How to configure our Wireless NMEA Products for Wi-Fi and 4G connections

Wireless NMEA Products


Recently we have received a couple of reports that when customers are connected to one of our wireless NMEA products, that they can no longer access the internet via 3G on their iPhone/iPad. This is due to the device thinking that it has a good wireless internet connection and so defaulting to this connection rather than the 3G connection.

This is only present on units produced between Sept 2012 and now, which have our “Access Point” mode firmware (V2.45 or V4.00) in the wireless adaptor.

As it turns out, the fix is fairly simple (just changing one setting in the wireless module) and we have produced a Tech Support Note on how to carry out the fix using a PC, Mac or using a free App on the iPhone/iPad. Please download the Tech Note by clicking here.

We will be incorporating this change in all of our production units in the new year (Jan 2014) but if you already have a unit which is not allowing you to connect to the internet via 3G when you are connected wirelessly to one of our wireless NMEA products, we recommend you to follow the procedure outlined in this Tech Note.

  1. Good day sailors and friends,

    I bought a nice iAIS device (second hand) which I like much as it now can plot the AIS ships on my own made plotter. Just perfect!
    Only it must also possible to access this with android tablet or phone.
    Now I have lot of them and only 1 can find the name ““DY-iAIS-xxxx” and can make connection.
    Only the free “iAIS” (iOnboard for Android) app on play store, cannot get data from it.
    Yes, I did connect GPS to NMEA input and Yes, I can read on NMEA out combi data GPS+AIS.
    On WiFi analyser I can see it is there.
    After long test, I see that IP over Wi-Fi is and that I think is may be the reason why I not find it on my Android Devices..May be someone know??
    I read on the service web that was change from to for 3G problem.
    You can change it by a tool. Now I wonder can I use same tool to change it back?

    1. Hi Johan,

      We need to check the firmware running on the iAIS before we can recommend the optimum settings. It might be quicker and easier for you to return the iAIS for a full firmware and configuration update, which will bring it up to the same spec as our current models.
