Hi,
I’m using the tutorial below to use the 3G on my Linux colibri-imx7 4.1.15.
The connection is always terminated with the message “Hangup (SIGHUP)” :

I’m using the same carrier (vivo) and modem from the tutorial.
I’ve read about some driver missing.
cat toradex_imx_4.1.15_1.0.0_ga/.config | grep PPP
CONFIG_PPP=y
CONFIG_PPP_BSDCOMP=y
CONFIG_PPP_DEFLATE=y
CONFIG_PPP_FILTER=y
CONFIG_PPP_MPPE=y
CONFIG_PPP_MULTILINK=y
CONFIG_PPPOE=y
CONFIG_PPPOL2TP=m
CONFIG_PPP_ASYNC=y
CONFIG_PPP_SYNC_TTY=y
I know this issue is Linux related, but I need some help on how to debug deeply because I am stuck with this error.
Best regards,
João
