RADAR_BAUDRATE

#define RADAR_BAUDRATE   256000

Definition at line 27 of file changeConfig.ino.

RADAR_RX_PIN

#define RADAR_RX_PIN   16

Example: Change configuration of the LD2410.

This sketch shows how to:

1. Initialize the radar on Serial1.
2. Query all current configuration values from the sensor.
3. Clone the config into a local variable.
4. Modify some settings (timeout, sensitivities).
5. Write the modified config back to the sensor.

Warning

Important: Make sure to adjust RADAR_RX_PIN and ADAR_TX_PIN to match you actual wiring.

RADAR_TX_PIN

#define RADAR_TX_PIN   17

Function Documentation

loop()

void loop

(

)

Arduino loop function which does nothing.

The LD2410Async library runs a FreeRTOS background task that automatically handles all jobs that are related to the radar sensor. Therefore the main loop doesnt have to da any LD2410 related work and is free for anything else you might want to do.

Definition at line 148 of file changeConfig.ino.

onConfigApplied()

void onConfigApplied	(	LD2410Async *	sender,
		LD2410Async::AsyncCommandResult	result )

Callback after the new config has been written to the sensor.

This method just checks and prints the result

Definition at line 47 of file changeConfig.ino.

onConfigReceived()

void onConfigReceived	(	LD2410Async *	sender,
		LD2410Async::AsyncCommandResult	result )

Callback after receiving the config data.

Checks the result of the async requestAllConfigSettingsAsync() command, gets a clone of the config data using getConfigData(), modifies it and writes back using the async configureAllConfigSettingsAsync() command.

Note

Always check the result of the async command that has triggered the callback. Otherweise async commands can fail, timeout or get canceled without you relizing it. In callback methods is is generally advised to access members of the LD2410Async instance via the sender pointer. This ensures that you are allways working with the correct instance, which is important if you have multiple LD2410Async instances. Also keep in mind that callbacks should be as short and efficient as possible to avoid blocking the background task of the library.

RadarSerial()

HardwareSerial RadarSerial

(

1

)

Create a HardwareSerial instance (ESP32 has multiple UARTs) bound to UART1

setup()

void setup

(

)

Arduino setup function which initializes the radar and starts the config change process.

begin() starts the background task of the LD2410Async library which automatically handles incoming data and triggers callbacks. The onDetectionDataReceived callback is registered to receive detection data. requestAllConfigSettingsAsync() will fetch all config data from the sensor and triggers the onConfigReceived callback when done.
