Do you have a wpa_cli and p2p_cli that work (compiled) for Android 5.0 and later? Binaries that work on 4.4 return: "only position independent executables (PIE) are supported."

@buhman I have been using wpa_cli for a while, and it's working great! But now I have hundreds of networks, and I have a hard time finding the network number associated with the ssid that I want to connect to. Is there any way that I can search for a network, or select a network, based on its ssid?

For example, imagine the following:

> list_networks
network id / ssid / bssid / flags
0       jumjee  any     [DISABLED]
1       TG      any     [DISABLED]
2       AlphaBeta       any     [DISABLED]
3       the wand        any     [DISABLED]
4       DRINK ALL CITY COFFEE   any     [DISABLED]
5       StellarPizza    any     [DISABLED]
6       HUB     any     [DISABLED]
<many more networks...>
125     Tullys Free Wi-Fi       any     [DISABLED]
> select_network 75
OK

where network 75 is a network called "foo" (where the ssid is "foo"). It's very hard to find the network number, especially when list_networks seems to limit its output to 125 networks. Is there a command, or script, that I can run that will do something like select_network foo? Or even something like find_network_by_ssid foo and will return "75"?

@LukeSwart That 125 limit sounds awful, have you reported these issues to hostap yet? That surely sounds like a bug, and moreover I agree that the requirement for associated numbers instead of SSID seems like very poor UI design.

My wireless interface does not get assigned an IPv6 link local address (which I am guessing should never be the case). I get to see the correct link-local once in a while but it vanishes after a reboot or network restart. I am using wpa_supplicant with nl80211 driver. I can connect two devices using p2p (wifi direct) and I wish to be able to ping one from another using the link-local IPv6 address.

@modulitos To find the number of a given ssid, you can grep for it in non-interactive mode like so wpa_cli list_networks | grep ssid.
