Log levels

You can filter and prioritize log messages based on their severity, making it easier to identify and address issues that may arise in your Flipper Zero. Starting with the Error log level, each log level adds more messages to be logged. Log messages are printed to the console via UART and can also be printed to the command-line interface (CLI) with the help of the log command.

The following log level options are available:

• Default: Equivalent to the Info log level.
• None: No events are logged.
• Error: Only errors are logged.
• Warning: Errors and warnings are logged.
• Info: Errors, warnings, and info messages are logged.
• Debug: Errors, warnings, info and debug messages are logged.
• Trace: Errors, warnings, info and debug messages are logged, as well as tracing information from various subsystems.

<div class="warning flipper-callout">
    <div class="callout-header">As the level of logging increases, the device's stability decreases</div>
     To maintain stability and prevent performance degradation and a slow user interface, we recommend setting the log level only when required, as the device logs more events with each level.
</div>

Debug mode

Enabling Debug mode provides additional debugging functionality in Sub-GHz, 125 kHz RFID, NFC, and Infrared applications, as well as new commands in CLI. For example, you can read low-frequency RFID card's RAW data by going to Main Menu -> 125 kHz RFID -> Extra Actions -> Read RAW RFID data.

Debug mode also provides access to the Single Wire Debug (SWD) interface. If you disable Debug mode on your Flipper Zero, the SWD interface will become unavailable.

<div class="warning flipper-callout">
    <div class="callout-header">The device is less stable in Debug mode</div>
     Enable this mode only when necessary, as the mode disables power-saving features and introduces logging for various functions. Consequently, the device's performance may degrade, leading to a slower user interface and reduced stability.
</div>

Heap Trace

A heap trace is a log of memory allocations and deallocations that occur in your Flipper Zero. The heap trace records information about each allocation, including the size of the block of memory allocated, the address of the block of memory, and the time at which it was allocated. Heap traces are useful for debugging memory-related issues, such as memory leaks. Heap Trace log messages are printed to the console via UART.
