Hello, I have problems to get WiFi P2P on a Nanopi NEO Air board up and running. The board uses a AP6212 WiFi module with the BCM4343A0 SDIO chipset (ID: 0xa9a6). Connecting to an AP as normal WiFi client is working without problems. I can also discover other WiFi P2P nodes using wpa_cli p2p_peers, but when I try to connect using wpa_cli p2p_connect the connection attempt fails with the following log. Are there any known problems with this kernel/wpa_supplicant combination for this chipset? Why the interface type can't be changed to P2P_CLIENT? I also tried to use the "p2pon" driver option but when I try to start wpa_supplicant on the P2P interface I get an kernel crash.
