Debug
The Console Debug tool allows you to quickly and easily examine device messages. This enables you to verify and debug issues much more easily without requiring the data to be sent to an application endpoint first. For security and privacy reasons the Debug tool does not persist data. Instead, the 40 most recent events are accumulated from the time the Debug window is opened.
Using The Debug Tool
The Debug tool is located on the upper right side of every device page (shown in the image below). To access it, just click the Debug tab and a window will pop out.
At first you will see a spinning wheel and the message waiting for data. This is because the Debug tool only shows packets that come through while the window is open.
Once packets are received or sent down to your device, you will see them display immediately in the Debug window, seen here:
Debug Packet Types
The Debug tool will display a message for every uplink or downlink. For detailed information on the contents of the messages please see the JSON schema documentation.
:::info[Payloads shown in the debug messages are [base64]
encoded](https://en.wikipedia.org/wiki/Base64), as are the JSON messages received by integrations. You will need to decode the payload strings in order to correctly interpret the payload data. One way to do this is to use a Function Decoder.
:::
Activation
When your device first joins the network, you will see a special uplink message just for the activation, which will not have a payload, as shown below, and only includes a single hotspot.

Uplink
For uplink packets, a message similar to the one below will be shown. In addition to the original
uplink message data, which starts at the very bottom, these packet types will also show a message
for each integration attached to the device, so that you can examine what is being sent to those
endpoints. For the message shown below, you can see there is a message for a RequestBin and
Cayenne Integrations attached to this device. You can differentiate uplink messages by keeping
track of the frame_up count.

Downlink / ACK
Downlink and ACK messages will only show a single hotspot, similar to the activation message.
You can differentiate downlink messages by keeping track of the frame_down count.
