Sending an array through and HC-12 module

Hello,
I am rather new to coding Arduinos, and I am trying to create a controller for an RC airplane that I am building (which also uses an Arduino). I am using HC-12 Transceiver modules for communication, and I was wondering what code I have to use to send an array of data through the transceiver.

My basic idea is that I read in the values from 2 joysticks (X,Y, and a button for each), put it into an array, and then send it through to the other HC-12 module. I then want to receive data from the sensors I will be putting on the airplane, which I can then display on my LCD screen.

What would be the best way to send/receive the data through the HC-12? I’m having trouble with the code.

My controller code looks something like this (it’s mainly pseudocode right now):

  /*************************
   * Tasks
  ************************/
  //1. Read in all joystick values
  //2. Arrange joystick values as an array
  //3. Send Joystick Array through HC-12 Module
  //4. Receive Temperature/Pressure from HC-12 module
  //5. Convert Pressure to Altitude
  //6. Display Pressure and Temperature on LCD screen



//Setup for Joysticks
#define LJX A0
#define LJY A1
#define RJX A2
#define RJY A3
#define LJB 2
#define RJB 3



//setup for HC-12 Tranceiver Module
#include <SoftwareSerial.h>

SoftwareSerial HC12(12,13);   //TX and RX pins for the HC-12 Module



//setup for I2C LCD screen
#include <LiquidCrystal_I2C.h>


void setup() {
  // put your setup code here, to run once:

  //joystick setup
  pinMode(LJX,INPUT);
  pinMode(LJY,INPUT);
  pinMode(RJX,INPUT);
  pinMode(RJY,INPUT);
  pinMode(LJB,INPUT_PULLUP);
  pinMode(RJB,INPUT_PULLUP);
  

  //HC-12 Setup
  HC12.begin(9600);
  
}

void loop() {
  // put your main code here, to run repeatedly:





  //1.//
  int LX = analogRead(LJX);
  int LY = analogRead(LJY);
  int RX = analogRead(RJX);
  int RY = analogRead(RJY);
  int LB = digitalRead(LJB);
  int RB = digitalRead(RJB);



  //2.//
  int Joysticks[] = {LX,LY,RX,RY,LB,RB};

  //3.//
  HC12.write(Joysticks);  // does this work for the code or do I need to do something else for it? 
  
  //and more after this. see "tasks" at the beginning for what comes after this.
  
}

There’s no “how to do it” information available, no easy pill to pick up and swallow. One good friend is Google, “Arduino + RC”.

Alright, thanks.

HC12 sounds like a poor choice for remote control of a model aeroplane.

You would need to be sending packets as in information from the joysticks on the transmitter to the servos on the receiver around every 20mS.

Have you tested that the HC12 is fast enough ?

And do appreciate that in a lot of places using an HC12 for practical RC control is likely illegal due to duty cycle restrictions.
