Welcome, Orkhan Amiraslanov (@azerimaker) from The Things Industries!
  • LoRa
  • LoRaWAN
  • Class A, B, C Devices
  • Richard Ginus (TWTG) came on the show to discuss LoRa based products
    • ThingsUNO
    • ThingsNode
  • JP Norair also worked on LoRaWAN systems, but talked about some of the limitations.
  • The Things Stack
  • The Things Network
  • Orkhan is originally from Azerbijian and studied industrial automation and process control.
  • He went to a German research center for AI for graduate work
  • While there, his masters thesis involved large (64×64 cm display) Electroluminescent (EL) displays driven by an FPGA
  • Similar to how Ben Krasnow’s EL displays work (but larger)
  • SAMR34
  • SX1276
  • Xplained board
  • Orkhan learned KiCad 2014
  • The radio module has a 0.5 mm pitch BGA, but he was able to get it fabbed by oshpark!
  • The form factor Orkhan uses most often is the (adafruit) Feather pinout.
  • Atmel software framework
  • Atmel Studio
  • Ported to PlatformIO
  • ElectronicCats
  • Putting device credentials onto device
  • Spreading factor
    • Orkhan said “kB” on the show, but later corrected. Here are the official number
    • 51 usable bytes for the slowest data rates, SF10, SF11 and SF12 on 125kHz
    • 115 bytes for SF9 on 125kHz
    • ~222 usable bytes for faster rates, SF7 and SF8 on 125kHz (and SF7 on 250kHz)
  • Andreas Spiess reached 149 kM with LoRa
  • A weather balloon got 750 kM
  • Fair use policy mandates no more than 1% transmitting time.
  • Common uses for LoRaWAN is Industry / Smart City
  • Reiner van der Lee made the Vinduino, who Chris met during early Supercon
  • Device Marketplace
  • Wienke is the CEO of The Things Industries called Orkhan to work on The Generic Node
  • STM32WL
    • Semtech licensed the SX1276, so the ST part is a SIP, not a SOC (chips connected by wires)
    • Two version: single/dual core
    • Dual Cortex M4 / M0+
    • Open source
  • Power on the Generic Node
    • 300 nA quiescent buck
    • Designed to be low power
    • 1.8 uA in sleep mode
    • Used the Otii to measure sleep/transmit power
  • CE testing output power
    • 100 mW / 14 dBm in the EU
    • US is 22 dBm (FCC testing)
    • Created multiple outputs to allow different channels
  • Generic Node Pricing:
    • Probably will be $70 for low volume
    • Hoping to get to $40 for future higher volume pricing
  • Fractus antenna
  • There will be a Virtual Conference about The Generic Node
  • The Things Conference in Amsterdam
  • Generic Node SDK
  • Clock sourcing with ST
  • TCXO was a problematic sourcing part
  • Find Orkhan online
    • @AzeriMaker
    • Makertronika Blog

    In terms of the things stack being more for commercial, the company I work for actually found that Chirpstack, which is fully open source, to be easier to manage and easier to host. Some gateways (eg RAK) also come with it pre-installed so to make sure your data is commercially safe
