sms sending failed - JoWo - 12.09.2025
Hello everyone,
I'm having a problem sending SMS messages via a USB modem. I've tried it on a SpaceLYnk (v. 3.0.0) and a LogicMachine (20241211). I've also tried various USB modems, but I always get the same error.
The USB device appears in the system log, but it's not listed under serial ports.
The SMS script I'm using is from here: https://kb.logicmachine.net/notifications/sms/.
I'm currently stuck for what else I could try.
I would be very grateful for your help.

Which other modems have you tried? It might be possible to update the relevant package so the USB mode change happens correctly but it will only work in LM.

I have also tried a Huawei E3531 (worked until I updated to Firmware 3.0.0 on Spacelynk) an the ZTE MF710M. Maybe the firmware version is the problem?

Can you provide System log for other modems?

Hello
I think the USB Mode change is the Problem. I have found this entry in an other Forum https://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=1295
I have tried to change the usb-Mode on my Windows pc and it works correctly. The device id changed to 1442 and the device is displayed as a serial device. In SL the productID changed only to 14dc.
Is there a solution for this problem? For now it is enough if it works on LM maybe in futur there is a Solution for SL to.
Thanks

Thanks for the fast answer.
i have installed the package. But no change the modem do not change the usb mode. After a reboot the device is only found as a USB Mass storage device
If i unplugged the device and plugged in again
After uninstall the package and reboot
I am happy about every solution.

Without the package the modem won't switch to the required mode. Install the package again then run this script once:
Code:
data = [[
return {
messages = {
"55534243123456780000000000000011062000000100000000000000000000"
},
devices = {
['12d1:1f01'] = {
['*'] = { msg = {0} }
}
}
}
]]
io.writefile('/lib/usbmode/data.lua', data)This will use a different switch message for your modem. Seems that different modem firmware versions require a different message. You can try different messages from the post that you've linked before.
