SympleLink Radio A private star network for intelligent home automation
A star configuration radio network based of free low power devices on ISM 433 band that can achieve over half mile link distance in LOS. These links will bring 1xUART, 1xI2C and 4xIOs in the Peripheral device, fully controlled by the Central device.
This network is meant to fill the gap between WIFI and LoRa. When LoRa has a massive price overhead in the gateway point as well as the nodes have little payload and rare ability for proper online data protection, the Symple Link Peripheral will only connect to it's Central device. When the WiFi doesn't reach the end of the garden for a light switch, a serial port based sensor, or an I2C io expander, the Symple Link will.
Cheap and effective.
The devices have configurable channel, unique key password and respective handshakes, packet retry, adaptative emission power and listen-before-talk ability.
The device can either only talk when talked to, or be set to have automatic transmissions when they have data received on the UART, or their IOs change value.
Each module comes with it's own unique address and default key, which are labelled in the device. The Address label is in at the top near the antenna and the key, in the bottom. There is also a 2D barcode for easy access scan, containing both key and address.
(Specs: 433.075 base frequency, 5khz deviation, 20khz channel distance and 10kbps speed, maximum power of 20dBm with -107dBm sensibility. These devices are not meant as a final product, rather as a prototype for dev speed boosting.)
Have Fun! We always do.
