Hi,
got this turnaround from Lee: it seems there's a bug in ANP, try the following procedure, with mine works every time (boring but working).
Goto configuration, sensors, FLARM.
Tick off the sensor (form green to White)
goto pin code, delete the value and reenter 6001
goto IP Address, delete the value and reenter 192.168.1.1
goto Port number, delete the value and reenter 2000
Tick on the sensor, it will connect immediately.
Unfortunatelly you have to do this every time you start ANP.
Please write something to Xample FB page about this, the more they receive bug notes the better they will improve it in next release.
