TTGO LoRa ESP32 OLED - Error when compiling

Development Tools Cloud IoT
6

Does my architecture seem to be correct ?

  1. I want to use a LORA Network delivered by Orange (public gateways)
  2. I have therefore ordered TTGO LOra ESP32 Lora device
  3. I create in the Arduino IoT Cloud a device LoraWan
  4. I have created a simple THING and I associate the Lora device with EUI and APP keys
  5. Then I try to compile a "standard" sketch "automatically" created by Arduino IoT CLoud

Does it seems to be OK ?
When I will be able to compile and download the sketch on the board I will create an Object in the Orange Live Object portal.
