Goodmorning @adrewetx ,
We are well willing to beta test your product with our LTE100 GlobalSat device. I therefore have opened a research group on your GridLocate GPS tracker website : LTE_Globalsat_tester.
When you give some more info on adding a device on your platform, we will be glad to do some testing, just like we did with EZFinder, that also has a smartphone app by the way.
The accuracy then tested was quite good: max error of 10m. The API endpoint they gave me for the TTN HTTP integration was : http://api1.ezfinder.com.tw/API/ttn.aspx
If you could provide me with some more specs on adding the device registered on TTN (via our public lora provider WirelessThings in Belgium) into the GridLocate dashboard, we look forward to give you our user experience.
Have a nice day.
