# getVersion()

Return OpenTX version

@status current Introduced in 2.0.0, expanded in 2.1.7, radio type strings changed in 2.2.0, OS name added in 2.3.14

### Example

This example also runs in OpenTX versions where the function returned only one value:

```lua
local function run(event)
  local ver, radio, maj, minor, rev, osname = getVersion()
  print("version: "..ver)
  if radio then print ("radio: "..radio) end
  if maj then print ("maj: "..maj) end
  if minor then print ("minor: "..minor) end
  if rev then print ("rev: "..rev) end
  if osname then print ("osname: "..osname) end
  return 1
end

return {  run=run }
```

Output of the above script in simulator:

```
version: 2.3.14
radio: taranis-simu
maj: 2
minor: 3
rev: 14
osname: OpenTX
```
