Nexus 5 - hostapd - aireplay-ng deauth

Hi

I have a Nexus 5 with Nethunter 3.0, i use a TP-link TLWN722N adapter and create a wireless access point with hostapd.

Now if i wanted to deauthenticate or jam another access point using aireplay-ng, would this be possible on the same wireless interface, because aireplay-ng needs the wlan to be in monitor mode, but it is already running the soft AP with hostapd.

Can somebody help me with a way around this??

Also is it possible to use an OTG usb hub with another wirless adapter, so i will have 2 external wifi adapters?? does the nexus 5 support this.

I look forward to hearing your replies.

Thanks
