MC7455 - QMI problems when host resumes from sleep

[jyijyi]

@mom

I’ve also tried using MBIM instead of QMI (AT!USBCOMP=1,1,100D) → This works but MBIM seems to be slower than QMI.

have you tried QMI over MBIM interface?
e.g.
sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy --device-open-mbim --nas-get-signal-strength

BTW, are you using this method to ask module to go to suspend mode?

QMI interface unresponsive for first command

I tried selective suspend setting on other module SL808x. see if this document can be reused: How to test the sleep mode for SL808X under Linux.docx (13.2 KB)
