Please help me after upgraded my 4G lte modem from 9001 to 9011 I’m not able to make calls and run internet simultaneously, if I trying to run modem manager for calls internet goes down and visa-versa, and while making calls the application drops the call in system but runs in background, i tried to find a way to downgrade to 9001 but not able to find the firmware file from anywhere.
If someone knows how to solve this problem please help me out
Welp, sorry you got fooled into thinking the 9011 firmware is an “upgrade”. 9001 user here, and my modem’s running perfectly fine.
If Clockwork’s Github is to be believed in, there’s no going back to the previous firmware without risk of bricking the module.
Also, it’s kind of normal for your LTE connection to drop when using cellular for calls. For you to use cellular for both calls and data at the same time, your calls need to be on what’s known as voice over LTE (VoLTE). Your OS, modem, and cellular network must support VoLTE before you can take advantage of that.
Nevertheless, first off, search is your best tool in this forum. Use it.
How did you make phone calls ?
using AT commands or modem manager?
I’ve tested the 4G modem with 9011
I made calls by
echo -en "ATD1301234567;\r\n" | sudo socat - /dev/ttyUSB2,crnl
1301234567 is just my example phone number.
and while calling , I do can still open browser to watch videos and the ping tests worked ,too
ping -I usb0 8.8.8.8
I also checked the output of ifconfig
normally I have an usb0 and a ppp0 both in ifconfig
mmcli can see the 4G modem ,too
when I hung the call ,there is a chance internet got issue, I found out that the 4G modem and Network manager will clear the /etc/resolv.conf for a little short while ,normally you won’t notice this.
After this short while , /etc/resolv.conf got nameserver back again, everything goes well
I use
echo -en "AT+CHUP\r\n" | sudo socat - /dev/ttyUSB2,crnl
echo -en "ATH\r\n" | sudo socat - /dev/ttyUSB2,crnl
to hung calls
I hope this can be helpful
Best regards
I installed GNOME Calls from Flatpak which make it easier for me to make calls all I have to do is enabled the modem(uconsole-4g-cm4 enable) and that’s it.
Now when I enable my modem it’s shows the internet via ethernet usb0 but GNOME calls shows no Voip is modem is available, and when I start the modem managar for calls then internet goes down.
How about open a terminal
when you got internet via usb0
try use
echo -en "ATD1301234567;\r\n" | sudo socat - /dev/ttyUSB2,crnl
replace 1301234567 with your real target number
for testing to see if it is true that your 4G modem can not have internet and calling simultaneously
Yes I tried this AT command to my target number but nothing happens I recieve no call on my mobile and also tried to call from my number to the SIM number in the modem and, used the AT command to answer the call as mentioned in this link How to make phone call send sms with 4G extension · clockworkpi/uConsole Wiki · GitHub
The call instantly drop after picking up.
