You should find your UnaShield in a carton box marked "RCZ4" (Radio Configurations Zone 4, where Taiwan is located). This is very important to recognize your RC Zone, as Sigfox uses different radio frequency in different zones.
After unboxing, attaching antenna to your UnaShield. Later on we'll attach it onto the Arduino board. The version of the shields we have is UnaShield V2S.
On UnaShield there are some sensors already built-in, so users may start collecting data in no time.
- NXP Accelerometer (G-sensor) - MMA8451Q
- BOSCH Temperature/Humidity/Pressure sensor - BME280
Scan the QR code on the board using your mobile phone, you'll get the Sigfox Device ID and PAC (Porting Authorization Code). You should also find the same Device ID next to the QR code sticker.
Then, follow the instructions from step 1 to 7 on this page to activate your UnaShield.
Brief steps of the activation process:
- Go to the Dev Kit Activation page.
- Pick your country: Find "Taiwan" and click on the UnaBiz icon.
- Device information: Enter the Device ID and PAC you just got on your mobile phone.
- Account details: Enter your personal information if it's your first time registering a device.
- Check your mailbox for the activation email. Click the link in the message to complete the activation process.
- Type your password twice.
- You may now login to the Backend Portal.
Please note that UnaShield works best with Arduino Uno. It is not compatible with all variants of Arduino boards due to different pin definitions.
UnaShield V2/V2S -- Arduino Uno pin mapping:
- Push-button → D6 Digital In
- Groove connector #1 → I2C Digital (SCL & SDA), or Analog In/Out (A4 & A5)
- Groove connector #2 → Analog In/Out (A2 & A3)
- User programmable Red LED → D9 Digital Out
- User programmable Green LED → D8 Digital Out
UnaShield sensor to Arduino I2C:
- Accelerometer (G-sensor) → I2C address 0x1C
- Temperature/Humidity/Pressure sensor → I2C address 0x76, Interrupt#1 & #2 (D2 & D3)
In Arduino IDE, make sure you select the correct Arduino board and serial port. Set the serial data rate to 9600.
Download the Arduino library for the UnaShield. Move the uncompressed folder to your Arduino libraries directory. Relaunch Arduino IDE and open the sample sketch: Examples → unabiz-arduino-master → DemoTestUnaShieldV2S.
In the settings of the transceiver object, make sure the variable country is set to COUNTRY_TW.
static const String device = "g88pi"; // Device name if using emulator.
static const bool useEmulator = false; // Turn off emulator.
static const bool echo = true;
static const Country country = COUNTRY_TW; // Country code.Compile and upload the sketch to Arduino. You should get messages of the status of the UnaShield from the serial port (remember to set data rate to 9600).
The transceiver will broadcast Structured Messages every 10 seconds for 10 times. 10-second is the shortest interval between two Sigfox messages. So it's like sending data in burst-mode. This is only for testing the shield for the first time. Ideal settings for daily usage would be 10-15 minutes interval between messages.
If everything works without a hitch, you should see messages in your Backend Portal.
And also you can find the location information in which the coverage of the base station will be shown.
