Returns the value of a source.
The list of valid sources is available:
for OpenTX 2.0.x at
for OpenTX 2.1.x at (depreciated)
for OpenTX 2.1.x Taranis and Taranis Plus at
for OpenTX 2.1.x Taranis X9E at
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
source can be an identifier (number) (which was obtained by the getFieldInfo())
or a name (string) of the source.
value current source value (number). Zero is returned for:
non-existing sources
for all telemetry source when the telemetry stream is not received
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
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.
