Hey guys,

I’ve spent some time trying to get the Container demo loaded on my Mangoh Red and the first step in the ReadMe says "Modify ‘mangOH/tergetDefs.mangoh’ to set `export SDEF_TO_USE = $(MANGOH_ROOT)/samples/Demos/containerTracking.sdef`

I have navigated to the file in $LEGATO\_ROOT/targetDefs and tried adding the export line to the beginning of the file and also to the end with no avail.

I run ‘make wp85’ from the legato folder. I have also tried running ‘make wp85’ from the $MANGOH\_ROOT/samples/Demos folder, but would expect some problems there since there are a whole bunch of .sdef files. How do I specify the SDEF file to use?

Sorry if this is an entry-level question!

Brandon

Hi Brandon,

You will need to get the WiFi/BT IoT card ( [https://www.digikey.com/products/en?keywords=1788-1008](https://www.digikey.com/products/en?keywords=1788-1008)) to get this going.  
#2: Look through the containerTracking.sdef, what you really need are the following files. You can add them to your own sdef:  
$MANGOH\_ROOT/apps/MqttClient/mqttClient  
$MANGOH\_ROOT/apps/DataRouter/dataRouter

```
// Command-line tools.
$LEGATO_ROOT/apps/tools/tools

$MANGOH_ROOT/samples/Demos/BluetoothUtil/bluetoothUtil
$MANGOH_ROOT/samples/Demos/BleSensorInterface/bleSensorInterface

```

#3: Add the driver for the bluetooth device. check the tutorials on the mangoh page.
