Hi, I tried to set up the Sigfab Cellular IoT Kit (LTE-M) with the libqmi procedures(Setting up a data connection over QMI interface using libqmi) However, while the previous steps go well, the command “sudo udhcpc -q -f -i wwan0” cannot discover and report the following error and cannot config the wwan0 interface. The modem I’m using is the ME910C1-WW from sigfab kit.
… The qmicli shows a connected network
