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 (64x64 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
