basicUDP sample hangs on GSM_MODE

theodore.tzanetos · October 28, 2020, 5:26am

Hello,

I followed the setup guide for the IoT Application Shield, and the PPP installer guide, registrered the super SIM on the connect.sixfab.com website, and the repo installer, but when i try to run

pi@raspberrypi:~/Desktop/Sixfab_RPi_CellularIoT_Library/sample $ python3 basicUDP.py

the program hangs on the following:

Modem configuration : GSM_MODE
Trying to connect base station of operator…

Also is there any issue with stacking this shield on top of the UPS shield? Can both be connected concurrently? I see no conflicting signals on the pinouts.

Thank you!

Hi @theodore.tzanetos,

Can you ping using the PPP interface? - ping -I ppp0 -c 5 8.8.8.8

No, you can stack it on the UPS HAT.

For UDP connection, please follow the tutorial here.

There is no ppp0 interface. After rebooting, and running sudo pon, when i run ifconfig i get

Please follow the steps below for the PPP connection and setup steps:

theodore.tzanetos · October 28, 2020, 11:01pm

I did follow both of these again, just now. It still creates a wwan0, not a PPP0 interface

During the PPP install.sh script, i enter the following
3 (Cellular IoT App Shield)
1 (GPRS/EDGE)
super
n
ttyUSB3
Y

Could you please provide the output of the following command?

ls /etc/ppp/peers/
lsusb
dmesg | grep tty
sudo pon

After a fresh reboot, running your commands results in the following:

I have learned that in order to change the output, I need to run something like the basicUDP.py script which disables and enables the BG96. Somehow that configures the ttyUSB3 port. See below the change in the output. I kill the script once it hangs at the GSM_MODE output line, and then re-run your commands which seems so succeed in some way.
