Hi,
I want to transmit two integer values of an analog poti 0-1023.
What's the smartest way to transmit this and how to seperate them again at the receiving side?
Unfortunately I didnt find any example how to handle it
// rf95_reliable_datagram_client.pde
// -*- mode: C++ -*-
// Example sketch showing how to create a simple addressed, reliable messaging client
// with the RHReliableDatagram class, using the RH_RF95 driver to control a RF95 radio.
// It is designed to work with the other example rf95_reliable_datagram_server
// Tested with Anarduino MiniWirelessLoRa, Rocket Scream Mini Ultra Pro with the RFM95W
#include <RHReliableDatagram.h>
#include <RH_RF95.h>
#include <SPI.h>
#define CLIENT_ADDRESS 1
#define SERVER_ADDRESS 2
// Singleton instance of the radio driver
RH_RF95 driver;
//RH_RF95 rf95(5, 2); // Rocket Scream Mini Ultra Pro with the RFM95W
// Class to manage message delivery and receipt, using the driver declared above
RHReliableDatagram manager(driver, CLIENT_ADDRESS);
// Need this on Arduino Zero with SerialUSB port (eg RocketScream Mini Ultra Pro)
//#define Serial SerialUSB
void setup()
{
// Rocket Scream Mini Ultra Pro with the RFM95W only:
// Ensure serial flash is not interfering with radio communication on SPI bus
// pinMode(4, OUTPUT);
// digitalWrite(4, HIGH);
Serial.begin(9600);
while (!Serial) ; // Wait for serial port to be available
if (!manager.init())
Serial.println("init failed");
// Defaults after init are 434.0MHz, 13dBm, Bw = 125 kHz, Cr = 4/5, Sf = 128chips/symbol, CRC on
// The default transmitter power is 13dBm, using PA_BOOST.
// If you are using RFM95/96/97/98 modules which uses the PA_BOOST transmitter pin, then
// you can set transmitter powers from 5 to 23 dBm:
// driver.setTxPower(23, false);
// If you are using Modtronix inAir4 or inAir9,or any other module which uses the
// transmitter RFO pins and not the PA_BOOST pins
// then you can configure the power transmitter power for -1 to 14 dBm and with useRFO true.
// Failure to do that will result in extremely low transmit powers.
// driver.setTxPower(14, true);
}
uint8_t data[] = "Hello World!";
// Dont put this on the stack:
uint8_t buf[RH_RF95_MAX_MESSAGE_LEN];
void loop()
{
Serial.println("Sending to rf95_reliable_datagram_server");
// Send a message to manager_server
if (manager.sendtoWait(data, sizeof(data), SERVER_ADDRESS))
{
// Now wait for a reply from the server
uint8_t len = sizeof(buf);
uint8_t from;
if (manager.recvfromAckTimeout(buf, &len, 2000, &from))
{
Serial.print("got reply from : 0x");
Serial.print(from, HEX);
Serial.print(": ");
Serial.println((char*)buf);
}
else
{
Serial.println("No reply, is rf95_reliable_datagram_server running?");
}
}
else
Serial.println("sendtoWait failed");
delay(500);
