Dragino Arduino Shield 915Mhz TTN Connection Problem

Hello,
just to be on the safe side:
The code and the LMIC library you mentioned in this thread should work with an Arduino Uno and a Dragino GPS/LoRa shield here in Europe? (I would add the GPS code as soons as OTAA is working.)
Thank you, Tore

An Uno is not a very good platform choice, LMiC is fairly heavyweight. Most effort goes into solutions based on various ARM chips (and in many cases, ports of Arduino thereto). Some also use the ESP8266.

You may well be able to make it work on an Uno, but using something like an Adafruit Feather or an ESP8266 as the host would more closely replicate what maintainers tend to test.

The primary place where the Uno was popularly used was with an AT-command set module that implemented the whole LoRaWAN stack in its own built in processor; using an Uno with a bare radio where the LoRaWAN protocol must be implemented on the main MCU is a lot less common, compared to using cheap ARM MCUs with more RAM and flash.
