Check if the TFT update process is currently running.
This method provides a way to determine if the Nextion display is in the process of updating its TFT firmware. When a TFT update is in progress, certain operations or commands may be restricted or could interfere with the update process. By checking the state of the update process, the system can make informed decisions about performing actions that involve communication with the Nextion display.

Retrieves the number of commands pending in the Nextion command queue.
This function returns the current count of commands that have been queued but not yet processed for the Nextion display. The Nextion command queue is used to store commands that are sent to the Nextion display for various operations like updating the display, changing interface elements, or other interactive features. A larger queue size might indicate a higher processing time or potential delays in command execution. This function is useful for monitoring the command flow and managing the execution efficiency of the Nextion display interface.

bool esphome::nextion::Nextion::set_protocol_reparse_mode | ( | bool | active_mode | ) |
Sets the Nextion display's protocol reparse mode.
This function toggles the Nextion display's protocol reparse mode between active and passive. In active mode, the display actively parses incoming data. In passive mode, it does not parse data unless specifically instructed to do so. This is useful for managing how the Nextion display interprets incoming commands, especially during initialization or in scenarios where precise control over command processing is needed.
active_mode | A boolean value indicating the desired reparse mode.

Sets whether the Nextion display should skip the connection handshake process.
skip_handshake | True or false. When skip_connection_handshake is true, the connection will be established without performing the handshake. This can be useful when using Nextion Simulator. |
Example:
When set to true, the display will be marked as connected without performing a handshake.
void esphome::nextion::Nextion::set_start_up_page | ( | uint8_t | page_id = 255 | ) |
Sets which page Nextion loads when connecting to ESPHome.
page_id | The page id, from 0 to the lage page in Nextion. Set 255 (not set to any existing page) to wakes up to current page. |
Example:
The display will go to page 2 when it establishes a connection to ESPHome.

bool esphome::nextion::Nextion::upload_tft | ( | uint32_t | baud_rate = 0 , |
bool | exit_reparse = true |
||
) |
Uploads the TFT file to the Nextion display.
This function initiates the upload of a TFT file to the Nextion display. Users can specify a target baud rate for the transfer. If the provided baud rate is not supported by Nextion, the function defaults to using the current baud rate set for the display. If no baud rate is specified (or if 0 is passed), the current baud rate is used.
Supported baud rates are: 2400, 4800, 9600, 19200, 31250, 38400, 57600, 115200, 230400, 250000, 256000, 512000 and 921600. Selecting a baud rate supported by both the Nextion display and the host hardware is essential for ensuring a successful upload process.
baud_rate | The desired baud rate for the TFT file transfer, specified as an unsigned 32-bit integer. If the specified baud rate is not supported, or if 0 is passed, the function will use the current baud rate. The default value is 0, which implies using the current baud rate. |
exit_reparse | If true, the function exits reparse mode before uploading the TFT file. This parameter defaults to true, ensuring that the display is ready to receive and apply the new TFT file without needing to manually reset or reconfigure. Exiting reparse mode is recommended for most upload scenarios to ensure the display properly processes the uploaded file command. |
