Hello, I adapt EC20 r2.0 module on mtk9632 platform, Android version is 9.0, kernel version is 4.9.
In fact, EC20 is written on the module. I use lsusb to check vid:pid It is: 2c7c: 0125, so it should be EC20 r2.0; now, I want to realize PPP dial-up Internet access,My operation steps are as follows：
1.I configured according to 3.2 and 3.6 of the document:《Quectel_WCDMA<E_Linux_USB_Driver_User_Guide_V1.8.pdf》, and copied files in “linux-ppp-scripts_V1.2.zip” to the directory of the development board: /etc /PPP/peers
2.then, create the directories:/var/lock and /var/run
3.Check the network status with at command:
4.Then I use “pppd call quertel -ppp” to test PPP dial-up Internet access, and the print is as follows:
pppd call quectel-ppp
pppd options in effect:
