CONFIG_USB_NET_HUAWEI_CDC_NCM and CONFIG_USB_NET_CDC_MBIM were not enabled in my build.
CONFIG_USB_ETH_RNDIS was enabled.
I enabled both and re-flashed the kernel and modules.
I see no change. PPP still works; however, Ofono’s test scripts do not find the modem.
Unfortunately our team runs out of ideas. If you really need to use this modem with ofono, I have to redirect you to one of our partners who could do a proper integration.
Hi @jaski.tx, we never did get the issue resolved, and in the end we switched to a different modem manufacturer and used ppp dialing. Thanks for the link to the other post. Will have a look to see if that fits our needs.
I installed gammu on centos7, and usb_modeswitch. the sendsms It works but now it does not work, 12d1: 1f01 change to 12d1: 14db , I can’t detect the Huawei E353/E3131 key as a modem . please help
