Transplanted from Semtech LoRaWAN(https://github.com/Lora-net/LoRaMac-node) protocol to "ESP32 + Arduino" platform. Use RTC, support deep sleep, only working with ESP32 + LoRa boards made by HelTec Automation(TM). Need a unique license to use it.

Good afternoon
Dear Aaron Lee HelTec Automation
Henry Espinoza greets you, from GYE ECU.
I saw your page and I think you can help me with a student project on the subject of microcontrollers that I am carrying out.
It consists of a Network of 4 wireless sensors via LoRa for gas monitoring using MQ136 sensors.
I have:
4 HELTEC modules (WIFI LoRa 32) 868Mhz 4 MQ136 sensors (SainSmart MQ136 Semiconductor Sensor for Hydrogen Sulfide) 1 HELTEC HT-M01 Mini LoRa Gateway Module
I need help with the codes and steps to follow to achieve this: how to connect the sensors to each node HELTEC (WIFI LoRa 32) 868Mhz (pins)?
How to display the gas concentration on the OLED?
How to send the data of the 4 nodes to the HELTEC HT-M01 Mini LoRa Gateway?
How to configure the LoRaWAN network (LoRaServer in ChirpStack)?
Grateful for your help. Heltec products with great will keep learning and promoting the brand in Ecuador.
