EC25: udhcpc does not get a lease

IoT Modules LTE Standard Module
1

Hello,

I’m running an LTE module (EC25EFAR06A11M4G) on Linux (Ubuntu 16.04).
My wwan0 interface does not receive a lease via DHCP (udhcpc ver. 1.22.1). I have set the ip-raw mode and there is no other dhcp client running on the system.

What could be the reason?

Try this cmd ：

echo “Y” > /sys/class/net/wwan0/qmi/raw_ip

If you use the qmi_wwan_q from Quectel or QConnectManager version later than 1.6.0.16, you need’t to do that.

Hi Bean.Wang-Q,

I had set the raw-IP-mode, but that didn’t solve my problem.

Have you stoped the ModemManager?
