/etc/ppp/peers $ sudo pon
/usr/sbin/pppd: The remote system (3gppp) is required to authenticate itself
/usr/sbin/pppd: but I couldn’t find any suitable secret (password) for it to use to do so.

Thanks in advance for the help.

I solved the problem by removing the # before the line “noauth”, and I also removed USER “orange” + PASSWORD “orange” in /etc/ppp/peers/provider.

Then I wrote this line “orange * orange -” in /etc/ppp/pap-secrets.
