Sigfox modul stopped working

[fronak]

Hello,
I had SmartEverything board for just 3 days and today sigfox module suddenly stopped sending messages (it was in the middle of the day I had it in my car and find it out tonight). I tried to use read firmware example but it doesn't return anything. Is there a way to find out if modem is completely dead? If so, I would use my warranty with RSComponents.

First try the internal UART comunication to understand if the chip still answer to any comand.

For Example use the ReadSwVersion (U should be able to see the FW string from the USB serial).

Or the SendDataEU example (U should see the OK message in console or the Green led ligth on)
