[aokblast]

Summary

Currently, this patch haven't been test as I broke the wifi module when I was testing because of the incorrect parsing algorithm.

@wulf Hello, I see you are the author of writing this userspace program. Could you please tell me how you test it safely?

[wulf]

I am about to commit V2 firmware support. It worked for me with at least one 8852CE adaptor. just test it.

It broke bt adaptor for me at first early version run too due to bug in rtlbt_load_fwfile() which is fixed in my version now

Let me clarify two things:

1. You have 1 patch for v2 header so I can abandon this patch?
2. The way you test the the v2 is breaking the dongle and get a new 1?

No. Switching power off and on on laptop appeared to be enough to bring radio module back to life

What is a model name of your dongle?

[aokblast]

I use rtl8852be. It is a pcie wireless card.

Some laptops powers radio module even they are switched off. You may try to reinsert wireless card or discharge battery.
