Welcome, Orkhan Amiraslanov (@azerimaker) from The Things Industries!
LoRaLoRaWANClass A, B, C DevicesRichard Ginus (TWTG) came on the show to discuss LoRa based productsThingsUNOThingsNodeJP Norair also worked on LoRaWAN systems, but talked about some of the limitations.The Things StackThe Things NetworkOrkhan is originally from Azerbijian and studied industrial automation and process control.He went to a German research center for AI for graduate workWhile there, his masters thesis involved large (64x64 cm display) Electroluminescent (EL) displays driven by an FPGASimilar to how Ben Krasnow's EL displays work (but larger)SAMR34SX1276Xplained boardOrkhan learned KiCad 2014The 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 frameworkAtmel StudioPorted to PlatformIOElectronicCatsPutting device credentials onto deviceSpreading factorOrkhan said "kB" on the show, but later corrected. Here are the official number51 usable bytes for the slowest data rates, SF10, SF11 and SF12 on 125kHz115 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 LoRaA weather balloon got 750 kMFair use policy mandates no more than 1% transmitting time.Common uses for LoRaWAN is Industry / Smart CityReiner van der Lee made the Vinduino, who Chris met during early SuperconDevice MarketplaceWienke is the CEO of The Things Industries called Orkhan to work on The Generic NodeSTM32WLSemtech licensed the SX1276, so the ST part is a SIP, not a SOC (chips connected by wires)Two version: single/dual coreDual Cortex M4 / M0+Open sourcePower on the Generic Node300 nA quiescent buckDesigned to be low power1.8 uA in sleep modeUsed the Otii to measure sleep/transmit powerCE testing output power100 mW / 14 dBm in the EUUS is 22 dBm (FCC testing)Created multiple outputs to allow different channelsGeneric Node Pricing:Probably will be $70 for low volumeHoping to get to $40 for future higher volume pricingFractus antennaThere will be a Virtual Conference about The Generic NodeThe Things Conference in AmsterdamGeneric Node SDKClock sourcing with STTCXO was a problematic sourcing partFind Orkhan online@AzeriMakerMakertronika Blog Livestream available here:
