=TTN Node= [[File:TTN Node IoT.jpg|400px]] Build your own TTN Node / IoT Sensor in one afternoon. Some soldering and programming required. This TTN Node exist of the folowing components (Cost € 25,=) : * Arduino nano (clone) * Microchip [http://www.microchip.com/wwwproducts/en/RN2483 RN2483] * [https://github.com/jpmeijers/TTNEnschedeMote Print] * Battery * USB kabel If you join this workshop you get all of the above parts to make the Node. You are also welcome if you have your own parts and want a own TTN design, we can then exchange experience and tips. Join this workshop [http://goo.gl/forms/M1KB6aq2qd here]. =Instructions= ===Test Arduino Nano - Program blink, change frequency, blink.=== *Software serial on pins 10, 11. Add wire for loopback. ===Solder RN2483 - Press down with finger at correct location. Tin on corners. === * Solder rest of pins: 6, 7, 32, 33, 34 - the others are not neccesary * http://forum.thethingsnetwork.org/t/how-to-build-your-first-ttn-node-arduino-rn2483/1574 ===Break header strip into two peices of 15 pins.=== * Use spreader to hold right angle header strips in place. * Solder first and last pin of header strips.* * Remove spacer, solder rest of header pins. ===Press Arduino Nano down on soldered header strips. === * If everything looks correct, solder the Arduino to the header pins. ===TTNCTL=== * Download and follow the steps at https://staging.thethingsnetwork.org/wiki/Backend/ttnctl/QuickStart * When registering a device, following the procedure for registering a personalized device (ABP). * Add the parameter --relax-fcnt * Choose a random device address: https://www.random.org/bytes/ - 4 bytes, capital letters. * Now ttnctl subscribe --plain to wait for packets. ===Arduino code - https://github.com/jpmeijers/ttnmapperarduino === * Download the zip file and place the library and example files in your Arduino folder. * Open TXfastViaTTN.ino * Change line 74 to your own AppEUI, NwkSKey, AppSKey and DevAddr * Program the code to the Arduino. * If everything is correct you should see packets arriving in ttnctl. ===Optional=== *Install the TTNmapper Android app and help us map the coverage of the network. *Read the internal temperature sensor of the Arduino and transmit the value over TTN. *Add an external prototyping board, add sensors, transmit the values.
