The Things Uno SDK

Looks nice and easy this way.
1. I miss the "mac get status" call. I use that allways before a transmit to check if the devices is ready.
2. From the example, ttu.sendString() returns true or false , not the results you really need, for instance "Rejoin needed"
You could put the return message in a status field, or handle the session control automagicaly and build that into the class
3. also "mac get deveui" could be very usefull, since you need it for OTAA
