ios - iPad<->Device Ad-Hoc network failures using Auto IP addresses -


we using ipad make ad-hoc wireless connection our proprietary device. dhcp not available, using addresses in auto-ip range. user selects device list of wireless networks on ipad , twenty seconds later, dhcp fails , auto-ip address assigned. device has fixed ip address of 169.254.20.10.

the problem having time time, ipad loses it's ability connect device. issue appears happen quicker ipad 4th generation , ipad mini. combination of switching wireless network on ipad , ad-hoc network and/or turning wi-fi off on again fixes issue, ipad needs restarted.

when gets in state, socket errors receive in our app when try unicast 169.254.20.10 or broadcast 169.254.255.255 either 'host down' or 'no route host'. confirmed using app such tools ping device.

any ideas might going on or how fix issue?
