* LoRaWAN
*/
// 1) Requires "MCCI LoRaWAN LMIC library", which will be automatically used with PlatformIO but should be added in "Arduino IDE".
// 2) Region and transceiver type should be specified in:
// * Arduino/libraries/MCCI_LoRaWAN_LMIC_library/project_config/lmic_project_config.h for Arduino IDE
// * platformio.ini for PlatformIO
// See https://github.com/mcci-catena/arduino-lmic#configuration for more information
// 3) It has been tested with "TTGO ESP32 SX1276 LoRa 868" and will only work with an ESP32 + LoRa modem
// 4) In order to use LoRaWAN, a gateway should be close to the co2ampel, and an account, an application and a device should be registered,
// e.g. on https://www.thethingsnetwork.org/docs/applications/
// 5) The corresponding keys should be defined in LORAWAN_DEVICE_EUI, LORAWAN_APPLICATION_EUI and LORAWAN_APPLICATION_KEY
// How often should measurements be sent over LoRaWAN?
# define LORAWAN_SENDING_INTERVAL 300 // [s] This value should not be too low. See https://www.thethingsnetwork.org/docs/lorawan/duty-cycle.html#maximum-duty-cycle
// WARNING: If AMPEL_LORAWAN is enabled, you need to modify the 3 following constants!
// This EUI must be in little-endian format, so least-significant-byte first.
// When copying an EUI from ttnctl output, this means to reverse the bytes.
// Reset the MAC state. Session and pending data transfers will be discarded.
LMIC_reset();
// Join, but don't send anything yet.

}
// Checks if OTAA is connected, or if payload should be sent.
// NOTE: while a transaction is in process (i.e. until the TXcomplete event has been received, no blocking code (e.g. delay loops etc.) are allowed, otherwise the LMIC/OS code might miss the event.
// If this rule is not followed, a typical symptom is that the first send is ok and all following ones end with the 'TX not complete' failure.
