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

A proper antenna for my LoRaWAN gateway
Finally a proper antenna for my @thethingsntwrk #LoRaWAN gateway.
Daylight Saving Time nonsense again
Ah, that Daylight Saving Time nonsense again..
pi+3.5″ 3D printed enclosure won’t close
Fail of the day: @adafruit 's pi+3.5" 3D printed enclosure won't close. I have their older 3.5" TFT+touch version though, this was designed for the newer one.

The 170 EUR Hikvision thermal camera arrived, impressive 160×120@25fps quality
Debugging TTN/LMIC code with my new Atmel-ICE
Debugging TTN/LMIC code with my new Atmel-ICE in @PlatformIO_Org, no more serial/LED for debugging 🙂
Atmel-ICE on my desk
An Atmel-ICE landing on my desk @MicrochipTech, guaranteed fun time ahead. Planning on fiddling with Cortex M0 bootloaders as a starter.

RFM95 with a simple 82mm wire as antenna
RFM95 with a simple 82mm wire as antenna has a much better range than the ESP32 TTGO LORA module with uFL antenna. Less is more? #LoRaWAN #IoT
SAMD21 based Moteino M0 + rfm95 LoRaWAN module
#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 🙂

Non-standard PCB thickness of 1.3mm on the Moteino M0
Wondering why @LowPowerLab Felix decided to use non-standard PCB thickness of 1.3mm on the Moteino M0, can't use a standard RPSMA connector
3Dprinted an enclosure for a TTGO ESP32 LoRaWAN node
#3Dprinted an enclosure for a TTGO #ESP32 #LoRaWAN node, not a very good fit though.. will try alternatives
SAMD21D as a mass storage device
Experimenting with SAMD21D posing as a mass storage device using @Adafruit's TinyUSB library – planning on using this feature to expose configuration JSONs #IoT Added external SPI flash and using it as R/W mass storage device, works nice and smooth 🙂 Firmware configurations are now esposed as JSON file when you plug it in a…
Moteino M0 and RFM95 LoRaWAN module
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
RFM95 LoRaWAN modules to experiment with IoT

80cm 5.8dBi antenna for my RAK2247 based LoRaWAN gateway
Ordered a 80cm 5.8dBi antenna for my @RAKwireless RAK2247 based #LoRaWAN gateway.
TTN LoRaWAN gateway on the roof
Moved my TTN #LoRaWAN gateway to the roof, should have much better coverage than indoors.
Sofia and suburbs with one of @boyannedkov #LoRaWAN GPS
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

3DBenchy printed in 1h 45min
#3DBenchy printed in 1h 45min, using 100% default settings as I have no clue what they mean yet. Result is pretty good for what I care. Creality Ender 3 V2, Cura

Just received a Creality Ender-3 V2 3D printer, my first. Hope it works well.
IoT and engineering stuff
Stocking on gadgets in anticipation of another lockdown in the winter.. mostly IoT and engineering stuff. The bad thing is my Aliexpress wishlist has ~200 more items..
4 EUR LoRaWAN gateway enclosure for outdoor use
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
GCC based SDK
@Flashoholic Just heard back from Dialog Semi: "we are working on a GCC based SDK but this is not public yet and not ready to be released." – That's great news
