No, the device does not need to be configured. If you’re connecting it to an NMEA system the QK-A026 will automatically set its own Baud rates. You may have to change them if you have a specific need. Then you would need a windows PC to configure the Baud rates.
Configuration is also needed if you wanted to put the QK-A026 in station mode. This would give you the benefit of not having to connect to the QK-A026 Ad hoc. Leaving your wireless device free to connect to the internet.
By tonight or tomorrow morning we will be selling a GPS antenna as an accessory to certain devices. You will be able to buy one from us and it will work with your QK-A026. Failing that any GPS antenna will do just bear in mind the connector for it is SMA connector.
I hope this helps
Best regards
