Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

ESP32 GPS LoRa

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right […]

Sony Spresense 6-core MCU Development Board Now Supports Java

Sony Spresense board was introduced in spring 2018 with a 6-core Cortex-M4 microcontroller from the company, GPS & GLONASS, as well as audio support. The breadboard-compatible board could also be inserted into an Arduino UNO R3 compatible base board, and Sony offered support for both the Arduino IDE and a C-based NuttX-based SDK. You’ll find some more details and photos in our “review”. Sony has now partnered with MicroEJ to provide developers with Java support on Spresense board through MicroEJ Virtual Execution Environment (VEE). A Java simulator (VEE Virtual Device) allows you to develop software for Spresense independently of the hardware. Beside plenty of libraries, MicroEJ VEE features MEJ32 32-bit virtual core is compatible with various architectures including ARM Cortex-M, ARM Cortex-Ax, RX, V85, MIPS32, TriCore, and Tensilica. Java enables application portability which means that any GUI/IoT/Security or application code can run on various embedded systems supported by MicroEJ VEE. […]
