Hello, I think my problem was just a firmware version issue. When I use the firmware file "fw_bcm4343.bin" from here https://android.googlesource.com/platform/hardware/broadcom/wlan I'am able establish a P2P connection. Is this the latest/recommended firmware version for the chipset? Firmware version = wl0: Jul 1 2016 18:02:40 version 7.10.1 (A0 Station/P2P feature) FWID 01-bae8afee >Thank you for your support.
