 For the devices in the LoRaWAN platform, we will use an Autonomo board with a LoRaBee holding the Microchip RN2483 module. According to [[http://shop.sodaq.com]], Autonomo is a matchbox-sized powerhouse which uses the new Atmel Cortex M0+ 32bit micro controller. One advantage of such device is that it can be powered by a smartphone-sized solar panel. For the devices in the LoRaWAN platform, we will use an Autonomo board with a LoRaBee holding the Microchip RN2483 module.

One advantage of such device is that it can be powered by a smartphone-sized solar panel.
  
-In order to configure the device, you need to install the Arduino IDE from [[https://www.arduino.cc/en/Main/Software]]. Then you need to to install the board files as noted in [[http://support.sodaq.com/sodaq-one/autonomо/getting-started-autonomo/]].+In order to configure the Autonomo with LoRaBee device, you should follow these steps:
  
-{{ :sodaq_rn2483_2.zip |}}+    - Verify that you have the latest Arduino IDE from [[https://www.arduino.cc/en/Main/Software]] on your computer. 
 +    - Install the board files as noted in [[http://support.sodaq.com/sodaq-one/autonomо/getting-started-autonomo/]]. 
 +    - Add the following library {{ :sodaq_rn2483_2.zip |}} to your Arduino IDE as explained in [[https://www.arduino.cc/en/guide/libraries]]. 
 + 
 +Now you are ready to write a sketch for the device. Here is one example sketch {{ :test-lorawan-combined-loraserver-example.zip |}} where the autonomo is connected to three sensors: light, moisture, and temperature. Let us analyse some extracts of the code. 
 + 
 +In this part, you should put the keys for Over-The-Air Activation (OTAA) as explained in the LoRaWAN specification:  
 +<code c++> 
 +// USE YOUR OWN KEYS! 
 +const uint8_t devEUI[8] = 
 +{ }; 
 + 
 +// USE YOUR OWN KEYS! 
 +const uint8_t appEUI[8] = 
 +{ }; 
 + 
 +const uint8_t appKey[16] = 
 +{ }; 
 +</code> 
 +  
 +The pins for connecting the sensors are specified in these declarations (A0 for light sensor, A2 for moisture sensor, and D0 temperature sensor): 
 +<code c++> 
 +int light_pin = A0; 
 +int moisture_pin = A2;  
 + 
 +int temperature_pin = 0; 
 +int temperature_vcc_pin = 1; 
 +int moisture_vcc_pin = 8; 
 +int moisture_gnd_pin = 7; 
 +</code> 
 + 
 +The OTAA method is used for joining the network and adaptive data rate is activated: 
 +<code c++> 
 +LoRaBee.initOTA(loraSerial, devEUI, appEUI, appKey, true) 
 +</code> 
 + 
 +Eight different sub channels are activated with data rate ranges from 0 to 5: 
 +<code c++> 
 +LoRaBee.configChFreq(0, 868100000L,0,5,1); 
 +LoRaBee.configChFreq(1, 868300000L,0,5,1);  
 +LoRaBee.configChFreq(2, 868500000L,0,5,1); 
 +LoRaBee.configChFreq(3, 867100000L,0,5,1); 
 +LoRaBee.configChFreq(4, 867300000L,0,5,1); 
 +LoRaBee.configChFreq(5, 867500000L,0,5,1); 
 +LoRaBee.configChFreq(6, 867700000L,0,5,1); 
 +LoRaBee.configChFreq(7, 867900000L,0,5,1); 
 +</code> 
 + 
 +Finally, the message is sent in an unconfirmed uplink message: 
 +<code c++> 
 +LoRaBee.send(1, (uint8_t*)message.c_str(), message.length()) 
 +</code>

 +Devices in the LoRaWAN platform can also be used on Arduino boards with Dragino shields. The combined module as well as the basic configuration steps are presented in [[simple_lora_prototype|Simple Prototype of LoRa Communications]]. As for the Autonomo device, you can download the following sketch {{ :test-loraserver-comb-loraserver-dragino.zip |}} and modify it according to your preferences. Here are some extracts of the sketch:
 +
 +Do not forget to insert you keys for the OTAA join method.
 +
 +<code c++>
 +const lmic_pinmap lmic_pins = {
 +    .nss = 10,
 +    .rxtx = LMIC_UNUSED_PIN,
 +    .rst = 9,
 +    .dio = {2, 6, 7},
 +};
 +</code>
 +
 +<code c++>
 +        case EV_TXCOMPLETE:
 +            Serial.println(F("EV_TXCOMPLETE (includes waiting for RX windows)"));
 +            if(LMIC.dataLen) {
 +                // data received in rx slot after tx
 +                Serial.print(F("Data Received: "));
 +                Serial.write(LMIC.frame+LMIC.dataBeg, LMIC.dataLen);
 +                Serial.println();
 +            }
 +            // Schedule next transmission
 +            os_setTimedCallback(&sendjob, os_getTime()+sec2osticks(TX_INTERVAL), do_send);
 +            break;
 +</code>
 +
 +<code c++>
 +LMIC_setTxData2(1, (uint8_t*) buffer, message.length() , 0);
 +</code>
 +
 +<code c++>
 +LMIC_setDrTxpow(DR_SF7,14);
 +</code>
 +
 +<code c++>
 +do_send(&sendjob);
 +</code>
