The LoRa Protocol

Good evening,
I have a problem with the LoRa protocol.
The goal is to read through a DHT11 sensor, connected to a Heltec Wireless Stick card, the temperature and then send the temperature data to a second card using the LoRa protocol.
Communication is not done, could someone help me?
