+A custom Decoder Function translates the payload bytes into a set of JSON values required by the Integrations for both Mapper and Cargo.
+This turns the Base64 Payload into values for Lat, Long, Altitude, Speed, Battery, and Sats.
 
-Note that HDOP is not sent in this data.
+The [Decoder Function](https://github.com/Max-Plastix/tbeam-helium-mapper/blob/main/console-decoders/unified_decoder.js) can be pasted directly into the Console custom function.

 # Downlink
 This builds adds the option to reconfigure the Mapper remotely via Helium Downlink (network to device).  You can change the maximum Time Interval, Distance, and Battery Cut-off voltage remotely.
