Base HAT not connecting internet

Raspberry Pi Network HATs 3G/4G&LTE Base HAT
1

Dear all,

I have been trying to use Raspberry Pi 3G/4G & LTE Base HAT with EC25-A module and Twilio sim card that came with HAT. I have been trying to make QMI Interface work with Base HAT. I registered and activated the sim card via twilio.

I follow the instructions through tutorial. I didnt have any error till the end of process, which is #12 at this tutorial. However, when I tried to connect the internet through terminal buy typing sudo ./quectel-CM -s internet, it doesn’t seem to connect internet and I am getting the following error “udhcpc: no lease, failing”.

I would like to also note that I had problem with activating my Twilio account and registering my simcard. I have communicating with Twilio support to solve the issue. They said I need to give more details regarding to my project. I did and it is activated again, but I am still not able to connect internet. Is there anyone have had the same/similar issues while setting up the Base HAT?

Also, I am getting the blue LED blinking on my Base HAT, I also tried to use my AT&T sim card that I am using for my cell phone, it also didn’t work.

Thanks for the help,
Dervis

@dervis.gursoy ./quectel-CM -s “YOUR APN” , dont put internet if your APN name is not “internet”

@antoine.egho I think the APN must be “wireless.twilio.com” (please correct me if I am wrong), so in this case, I am doing sudo ./quectel-CM -s wireless.twilio.com , but it is giving me exactly the same error as before. Any idea?

Also, I tried twilio sim card with my cell phone, it did connect the internet, so it seems the problem is not because of Twilio.
Thanks

Hi @dervis.gursoy, i’m pretty new to this, but you are right twilio’s apn is indeed wireless.twilio.com

please post the complete log. you can use as well -f “filename.log”

antoine, I am having the same issue. I just received the Raspberry Pi 4G/LTE HAT kit today and have been trying to get it working with Twilio. Here is my log. Can you please help?

Have you gotten an answer to this yet? I’m having the same issue with the EC25 and Pi 4.

I can’t remember where I found this, but it certainly fixed the problem.

Edit the /etc/dhcpcd.conf file with nano, at the end add denyinterfaces wwan0

This stops udhcpcd arguing with dhcpcd and so makes the GSM module able to get an IP address
