IBM LMIC

• Config file: src/lmic/config.h (Default to EU868)
• Changed frequencies: https://github.com/matthijskooijman/arduino-lmic/issues/238
• Fixed channel: https://github.com/matthijskooijman/arduino-lmic/issues/120
• No DIO support: https://github.com/matthijskooijman/arduino-lmic/pull/34

Changed to 433Mhz

• src/lmic/lorabase.h
• Changes: https://github.com/IoTThinks/EasyLoRaWAN/wiki/ChirpStack-configuration#eu433---more-popular

Can run without DIO1 for board with non-connected DIO1

• DIO0 is connected to board.
• Short connected DIO1 to DIO0
• .dio = {LORA_DIO0, LORA_DIO0, LMIC_UNUSED_PIN}

Confirmed data up

• Set last parameter to 1: https://github.com/matthijskooijman/arduino-lmic/blob/master/examples/ttn-abp/ttn-abp.ino#L142
