A taste of MeshCore on an old TTGO LoRa32


MeshCore on an old, unsupported TTGO LoRa32 V1.0: building it from an open pull request, adding USB control, and what the Bulgarian mesh looked like.

Testing a #LoRaWAN node with a solar harvesting module. Sending temp and batt once every 5 min @ SF7. Node is placed near a north facing window, it is showing and completely overcast. 1800 lux measured by phone. Recording battery readouts, will post them in few days. #IoT
Considering doing OTAA once, storing the credentials and using ABP thereafter on my LoRaWAN projects e.g. battery change, reset etc. Rationale: OTAA requires good gateway->node reception, whereas in remote areas this might be hard to achieve. Does this violate some good practice?

Experimenting with WebUSB configuration of a SAMD21 based LoRaWAN node, PoC works very well so far. Will extend with all posible configurations, so just about anyone could customize the settings within a minute or so. Just plug in, configure and go!

Useful LoRaWAN airtime calculator; helps calculate the max daily transmissions per SF/payload size to comply with @thethingsntwrk fair access policy #IoT #TTN #LoRaWAN –> https://docs.google.com/spreadsheets/d/1QvcKsGeTTPpr9icj4XkKXq4r2zTc2j0gsHLrnplzM3I/edit#gid=0

The new #LoRaWAN antenna works pretty well, consistently receiving packets from a Moteino M0+RFM95 with a 82mm plain wire as antenna parked 13km away, SF10, -117dB RSSI. Got sporadic receipts from ~20km away

@thethingsntwrk console shows my #LoRaWAN gateway as offline, friends confirm the same with their gateways. Is it something local?

Finally a proper antenna for my @thethingsntwrk #LoRaWAN gateway.

#SAMD21 based Moteino M0 + rfm95 #LoRaWAN module + SPI flash sleep current around 12uA. Not great, not terrible. Wakes periodically to send data to The Things Network using LMIC Arduino library. #IoT Dropped to 8.5uA with "crystalless" option.. cool 🙂

#3Dprinted an enclosure for a TTGO #ESP32 #LoRaWAN node, not a very good fit though.. will try alternatives

Just received a @LowPowerLab Moteino M0, will use it with the RFM95 #LoRaWAN module I tweeted earlier. Has the SAMD21 Cortex M0 uC, a good chance for me to learn more about these. #IoT

Received few RFM95 #LoRaWAN modules to experiment with #IoT

Ordered a 80cm 5.8dBi antenna for my @RAKwireless RAK2247 based #LoRaWAN gateway.

Moved my TTN #LoRaWAN gateway to the roof, should have much better coverage than indoors.

Drove around Sofia and suburbs with one of @boyannedkov #LoRaWAN GPS trackers, impressive coverage for a 20mW RFM95 transmitter. Managed to reach a gateway 32km away, practically no blind spots. External antenna, pictured below. #ttn #ttnmapper

Completed a 4 EUR #LoRaWAN gateway enclosure for outdoor use using PVC fittings. Apart from the aesthetical crime being committed, it is pretty cool. #IoT

My TTN LoRaWAN gateway is up and running. Next steps are finding proper antenna and outdoor enclosure. #lorawan

Just ordered a @PiSupply LoRa Gateway HAT for Raspberry Pi (RAK 2247 based). Planning on using it for a @thethingsntwrk gateway. #IoT
Considering creating a new LoraWAN based product family, targeting industrial and agricultural IoT

It lives! #esp32 + 480*320 ILI9488 #TFT with touch + #LORA (not yet populated on the PCB) + RTC + piezo buzzer
TO-DO: research project feasibility: swap the RFM69 for a LoRaWAN on my #ESP32 TFT project and use it as SIM-less urban car telemetry/location tracker
