I checked the interface number from the ofono logs and got 04
Dec 22 22:14:48 PinePhonePro ofonod[1346]: plugins/udevng.c:setup_qmi_qmux() 
qmi: /dev/cdc-wdm0 net: wwan0 kernel_driver: qmi_wwan interface_number: 04

But when I run the above command all i get is
[root@PinePhonePro defaultuser]# qmicli --device=/dev/cdc-wdm0 --wda-get-data-
format=ep-type=hsusb,ep-iface-number=4
error: couldn't get data format: QMI protocol error (48): 'InvalidArgument'
[root@PinePhonePro defaultuser]# qmicli --device=/dev/cdc-wdm0 --wda-get-data-
format=ep-type=hsusb,ep-iface-number=04
error: couldn't get data format: QMI protocol error (48): 'InvalidArgument'
