Need Help Restarting 3372H Dongle via Command or API on Ubuntu Server

I've also searched for APIs on GitHub, but I haven't found one that works well for my setup.

Why? There is a lot of python/bash scripts that cover almost every needed function: restart, data on\off, switch mode 2g/3g/4g/auto, read/send SMS/USSD etc.

# Build the switch request

except Exception as ex:
print("Failed to switch modem..")
print(ex)
return False

# Pass '0' for off

What's restart?

1. Huawei API: Some Huawei modems support a set of APIs that allow for various controls. Although not all commands are supported on all devices, it might be worth investigating.
   • First, see if you can access the modem's API at http://192.168.8.1/api/device/reboot (or the appropriate IP for your dongle). If you can access this URL, you might be able to send a POST request to it to reboot the modem. You can use tools like curl for this.
     bashCopy code
     curl -X POST http://192.168.8.1/api/device/reboot
   • If the above method works, then you can easily include it in a bash script.
2. USB Modeswitch: Another approach is to use the usb_modeswitch tool, which is designed to switch modes of USB devices. You might be able to simulate a reconnection of the dongle by switching its mode.
   Install it with:
   bashCopy code
   sudo apt install usb-modeswitch
   Once installed, you can try switching the mode of your dongle and then switch it back. This might make the device disconnect and reconnect, simulating a physical replug.
3. Network Manager CLI: If you're using NetworkManager, you can control your connections using the nmcli tool.
   • First, list all your connections:
     bashCopy code
     nmcli con show
   • Then, you can disconnect and reconnect:
     bashCopy code
     nmcli con down id '<Your Connection Name>'
     nmcli con up id '<Your Connection Name>'
4. Physically Restart the Device: If none of the software solutions work, and if your setup allows, you could use a programmable power switch that can turn off and then turn on the power supply to the dongle. This would be akin to physically unplugging and plugging the dongle back in. There are USB hubs available with individual port power switches which can be controlled programmatically.

Always remember to be careful when applying these methods, especially when automating, as repeated rapid reconnections could cause wear on the dongle or draw unnecessary attention from your ISP.
