Ok now i can send data and if i press button then my arduino goes to sleep. If i let the button go then he wakes up. The last piece that now is missing is that i want to send data before he goes to sleep. It seems like the entire sending part is connected together. Is there a simple line that i can put there, so i can send data immediately before it goes to sleep?
if (digitalRead(A5)==LOW) { //if the button is low, then enter sleepmode
//here i want send a data, for example ON=2 that the button was triggered.
Serial.println(F("go to sleep ... "));
Serial.flush();
LowPower.powerDown(SLEEP_FOREVER, ADC_OFF, BOD_OFF); //Sleepmode
Serial.begin(9600);
Serial.println(F("... done sleeping"));
delay(1000);
//Sleepmode end
}

* This example sends a valid LoRaWAN packet with payload "Hello,
* world!", using frequency and encryption settings matching those of
* the The Things Network.
*
* This uses OTAA (Over-the-air activation), where where a DevEUI and
* application key is configured, which are used in an over-the-air
* activation procedure where a DevAddr and session keys are
* assigned/generated for use with all further communication.
*
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
* violated by this sketch when left running for longer)!
* To use this sketch, first register your application and device with
* the things network, to set or generate an AppEUI, DevEUI and AppKey.
* Multiple devices can use the same AppEUI, but each device has its own
* DevEUI and AppKey.
*
* Do not forget to define the radio type correctly in
* arduino-lmic/project_config/lmic_project_config.h or from your BOARDS.txt.

. I installed the library and added this code. After that i changed the values and it gives me back on error if i try to compile: "expected primary-expression before ‘A5’ " . My goal is to make a trigger, which will tell me whether the door is open or not. i posted here also my code. I appreciate your help.
