RadioHead

RadioHead: packet radio software library for microprocessors: http://www.airspayce.com/mikem/arduino/RadioHead/

Library organization

RadioHead uses driver classes and manager classes.

• Driver classes are low-level interfaces to different kinds of packet radios and packetized message protocols
• Manager classes are high-level interfaces for sending and receiving messages

Each RadioHead program must create an instance of a Driver (to access the radio), and a Manager (to send and receive messages, using the driver, from the application). The Driver and Manager must be instantiated, and the Manager must be initialized. Then the Manager can be used.

• RH_RF22 Works with Hope-RF RF22B and RF23B based transceivers, and compatible chips and modules, including the RFM22B transceiver module such as this bare module: http://www.sparkfun.com/products/10153 and this shield: http://www.sparkfun.com/products/11018 and this board: http://www.anarduino.com/miniwireless and RF23BP modules such as: http://www.anarduino.com/details.jsp?pid=130 Supports GFSK, FSK and OOK. Access to other chip features such as on-chip temperature measurement, analog-digital converter, transmitter power control etc is also provided.

• RH_RF24 Works with Silicon Labs Si4460/4461/4463/4464 family of transceivers chip, and the equivalent HopeRF RF24/26/27 family of chips and the HopeRF RFM24W/26W/27W modules. Supports GFSK, FSK and OOK. Access to other chip features such as on-chip temperature measurement, analog-digital converter, transmitter power control etc is also provided.

• RH_RF69 Works with Hope-RF RF69B based radio modules, such as the RFM69 module, (as used on the excellent Moteino and Moteino-USB boards from LowPowerLab http://lowpowerlab.com/moteino/ ) and compatible chips and modules such as RFM69W, RFM69HW, RFM69CW, RFM69HCW (Semtech SX1231, SX1231H). Also works with Anarduino MiniWireless -CW and -HW boards http://www.anarduino.com/miniwireless/ including the marvellous high powered MinWireless-HW (with 20dBm output for excellent range). Supports GFSK, FSK.

• RH_NRF24 Works with Nordic nRF24 based 2.4GHz radio modules, such as nRF24L01 and others. Also works with Hope-RF RFM73 and compatible devices (such as BK2423). nRF24L01 and RFM73 can interoperate with each other.

• RH_NRF905 Works with Nordic nRF905 based 433/868/915 MHz radio modules.

• RH_NRF51 Works with Nordic nRF51 compatible 2.4 GHz SoC/devices such as the nRF51822. Also works with Sparkfun nRF52832 breakout board, with Arduino 1.6.13 and Sparkfun nRF52 boards manager 0.2.3

• RH_RF95 Works with Semtech SX1276/77/78/79, Modtronix inAir4 and inAir9, and HopeRF RFM95/96/97/98 and other similar LoRa capable radios. Supports Long Range (LoRa) with spread spectrum frequency hopping, large payloads etc. FSK/GFSK/OOK modes are not (yet) supported.

• RH_MRF89 Works with Microchip MRF89XA and compatible transceivers. and modules such as MRF89XAM9A.

• RH_CC110 Works with Texas Instruments CC110L transceivers and compatible modules such as Anaren AIR BoosterPack 430BOOST-CC110L

• RH_ASK Works with a range of inexpensive ASK (amplitude shift keying) RF transceivers such as RX-B1 (also known as ST-RX04-ASK) receiver; TX-C1 transmitter and DR3100 transceiver; FS1000A/XY-MK-5V transceiver; HopeRF RFM83C / RFM85. Supports ASK (OOK).

• RH_Serial Works with RS232, RS422, RS485, RS488 and other point-to-point and multidropped serial connections, or with TTL serial UARTs such as those on Arduino and many other processors, or with data radios with a serial port interface. RH_Serial provides packetization and error detection over any hardware or virtual serial connection. Also builds and runs on Linux and OSX.

• RH_TCP For use with simulated sketches compiled and running on Linux. Works with tools/etherSimulator.pl to pass messages between simulated sketches, allowing testing of Manager classes on Linux and without need for real radios or other transport hardware.
