Testing The BatNav Raspberry Pi Server
At this point it might be worthwhile checking that the BatNav Raspberry Pi server is
receiving data from the AIS/GPS device(s) you have connected.
From your Android phone/tablet you should now
see a new WiFi network available called BatNav. Connect to this
network.
The default password is batnav123
You will probably get a warning that this connection does not have
internet available. You may ignore this but keep in mind you will not
be able to use the internet on your phone/tablet while using
BatNav
You should disconnect from the BatNav WiFi network when you are no
longer using BatNav so that you
can get online again. It is worth ensuring that the BatNav connection
on your phone/tablet has auto reconnect disabled to avoid it
inadvertently connecting without manually selecting it.
Once connected to the BatNav network, you should now be able to
navigate to this link on your phone/tablet http://192.168.4.1

You should see a screen similar to the one pictured. We can see from this web page that the BatNav server has detected two devices. The first device has received GPS messages and the second device has received AIS messages so both devices are behaving as expected.
You will need to manually refresh this page to see an updated list of the message counts.
Your Raspberry Pi will have the IP address 192.168.4.1 and will be serving data
to the BatNav Android App on port 2001.
These are the values you will need in the next step to configure your phone/tablet.
