What is Sigfox?
Sigfox: Global LPWA network Low power, to provide autonomy Global, to be used everywhere Low cost, to address everything Easy to use, and adopted quickly
Backed by large corporations Investors Partners & Customers
LPWA Market size
Sensolus offers an end-to- end tracking solution. It notifies Airbus about its assets’ trips and give insights on supply chain optimization. The device embeds an internal memory to record data when outside of coverage. Problem solved Track spare parts between the headquarters and the sites of its suppliers BenefitsSolution ▪ Cross country tracking without high roaming fees ▪ Real-time visibility on the asset during transportation ▪ Automation of the supply chain Industrial asset management GPS + BLE tracker for indoor and outdoor geolocation LIVE
Sewage monitoring CONFIDENTIAL 7 Reduce cost of waste water testing ▪ Environmentally safe water ▪ Reducing labor costs due to testing ▪ Fresh smell in the city Sea water seeping into the sewers increases salinity and conductivity. By measuring conductivity, it's possible to measure the amount of sea water that has seeped into the sewage system. Ayyeka's Wavelet Wastewater Quality Kit measured the inductive conductivity and salinity of the waste water. Other Ayyeka sensors measure: Turbidity: the cloudiness or haziness of a Fluid ph level: acidity or basicity of the wastewater Oxidation reduction potential (ORP): a measure of the cleanliness of the water Challenge BenefitsSolution Pilot

So.. Which one to choose ? It all depends on the use case! Most important: • SDK? • Other connectivity? • Support? • Price? • Power Consumption? • Availability? • Size?
Antenna : THE most important part PLAN IT WHILE DOING YOUR PCB! • Balance between design & perf • Depends on the use case • Target u0 (+14 dBm or +22 dBm) • Hire an antenna guy if you need so • https://build.sigfox.com/antennas 29
Antennas • Lots of providers on shelves (Molex, Pulse, Linx..) • Can do your own • All depends what you have & need! • Sens’it antenna: open source design https://build.sigfox.com/antennas#antenna-design-example
Antennas ( small feedback) Antenna Price Size Integration Perf Indoor? External YES Internal wire YES Ceramics NO PCB printed YES
Batteries • Sigfox predictability: no signaling, 1 message = X uAh • Different types of batteries = Different Use Cases Rechargeable device? Size constraints? Radio Zone has little impact on battery life • Peak current while transmitting 20 to 50 mA in Europe, 130 to 250 mA in US Coin cell: short lifetime Can work with extra (super)- capacitor circuit Prefer multiple smaller batteries over a big one
Radio zones • RZ1: Europe, MEA 868 MHz, +14 dBm • RZ2: North America, Brazil 902 MHz, +22 dBm • RZ3: Japan, Korea 920 MHz, +14 dBm, LBT • RZ4: South America 920 MHz, +22 dBm
Multi radio zones devices • Hardware Single Zone Different Hardware (modules) Different module version but same pinout/PCB • Hardware Multi Zones Same Hardware, stay in the same zone Set zone during production/firmware flashing • Software Multi Zones: Monarch service Same hardware, moving interzone For specific worlwide asset tracking use cases Require specific Sigfox firmware on chipset (more information coming soon)
Tools
Testing tools • SDR Dongle • End to End testing (not for prod) • RSA (Radio Signal Analyzer) • Included in SDR dongle • Test radio compliance • Litepoint analyzer IQxel-M • RF testing (WiFi, BLE, Sigfox) • Manufacturing tests • Pre-certification
Certification process
• Sigfox VerifiedTM Integration of the Sigfox stack For modules & big volumes Conducted tests 7.5k€ Sigfox ReadyTM For all End Products Radio tests Approx 2.5k€ 38 Certification for Modules & Devices Certified product = Sigfox VerifiedTM + Sigfox ReadyTM
Device Maker journey Select building blocks Build device Validate and Certify Industrialize devices  Samples,  Pilot,  Ramp-up,  Mass-Production Conducted Radiated Ref Design Check Technical Review only Reference Designs Modulation and Protocol certification SoC / Transceivers Modules Type Approval (CE, FCC, ARIB, Anatel…)
Sigfox presentation Sigfox ReadyTM process 40 2 steps process : 1) Do the testing with accredited test houses (<1k€) 2) Once done, Certification Filling with Sigfox automatically trough build.sigfox.com ( 1.5k€ and 1k) • No need for Certification for POCs & prototypes • Can be done very fast.

Sigfox presentation Credentials management 42 ID = unique identifier for radio solutions provided by Sigfox PAC = One-time Security code for ownership management To register a device on the Sigfox backend, you need both codes. • These Credentials are « preloaded » within the modules. • You need to « read » them from the device on the production line to understand which device in which box. (AT command) • Print your own Serial N° on the box : no ID/PAC • PAC code changes when used : owner the device can get the new PAC on the Sigfox backend
Compatibility program
Transceiver Compatibility •Texas Instruments: CC1120, CC1125, CC1310, CC1350 •Silicon Labs : EFR32, EZR32 •Semtech : SX1272, SX1276 •ST : S2LP ( etc.) 44 10K MCU flash left for Sigfox stack Need a Sigfox Verified to integrate the Sigfox Stack

Message received ? http://backend.sigfox.com (check your e-mails to get credentials) Navigate to the devices menu in the top bar Click on the ID of your device Enter the messages menu from the left navigation column
Check device messages
Hello World (again) https://github.com/nicolsc/mkrfox-hello-world #include <SigFox.h> void setup() { SigFox.begin(); short valA = 7700; float valB = 654.32; SigFox.beginPacket(); SigFox.write(valA); //SigFox.write(valB); SigFox.endPacket(); } void loop(){}
Callback setup Device Type menu Click on your device type name Enter the Callbacks menu Select new default callback
Callback status In the Devices > Messages panel, you have a indicator of the callback status (an arrow) Black : in progress Green : Callback OK Red : Callback KO (at least one of the callbacks failed) Click the arrow to display details.
Frame parsing
Sigfox payload display feature Using a « simple » grammar, you can ask Sigfox to parse your incoming data This is done at the device type level
Parsing the Hello World sample Modify the sketch to send 3 values in a same message short valA = 7700; short valB = 128; float valC = 654.32; SigFox.beginPacket(); SigFox.write(valA); SigFox.write(valB); SigFox.write(valC); SigFox.endPacket();
Set a custom grammer valA & valB are shorts : 16 bytes valC is a 32 bytes float valA::uint:16:little-endian valB::uint:16:little-endian valC::float:32:little-endian
Downlink Callback
How does it work? Downlink flag included in Sigfox message 20 sec after first frame transmission, the module wakes up and waits for downlink response (25 sec window)
Downlink Callback setup Automatic callback: Device Type > Informations > Edit Set Downlink mode to DIRECT Enter an 8 bytes value
Sample code Simple change SigFox.endPacket(); to SigFox.endPacket(true); This will request a response from the network
Handle the response https://github.com/nicolsc/mkrfox-downlink void loop(){ while (SigFox.available()) { Serial.print("0x"); Serial.println(SigFox.read(), HEX); } }
Downlink callback To send the response from your own server, change the Downlink mode to CALLBACK Then create a DATA > BIDIR callback Make sure you comply with the expected JSON format
Geolocation
Geoloc callback Simply create a SERVICE > GEOLOC callback, and receive latitude + longitude + accuracy
Geolocation Callback Create a new Service > Geoloc callback Use following URL to center the map: https://maps.googleapis.com/map s/api/staticmap?center={lat},{lng} &zoom=13&scale=1&size=600x300 &maptype=roadmap&format=png &visual_refresh=true
