NACK

The RFE type 2 should be working with some additional fixes.
Did you tested connecting to AP with BT paired?

No, I only tested WiFi.

The antenna configuration is different with RFE type 0.
I will ask someone else to fix them.
Then the RFE type 2 modules can be supported.

Good to know that, I'll be patient and wait for a real fix.

It's been quite some time, is support for RFE type 2 ready now?

It looks like this patch should add it:

New firmware (rtw8821c_fw.bin) is also needed. That is available at
