getValue(source)¶

Returns the value of a source.

The list of fixed sources:

In OpenTX 2.1.x the telemetry sources no longer have a predefined name. To get a telemetry value simply use it's sensor name. For example:

• Altitude sensor has a name "Alt"
• to get the current altitude use the source "Alt"
• to get the minimum altitude use the source "Alt-", to get the maximum use "Alt+"

@status current Introduced in 2.0.0, changed in 2.1.0, Cels+ and Cels- added in 2.1.9

Parameters¶

• source can be an identifier (number) (which was obtained by the getFieldInfo())

or a name (string) of the source.

Return value¶

• value current source value (number). Zero is returned for:
• non-existing sources
• for all telemetry source when the telemetry stream is not received
• far all non allowed sensors while FAI MODE is active
• table GPS position is returned in a table:
• lat (number) latitude, positive is North
• lon (number) longitude, positive is East
• pilot-lat (number) pilot latitude, positive is North
• pilot-lon (number) pilot longitude, positive is East
• table GPS date/time, see getDateTime()
• table Cells are returned in a table (except where no cells were detected in which case the returned value is 0):
• table has one item for each detected cell:
• key (number) cell number (1 to number of cells)
• value (number) current cell voltage

Notice¶

Getting a value by its numerical identifier is faster then by its name. While Cels sensor returns current values of all cells in a table, a Cels+ or Cels- will return a single value - the maximum or minimum Cels value.
