RadioShuttle Network Protocol is an Efficient, Fast & Secure Alternative to LoRaWAN Protocol

LoRaWAN protocol is one of the most popular LPWAN standards used for the Internet of Things today, but some people found it “lacked efficiency, did not support direct node-to-node communication, and was too costly and far too complicated for many applications”, so they developed their own LoRa wireless protocol software called RadioShuttle, which they claim is “capable of efficiently sending messages in a fast and secure way between simple LoRa modules”. Some of the key features of the protocol include: Support for secure or insecure (less time/energy) message transmission, multiple messages transmission in parallel Unique 32-bit device ID (device number) per LoRa member, unique 16-bit app ID (program number for the communication) Security – Login with SHA-256 encrypt password; AES-128 message encryption Air Traffic Control – Nodes only send if no LoRa signal is active on that channel. Optimized protocol –  Message delivery within 110 ms (SF7, 125 kHz, free channel provided); default LoRa bandwidth 125 kHz (125/250/500 kHz adjustable), …

Microchip based Orange LoRa Explorer Kit Connects to Orange’s own LoRaWAN Network

You’d think Telecom operators with all infrastructure in place would focus their IoT efforts on LTE Cat M1 or LTE Cat NB-IoT, but Orange has setup its own LoRa network in France with the aim of achieving national coverage by December 2017, at which time they’ll also test interconnection and roaming with other European operators. The company has also launched the LoRa Explorer Kit based on Microchip solutions, and designed by SODAQ. Orange LoRa Explorer Kit specifications: MCU – Microchip Atmel SAMD21 ARM Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB RAM, up to 16KB EEPROM by emulation Storage – 4Mbit serial flash (Microchip SST25PF040C) Connectivity Microchip RN2483A LoRa module + PCB antenna Microchip RN4871 Bluetooth 4.2 module (BLE) with ceramic antenna Security – Microchip ATECC508A1 crypto chip to securely store LoRa keys. USB – 1x micro USB port for charging and programming Expansion – “Arduino M0” compatible headers with 10-bit ADC, 20x GPIOs, I2C, etc… Misc – MCP97001 temperature sensor; RGB …

OpenDime is a Bitcoin USB Stick based on Microchip SAMD21 MCU, and ATECC508A Security Chip

The first time I heard about crypto currencies, specifically Bitcoin, was probably around 2011, and later in May 2012, I noticed a “micro-payments with Bitcoin digital currency” talk at a Barcamp. I did not think much of it at the time, but with hindsights, I should definitely have started to mine some Bitcoins considering the price was $5. Nevertheless, cryptocurrencies appear to be here to stay, and while most transactions occurs over the Internet, Opendime project has made a hardware USB dongle to store Bitcoins, and earlier this year, announced version 2 of their “Verified Bitcoin Credit Stick”. Hardware specifications of OpenDime v2.0 / v2.1 USB stick: MCU – Microchip / Atmel SAMD21 Cortex M0 MCU Security Chip – Microchip / Atmel ATECC508A Crypto chip with support for SHA-256, TRNG, and public key signing (ECDSA) USB 2.0 interface to connect to a computer Bitcoin seal The USB stick works like a piggy bank, you can add Bitcoins to it changing …

Review of Wio Tracker with GPS, Bluetooth 3.0 and GSM Connectivity

Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches. Wio Tracker Unboxing All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules.

OpenH PULSAR and QUASAR Boards Add 4G LTE Cat M1, or Cat 4/1 to Raspberry Pi Boards

We’ve seen a bunch of IoT boards with 2G connectivity recently including Orange Pi 2G-IoT, Wio GPS, and Nadhat, but while in some countries 2G will still work for many years, those boards are already obsolete – or soon will be – in many other countries. However, finding low cost 3G / 4G  boards is more difficult, and while one solution is to use 3G or 4G USB dongles,  “OpenH – Open Hardware” – part of KLiP Industries – has designed two boards with 4G connectivity provided by Quectel modules. OpenH PULSAR Board PULSAR board is compatible with Arduino Zero and features the following specifications: MCU – Atmel/Microchip SAMD21 ARM Cortex M0+ MCU (the as the one used in Arduino Zero) Connectivity 4G LTE  Cat M1 modem with GPS (Quectel BG96-NA); No external antennas required Bluetooth and NFC Security – Dedicated management CPU with crypto engine Power Supply 10W digital power supply and battery charger with direct solar input FCC and Carrier certified The board can work in standalone mode, but …
