I followed the back instructions. Nothing happens,tried pressing boot,en,switching on and off and everything. Mine is out of function.

Maybe you should contact the customer service.

just received,but how can i use it?

The back cover has operating instructions; just follow the steps to power on and start the device,and that's it. There's nothing else that requires additional operation.

Does this device alone block bluetooth? Or does it block Wifi or both?

Its main feature is Bluetooth interference,and the Bluetooth uses several channels of 2.4G,or more precisely,the 2.4G frequency band. The Wi-Fi is a dual-band 2.4G 5G frequency band.

How do I use this? Only mode one lightens up,and pressing the other button activates nothing,doesnt seem to work.

What distance does it reach?

It supports blocking Wi-Fi,but the distance cannot be tested as it is greatly affected by the environment.

After connecting the Type-C to a 5V power supply, press the switch button on the adapter board from OFF to ON; simultaneously, press the RST reset button on the ESP32 development board; it is now ready for use; Note: This product is only for learning purposes. Please abide by local laws and regulations.

Specifications:

Product: ESP32 DevKitC + NRF24L01 PA LNA 2.4GHz Module Development Board

Frequency: 2.4GHz

Module support: Bluetooth blocker signal and Wifi support

Power supply: Type-C to 5V power supply

Switch operation: Press the switch button on the adapter board from OFF to ON

Reset operation: Press the RST reset button on the ESP32 development board

Intended use: Solely for learning purposes

Please note that you must ensure the 8-pin connector is aligned before inserting it to turn on power. Otherwise, a short circuit may occur. For 2x4 pin connectors, simply align them correctly and insert them.

Operating steps: 1. Turn on the switch. 2. Plug in the power (operating current approximately 5V 0.4A, which can disconnect the communication between the phone and the Bluetooth speaker). 3. After powering on, press the EN button. You can then check if the phone's Bluetooth or the Bluetooth speaker has disconnected. The other button is the boot button. You only need to press the boot button when flashing the firmware; otherwise, it will have no effect. Tips: 1. Pressing and releasing the EN button for two seconds will restart the device. To stop operation, use the switch to turn it off. 2. Pressing the boot button followed by the EN button will also prevent the device from running. Pressing the boot button while plugging in the power may result in firmware loss (i.e., entering flashing mode without flashing firmware, restarting, and powering off may erase the flashed firmware).

Package Included:

1 x ESP32-DevKitC development board

2 x NRF24L01+PA+LNA modules

1 x Accompanying adapter board

2 x Antennas

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
