Debugging your adhoc network

If you have problems using this app, there might be various reasons for that. Here you can find some ideas on finding the cause.

Is your interface really in ad-hoc mode?

In an adb shell, run

/data/data/net.ott.android.adhoc/files/iwconfig eth0

Your output should look something like this:

eth0      IEEE 802.11-DS  ESSID:"AdhocTest"  Nickname:""
          Mode:Ad-Hoc  Frequency:2.462 GHz  Cell: 2A:58:2D:64:A4:F0   
          Bit Rate=54 Mb/s   Tx-Power:32 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Managementmode:All packets received
          Link Quality=5/5  Signal level=-48 dBm  Noise level=-57 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

The important part is "Mode:Ad-Hoc". If, after you enable adhoc networking in the application, mode is still set to "Managed" you might be experiencing an issue where the phone refuses to connect to pre-existing adhoc networks. A possible workaround is to choose a different SSID and only join the network with your other devices after it has been created on the desire.

Cannot ping

If you cannot ping your phone from other systems in the adhoc network, try pinging them first (from the phone). Probably an ARP issue.
