Connect Wifly RN-171 to my phone (with an adhoc network)

Hi,

I have a problem with this device. I want to connect it with my phone, so I try to make an adhoc network but I do something wrong. I have follow the steps on the guide:

set wlan join 4
set ip dhcp 0
set wlan ssid my_adhoc_network
set wlan chan 1
set ip address 169.254.1.1
set ip netmask 255.255.0.0

But the network doesn't appear in my phone's wifi connections

Can anyone help me, please?

Thank you.
