Continuing the discussion from How to Transmit/Receive Multiple Data with RA-02 LoRa SOLVED:

Please let us know the library.

for RA-02 LoRa point to point communications probably used the Arduino LoRa library

if you look at File>Examples>LoRa you will find code for a simple LoRaReceiver and LoRaSender which are a good start

for a more complex example have a look at need-advice-on-a-home-project which transmits/receives a structure

Edit: what host microcontroller are you thinking of using?
the RA-02 uses 3.3V logic therefore use a microcontroller which uses 3.3V logic, e.g. ESP32, RP2040, 3.3V pro micro, 3.3V pro mini, etc

I am using below line to send array.

void send_data() {
  LoRa.beginPacket();
  for (int i = 0; i < n; i++) {
    LoRa.write(A[i]);
  }
  LoRa.endPacket();
}

which library are you using?

LoRa.h

what array type do you wish to transmit? e.g. byte, int, float, ?
all the array or just part of it?
in general you use

virtual size_t write(const uint8_t *buffer, size_t size);

where size is a byte count

My entire data is in byte. I am reading certain buttons and pots making array and transmitting.

Thanks.
