ble

Popular

Scan, connect, and communicate with Bluetooth Low Energy devices and beacons.

Version BLE 4.0-5.3

Range Up to 100m

Mode Central & Peripheral

Power Ultra-low (μW)

Configuration

{cfg.key} string "scan" | "connect" | "advertise"

{cfg.key} string MAC address or UUID

{cfg.key} string GATT service UUID

{cfg.key} string Characteristic UUID

Output Example

{node.details.output}

Use scan mode with filters to reduce CPU load. BLE advertising interval affects discovery time.

zigbee

Popular

Create and manage Zigbee mesh networks for smart home and industrial IoT applications.

Standard Zigbee 3.0

Frequency 2.4GHz

Devices 65,000+ per network

Mesh Self-healing

Configuration

{cfg.key} string USB dongle port (e.g., /dev/ttyACM0)

{cfg.key} string Network PAN ID

{cfg.key} number Zigbee channel (11-26)

{cfg.key} boolean Allow new devices to join

Output Example

{node.details.output}

Use a dedicated Zigbee coordinator (CC2531, ConBee II). Channel 25 avoids most Wi-Fi interference.

z-wave

Connect to Z-Wave smart home devices for lighting, locks, sensors, and thermostats.

Standard Z-Wave Plus V2

Frequency 908MHz (US)

Range Up to 100m

Devices 232 per network

Configuration

{cfg.key} string USB controller port

{cfg.key} string Network home ID

{cfg.key} number Device node ID

{cfg.key} string Z-Wave command class

Output Example

{node.details.output}

Sub-GHz frequency provides better range and wall penetration than Wi-Fi or Zigbee.

lora

Popular

Send and receive LoRa packets for ultra-long-range, low-power IoT communication.

Range Up to 15km

Frequency 868/915MHz

Data Rate 0.3-50 kbps

Power Years on battery

Configuration

{cfg.key} string SPI device (e.g., /dev/spidev0.0)

{cfg.key} number Carrier frequency in MHz

{cfg.key} number SF7-SF12 (range vs speed)

{cfg.key} number Signal bandwidth in kHz

Output Example

{node.details.output}

Higher spreading factor = longer range but slower. SF7 for nearby devices, SF12 for maximum range.

rf433

Send and receive 433MHz RF signals for remote controls, weather stations, and simple sensors.

Frequency 433.92MHz

Range Up to 200m

Protocol ASK/OOK

Direction TX & RX

Configuration

{cfg.key} number GPIO pin for TX or RX

{cfg.key} number Protocol number (1-12)

{cfg.key} number Pulse length in μs

{cfg.key} string "transmit" | "receive"

Output Example

{node.details.output}

Add a 17.3cm wire antenna to the module for dramatically improved range. Keep antenna straight and vertical.

nrf24

High-speed short-range communication using NRF24L01+ 2.4GHz radio modules.

Frequency 2.4GHz ISM

Speed 250kbps-2Mbps

Range Up to 1km (PA+LNA)

Pipes 6 simultaneous

Configuration

{cfg.key} number Chip Enable GPIO pin

{cfg.key} number RF channel (0-125)

{cfg.key} string "250kbps" | "1mbps" | "2mbps"

{cfg.key} string Pipe address (5 bytes hex)

Output Example

{node.details.output}

Use PA+LNA modules for extended range. Keep channel away from Wi-Fi (channels 76+ recommended).

rfid

Read and write RFID tags using MFRC522 and compatible readers for access control and tracking.

Frequency 13.56MHz

Reader MFRC522 / PN532

Tags MIFARE 1K/4K

Range Up to 5cm

Configuration

{cfg.key} string "mfrc522" | "pn532"

{cfg.key} string "spi" | "i2c"

{cfg.key} string "read" | "write" | "detect"

{cfg.key} number Memory sector (0-15)

Output Example

{node.details.output}

MFRC522 uses SPI (faster), PN532 supports I2C and UART. Keep default keys for development only.

nfc

Near-field communication for tap-to-pair, data exchange, and contactless card emulation.

Frequency 13.56MHz

Range < 10cm

Modes Read / Write / P2P

Standards NFC-A/B/F/V

Configuration

{cfg.key} string NFC reader device path

{cfg.key} string "reader" | "emulator" | "p2p"

{cfg.key} string "ndef" | "raw"

{cfg.key} number Detection timeout in ms

Output Example

{node.details.output}

NDEF format is universal across NFC devices. Use P2P mode for device-to-device data transfer.

ir

Send and receive infrared signals for remote control of TVs, AC units, and other appliances.

Frequency 38kHz carrier

Protocols NEC, RC5, Sony

Direction TX & RX
