No Problem, but remember, i write it only for first test and used much from Arduino-lmic example, so very dirty.
And i only use a single channel gateway, so if you use a full GW, you must uncomment the block with “LMIC_setupChannel” and delete my definitions!
Good luck & if you have any questions, contact me!

This example sends a valid LoRaWAN packet with payload "Hello,
world!", using frequency and encryption settings matching those of
the The Things Network.
This uses ABP (Activation-by-personalisation), where a DevAddr and
Session keys are preconfigured (unlike OTAA, where a DevEUI and
application key is configured, while the DevAddr and session keys are
assigned/generated in the over-the-air-activation procedure).
Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
violated by this sketch when left running for longer)!
To use this sketch, first register your application and device with
the things network, to set or generate a DevAddr, NwkSKey and
AppSKey. Each device should have their own unique values for these
fields.
Do not forget to define the radio type correctly in config.h.
