Hi Xingxing,
root@iot2000-ebs:/usr/lib/ofono/test# ./activate-context
Error activating /huawei_0/context1: org.ofono.Error.NotImplemented: Implementation not
provided.
This tells me that the gprs context driver has failed to initialize. Do
you have TUN/TAP support enabled in your kernel? Is there a log with
ofono running with debug enabled, e.g. '-n -d' you can provide?
Regards,
