#LilyGo has a US$87.35 “pager” that looks exactly like the first-generation BlackBerry but with a better screen (480×222 IPS color), two deployable antennas, and #LoRa support, called the “T-Lora Pager”. It’s advertised as a “LoRa + ESP32-S3 Handheld AIOT Programmable Development Device” and they show it here running #MeshCore. 16MB Flash and 8MB PSRAM. #ESP32

on 02024-07-24#video on telephone #decentralization with apparently some newly available mesh networking firmware, "Meshtastic" #radio running on #ESP32 hardware: encrypted text-based walkie-talkies using #LoRa on the Heltec WiFi_LoRa_32_V3 board, which has an ESP32-S3FN8 on board. Not low-power, though; half a watt idle! And the firmware is built on PlatformIO. You can flash it via #WebUSB on flasher.meshtastic.org. But it depends on a custom app on your cellphone for its UI, to which it communicates over Bluetooth (or USB serial or Wi-Fi), because the actual board only has two buttons, though it does have a respectable OLED screen which displays incoming text messages. It also needs the cellphone if you’re going to give it GPS. You can also use a browser app which uses your Wi-Fi or Bluetooth to talk to your local devices. The YouTuber reports he got messages through (spottily) at 5km from his 32nd-floor highrise balcony, using the 90-bits-per-second data rate, but at ground level at the beach, only about 150 meters of range, which he blames on the antenna. It can share private keys over QR codes to set up an encrypted channel, but by default doesn’t.
a #LoRa protocol stack for something called #LoRaWAN
on 02022-10-12new long-range #radio #hardware "LPWAN" technologies (“Sigfox”, “#LoRa”, “Ingenu”) transmit at kilobits per second over unlicensed spectrum to (in the case of Beep Networks’s LoRa test) a kilometer or two, or 16 km in rural areas with towers.
