Hello
I am struggling to configure a modem Huawei E3531 on HassOS V5.5 (64 bit on Rpi4) ? I know, it is still in development…
but anyone have it working (or another model/brand) ? I have 3 ttyUSB, configure the SMS integration with /dev/ttyUSB0 or 2 but when I try to send a sms I have a “UNKNOWN ERROR” (see error message below)… Not easy to get the root cause of a unknown error…
I have the feeling that the modem is unable to connect to the network (as the green light is flashing two times every two seconds). But when I connect this modem on another Pi4 running raspbian, everything is working fine… Drivers in HassOS V5.5 not finalized yet… Here is the error when I try to send a SMS:
