iNavX is great, but I have found a network bug on the iPad IOS 3.2, iNavX v3.1.6.
When I try to download a new NOAA chart while connected via wifi, more often than not iNavX will sit there for a few minutes and then say:
"Warning Unable to Download ... (timed out)"
The download is successful about 2/5 times.
The bug is exacerbated when I try to download multiple charts, for example selecting "Yes, All USA East". The first one or two charts download, then the connection times out again.
I have tried multiple wifi networks on different days in various locations, with identical results.
The same iNavX version on my iPhone, connected to the same wifi network, works fine.
HOWEVER, if I turn off wifi on the iPad and turn on cellular data, IT WORKS CORRECTLY WITH NO DELAY AND NO TIMEOUTS!
Hence, it seems likely that iNavX is having trouble making a network connection. Presumably this is in the network code, and the packets are never moving down the TCP/IP stack.
In order to test this, I installed Firewall IP. The problem was unchanged but, interestingly, Firewall IP never pops up a message about an outgoing connection on the occasions that iNavX is timing out, lending support to the notion that the iNavX software is failing to generate any packets. On the times that iNavX does not time out, Firewall IP correctly pops up a rule box, and then the chart download proceeds normally once I have allowed the connection.
The problem is severe because it is making it very difficult to download all of the NOAA charts for an area.
