Ad-Hoc Wi-FI interface wireless channel

I've been trying to get my machine to work with Wi-Fi Direct and also ad-hoc mode. I have two dongles, one for each mode. I'm following this tutorial on how to set up wifi ad-hoc: WiFi Ad-hoc Network *edit* I followed the following steps: I modified the /etc/network/interfaces document to be the following: auto wlan0 iface wlan0 inet static address 192.168.2.30 netmask 255.255.255.0 wireless-channel 1 wireless-essid IBSSNetwork wireless-mode ad-hoc wlan0 was my adapter for IBSS mode and wlan1 is my adapter for Wi-Fi direct. I also enabled Wi-Fi direct in the wpa_supplicant configuration. My other computer that I'm trying to communicate with using ad-hoc had the following in the /etc/network/interfaces document: auto wlan0 iface wlan0 inet static address 192.168.2.31 netmask 255.255.255.0 wireless-channel 1 wireless-essid IBSSNetwork wireless-mode ad-hoc From this configuration, I can ping each computer but I cannot create a Wi-Fi direct network. Now I change the /etc/network/interfaces document to be auto wlan0 iface wlan0 inet static address 192.168.2.30 netmask 255.255.255.0 wireless-channel 7 wireless-essid IBSSNetwork wireless-mode ad-hoc and auto wlan0 iface wlan0 inet static address 192.168.2.31 netmask 255.255.255.0 wireless-channel 7 wireless-essid IBSSNetwork wireless-mode ad-hoc and after rebooting the computer, I can no longer communicate via ad-hoc between computers, but I can create a Wi-Fi direct network on my first computer. *end edit* And I'm able to get the Wi-Fi direct and Wi-Fi ad hoc to work independently but not simultaneously. Here's my problem: When I follow the guide and set the wireless channel to 1 and I use wpa_cli - the p2p-dev-wlan1 interface does not show up. When I change the wireless channel in the /etc/network/interfaces document, I can't ping the other computer on the Ad-hoc network. **So my question is, what is blocking me from using both interfaces simultaneously and why can't I set the Wi-Fi ad hoc network to another channel and still communicate with other devices?** Thanks!
