be the use case? => Local or Wide Area Networks. • Plugged or ba@ery? How long? • Amount of data that will be sent or received by device. • Number of devices to be connected. • Build of Materials -‐ Module Price • Size of Module + Antennas • Ease of integra%on -‐ documenta%on and community
not 100m). • Frequency band => 2.4Ghz • Tx current => 25-‐50mA • Data Rate => 100kbps (and not 1Mbps) • Complexity => Li@le. • Size => very small • Price => Cheap. Tip: want to play with BLE? Check Sensortag.
Telecom Design Eval Kit TD1208 (TD1204 works the same way) Linux & Mac OS Connect to your USB-‐serial port using screen ($ screen /dev/@y.*) Make sure you have the FTDI drivers installed Windows (why not ?) Use PuTTY or another client -‐ Connect to the USB-‐serial port
data buffer over serial (SPI). Shield comes with a library abstrac%ng this, so you just have to SIGFOX.send(buffer) Example using the Atmel Shield to send T° & ba@ery voltage over SIGFOX h@ps://github.com/nicolsc/AtmelSigfoxShieldEx h@p://apidays-‐sigfox-‐demo.herokuapp.com
processing is handled by the SIGFOX backend => You only deal with the raw message you sent + metadata : %mestamp, rssi, deviceId => Data is easily accessible by any of these 3 channels SIGFOX web plahorm REST API HTTP callback pushing new messages to your app
