It is the default option when you create the shipment and it’s called “Any”.
The version is parsed from the binary file you upload during the shipment creation.
Every Blynk.Edgent firmware has 2 versions:
- Firmware version - in edgent it’s defined by BLYNK_FIRMWARE_VERSION (“fw”)
- Generic version - in edgent it’s defined by BLYNK_VERSION (“ver”)
When hardware connects to the server it’s always sends both these versions.
So server always knows what version this device has.
You should leave that field empty. It used for debugging purposes.
