Re: brcmfmac: BCM4343A0 P2P mode problem

Thank you for your support. Yes, correct SDIO 0xA9A6 is BCM43430 I was confused by the naming of some firmware files.

What firmware version/file shall be used for this chipset/driver combination?
Currently I'am using the firmware file "fw_bcm43438a0_p2p.bin" from here https://github.com/BPI-SINOVOIP/BPI_WiFi_Firmware/tree/master/ap6212.

I have set the driver parameter "use_p2p_group_interface=1" as you recommended, and now I see following error messages at the kernel log when I try to setup a P2P connection.
