+# Verbose Output
+
+For advanced work with the firmware, enabling **Verbose Mode** is incredibly helpful. This is especially true for data encoding and transmission. 
+
+When verbose messaging is enabled, verbose messages are prefixed with a **[V]** and Debug messages are prefixed with a **[D]**.
+
+## Enabling verbose Mode
+
+There are three main methods to enable verbose mode:
+
+| Location | Details |
+|--|--|
+|Settings Menu | Settings>Application Settings > Verbose Messages. Enabled/Disable Verbose Messaging. This setting will persist across restarts.|
+!!verbose Console Command| This toggles verbose messages and is not persistent|
+|Start Menu - Select option 'v' | Enables verbose messages before system startup. This value is not persistent|
+
+## Output LoRaWAN Encoding
+
+When verbose messaging is enabled, when a loRaWAN message is packed, the packed values and the overall payload is output. 
+
+The following is an example of output for two data values:
+
+![Data Packing](assets/img/verbose-lora-message.png)
+
+In this example, verbose output is enabled using the console command **!verbose**, and a logging event triggered using **!log-now**. 
+
+Two sensor values are packed for transmission - **Humidity** and **TemperatureF**. The verbose message output includes the Value Type/ID for each data value, as well as the encoded value in hexadecimal. 
+
+And once a LoRaWAN data payload is sent, the entire 11 byte payload is output, along with it's send status and associated frame ID. 
+
+## Device Value Type IDs
+
+For each supported device, a subset of parameters are enabled for LoRaWAN transmission. With verbose output enabled, these parameters are indicated by having a Value Type ID when viewed in on a device settings page. 
+
+The following is an example of the Value Type codes for the BME280 device:
+
+![Parameter Value Types](assets/img/verbose-value-type.png)
+
+On this page, the parameters that have **Value Types** codes are enabled for LoRaWAN transmission. 
+
+> [!NOTE]
+> Parameters that are disabled are not sent to the LoRaWAN.
+
+## Startup Messages
+
+If Verbose Output is enabled and save in the system settings, or if the ***[v]erbose*** startup mode was selected, some addition messages are output during the startup sequence. 
+
+And example of startup messages:
+
+![Startup Output](assets/img/verbose-startup.png)
+
+In this example, "Verbose Output" was enabled in the system settings, and is noted on startup. 
+
+Several **Debug** messages related to some settings not saved/restore - but these can easily be ignored. 
+
+Additional information is output when connected to the LoRaWAN network, including the device EUID, and what operating class the LoRaWAN module is set to.
