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 EdgeTX 2.4.0


This example also runs in OpenTX versions where the function returned only one value:
local function run(event)
local ver, radio, maj, minor, rev, osname = getVersion()
print("version: "..ver)
if radio then print ("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
return { run=run }
Output of the above script in simulator:
version: 2.4.0
radio: tx16s-simu
maj: 2
minor: 4
rev: 0
osname: EdgeTX
