if (Serial.read() == 0x7E) { // 7E is the start byte
for (int i = 1; i<20; i++) { // Skip ahead to the analog data
byte discardByte = Serial.read();
int analogMSB = Serial.read(); // Read the first analog byte data

I am sorry but I don't understand your question. What do you mean by LDR? Have you looked at the radios product manual or XCTU's API frame generator?
