# LoRa API
## Include Library
```arduino
#include <LoRa.h>
```
## Setup
### Begin
Initialize the library with the specified frequency.
```arduino
LoRa.begin(frequency);
```
* `frequency` - frequency in Hz (`433E6`, `866E6`, `915E6`)
Returns `1` on success, `0` on failure.
### Set pins
Override the default `NSS`, `NRESET`, and `DIO0` pins used by the library. **Must** be called before `LoRa.begin()`.
```arduino
LoRa.setPins(ss, reset, dio0);
```
* `ss` - new slave select pin to use, defaults to `10`
* `reset` - new reset pin to use, defaults to `9`
* `dio0` - new DIO0 pin to use, defaults to `2`
This call is optional and only needs to be used if you need to change the default pins used.
### Set SPI Frequency
Override the default SPI frequency of 10 MHz used by the library. **Must** be called before `LoRa.begin()`.
```arduino
LoRa.setSPIFrequency(frequency);
```
* `frequency` - new SPI frequency to use, defaults to `10E6`
This call is optional and only needs to be used if you need to change the default SPI frequency used. Some logic level converters cannot support high speeds such as 10 MHz, so a lower SPI frequency can be selected with `LoRa.setSPIFrequency(frequency)`.
### End
Stop the library
```arduino
LoRa.end()
```
## Sending data
### Begin packet
Start the sequence of sending a packet.
```arduino
LoRa.beginPacket();
LoRa.beginPacket(implicitHeader);
```
* `implicitHeader` - (optional) `true` enables implicit header mode, `false` enables explicit header mode (default)
Returns `1` on success, `0` on failure.
### Writing
Write data to the packet. Each packet can contain up to 255 bytes.
```arduino
LoRa.write(byte);
LoRa.write(buffer, length);
```
* `byte` - single byte to write to packet
or
* `buffer` - data to write to packet
* `length` - size of data to write
Returns the number of bytes written.
**Note:** Other Arduino `Print` API's can also be used to write data into the packet
### End packet
End the sequence of sending a packet.
```arduino
LoRa.endPacket()
```
Returns `1` on success, `0` on failure.
## Receiving data
### Parsing packet
Check if a packet has been received.
```arduino
int packetSize = LoRa.parsePacket();
int packetSize = LoRa.parsePacket(size);
```
* `size` - (optional) if `> 0` implicit header mode is enabled with the expected a packet of `size` bytes, default mode is explicit header mode
Returns the packet size in bytes or `0` if no packet was received.
### Continuous receive mode
#### Register callback
Register a callback function for when a packet is received.
```arduino
LoRa.onReceive(onReceive);
void onReceive(int packetSize) {
// ...
}
```
* `onReceive` - function to call when a packet is received.
#### Receive mode
Puts the radio in continuous receive mode.
```arduino
LoRa.receive();
LoRa.receive(int size);
```
* `size` - (optional) if `> 0` implicit header mode is enabled with the expected a packet of `size` bytes, default mode is explicit header mode
The `onReceive` callback will be called when a packet is received.
### Packet RSSI
```arduino
int rssi = LoRa.packetRssi();
```
Returns the RSSI of the received packet.
### Packet SNR
```arduino
float snr = LoRa.packetSnr();
```
Returns the estimated SNR of the received packet in dB.
### Available
```arduino
int availableBytes = LoRa.available()
```
Returns number of bytes available for reading.
### Peeking
Peek at the next byte in the packet.
```arduino
byte b = LoRa.peek();
```
Returns the next byte in the packet or `-1` if no bytes are available.
### Reading
Read the next byte from the packet.
```arduino
byte b = LoRa.read();
```
Returns the next byte in the packet or `-1` if no bytes are available.
**Note:** Other Arduino [`Stream` API's](https://www.arduino.cc/en/Reference/Stream) can also be used to read data from the packet
## Other radio modes
### Idle mode
Put the radio in idle (standby) mode.
```arduino
LoRa.idle();
```
### Sleep mode
Put the radio in sleep mode.
```arduino
LoRa.sleep();
```
## Radio parameters
### TX Power
Change the TX power of the radio.
```arduino
LoRa.setTxPower(txPower);
LoRa.setTxPower(txPower, outputPin);
```
* `txPower` - TX power in dB, defaults to `17`
* `outputPin` - (optional) PA output pin, supported values are `PA_OUTPUT_RFO_PIN` and `PA_OUTPUT_PA_BOOST_PIN`, defaults to `PA_OUTPUT_PA_BOOST_PIN`.
Supported values are between `2` and `17` for `PA_OUTPUT_PA_BOOST_PIN`, `0` and `14` for `PA_OUTPUT_RFO_PIN`.
Most modules have the PA output pin connected to PA BOOST,
### Frequency
Change the frequency of the radio.
```arduino
LoRa.setFrequency(frequency);
```
* `frequency` - frequency in Hz (`433E6`, `866E6`, `915E6`)
### Spreading Factor
Change the spreading factor of the radio.
```arduino
LoRa.setSpreadingFactor(spreadingFactor);
```
* `spreadingFactor` - spreading factor, defaults to `7`
Supported values are between `6` and `12`. If a spreading factor of `6` is set, implicit header mode must be used to transmit and receive packets.
### Signal Bandwidth
Change the signal bandwidth of the radio.
```arduino
LoRa.setSignalBandwidth(signalBandwidth);
```
* `signalBandwidth` - signal bandwidth in Hz, defaults to `125E3`.
Supported values are `7.8E3`, `10.4E3`, `15.6E3`, `20.8E3`, `31.25E3`, `41.7E3`, `62.5E3`, `125E3`, and `250E3`.
### Coding Rate
Change the coding rate of the radio.
```arduino
LoRa.setCodingRate4(codingRateDenominator);
```
* `codingRateDenominator` - denominator of the coding rate, defaults to `5`
Supported values are between `5` and `8`, these correspond to coding rates of `4/5` and `4/8`. The coding rate numerator is fixed at `4`.
### Preamble Length
Change the preamble length of the radio.
```arduino
LoRa.setPreambleLength(preambleLength);
```
* `preambleLength` - preamble length in symbols, defaults to `8`
Supported values are between `6` and `65535`.
### Sync Word
Change the sync word of the radio.
```arduino
LoRa.setSyncWord(syncWord);
```
* `syncWord` - byte value to use as the sync word, defaults to `0x34`
### CRC
Enable or disable CRC usage, by default a CRC is not used.
```arduino
LoRa.crc();
LoRa.noCrc();
```
## Other functions
### Random
Generate a random byte, based on the Wideband RSSI measurement.
```
byte b = LoRa.random();
```
Returns random byte.

/*
WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will print the IP address of your WiFi Shield (once connected)
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 5.
If the IP address of your shield is yourAddress:
http://yourAddress/H turns the LED on
http://yourAddress/L turns it off
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
Circuit:
* WiFi shield attached
* LED attached to pin 5
created for arduino 25 Nov 2012

ported for sparkfun esp32

/*
* Udp.cpp: Library to send/receive UDP packets.
*
* NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
* 1) UDP does not guarantee the order in which assembled UDP packets are received. This
* might not happen often in practice, but in larger network topologies, a UDP
* packet can be received out of sequence.
* 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
* aware of it. Again, this may not be a concern in practice on small local networks.
* For more information, see http://www.cafeaulait.org/course/week12/35.html
