Is there a way to list the connected devices on my wifi access point?

I have an Angstrom Linux device acting as an access point, running hostapd, dhcpd, which works fine. Can I get a list of devices connected to the Wi-Fi? I know I can get the DHCP leases, but I need to know which devices connect through wlan0. I've tried this (iwlist has options): iwlist wlan0 ap iwlist wlan0 accesspoints iwlist wlan0 peers but all return: wlan0 Interface doesn't have a list of Peers/Access-Points iwconfig, iwgetid, iwpriv and iwspy are also present in /sbin, but don't seem to have options to display the client list.
