Sim7600x 4G Hat on Raspberry pi4 does not start

alemalza · June 9, 2021, 8:41am

Hi there
i install openwrt on my raspberry pi4 and i am trying to configure the SIM7600X 4G hat for ppp connectivity https://www.waveshare.com/wiki/SIM7600E-H_4G_HAT
i connect over ssh to my pi4 and do this:

opkg update
opkg install usb-modeswitch kmod-mii kmod-usb-net kmod-usb-wdm kmod-usb-net-qmi-wwan uqmi

i restart my device but then i try if my hat is ok:

uqmi -d /dev/ttyAMA0 --get-data-status

i get no response, cursor stay in waiting but never happen (also if i change the port to /dev/ttyS0)

There something i forgot or i am wrong for have my SIM7600 hat working correctly?

So many thanks in advance

tried using screen or minicom to talk to it, instead ?

alemalza · June 9, 2021, 9:36am

..sorry but i am new about this kind of configurations. What did yuou mean with minicom? i have to install a software with opkg?
Thanks in advance

frollic · June 9, 2021, 9:37am

yes, exactly.

alemalza · June 9, 2021, 9:43am

ok i installed scren and when i try:

screen /dev/ttyAMA0 115200

i get:

ERROR ate:: not found

frollic · June 9, 2021, 9:45am

you get ate when you do what ?

alemalza · June 9, 2021, 9:48am

Sorry but i don't know what ate is/mean and how i can get it

alemalza · June 9, 2021, 9:49am

But if i try with /dev/ttyS0 i get no error but cursor lighting without allowing me to write any command

Start from cat /sys/kernel/debug/usb/devices
Then

ls -l /dev/cdc*
ls -l /dev/tty*

my hardware is not an USB, is an hat over GPIO raspberry pins

So many thanks

My understanding that you need USB connection between the module and the host (RPi). Your issue has nothing to do with OpenWrt yet.

It looks like you can avoid using USB but you will need to 'release' the RPi serial port first.
In either case you cannot use uqmi.
