Hello everyone!
I have un problem since two weeks and I d’ont find solution. Help me please 
.
I have this configuration:
- Arduino Uno with Dragino Shield v1.4 for EU 868 Mhz.
- Dragino Lora Gateway LG01-P
The connection between Dragino gateway and Dragino Shiel is Ok on TTN but I can’t receive data on end device.
My gateway configuration :
My Gateway configuration on TTN with data from my device
My dragino shield code :

*H - This example sends a valid LoRaWAN packet with payload "Hello,
- world!", using frequency and encryption settings matching those of
- the (early prototype version of) The Things Network.
- Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in g1,
- 0.1% in g2).
- Change DEVADDR to a unique address!
- See http://thethingsnetwork.org/wiki/AddressSpace
- Do not forget to define the radio type correctly in config.h.
- Required Library:
- Require Hardware:
-
- LoRa Shield + Arduino
-
- LoRa GPS Shield + Arduino
-
- LoRa Mini etc.
