Packet statistics of EM9293 and EM7431

1

The Host can use EM9293 or EM7431 to connect to internet and then host can ping Google DNS server(8.8.8.8), next I use command “mbimcli -d /dev/cdc-wdm0 --query-packet-statistics” to get packet counter of modem, but all packet counter of modem are zero, how do I to get the packet counter of modem?

2

do you see any change in ifconfig command?

3

Yes, If I use “Ifconfig wwan0”, Tx packets and Rx packets are increased, but I used “mbimcli -d /dev/cdc-wdm0 --query-packet-statistics” , the all packets counter are still zero
