So what it is ? Is it radio ? How does the signal propagate ? What is the range ? Which bandwidth ? Can you explain with more details ? Which material do we need ? Thanks
Industrial imperialist technology. This communication is owned by chip manufacturers. Nobody else can make anything compatible from scratch. HDMI and DAB+ radio are different examples.
@@manuell3505 I'm fine with it. Seems the price is reasonable to make super cheap stuff and at least we get the technology, which was nowhere to be found prior. If we need a free version of it then we can make it ourselves, but as it stands there's no point.
According to wikipedia, it operates just below 1 GHz, so it is Ultrahigh Frequency (UHF) radio, and also has 2.4 GHz capability presumably making it compatible with WiFi. Range can be up to 30 miles line of sight. It does not bounce off the ionosphere because that applies to VHF frequencies (30 - 300 MHz). The signal propagates like any radio signal, but it is modulated using a spread spectrum technique. Modules by Reyax can be controlled by an Arduino using "AT" commands, which are basically strings sent in serial following the AT format. But the specifics may depend on the module and company. LoRa supposedly draws very little battery and can last for years, but in practice it would depend on the current draw of the whole system running off of a battery. If paired with an Arduino, which has a battery life of a few days, the Arduino becomes the limiting factor in battery life. One would have to design a minimal system to perform the desired task at low current draw in order to take advantage of the battery life.
I am happy to using LoRa module for digital data transmission in Toyota but currently I am facing an issue regarding my receiver is not receiving data packets , while transmitter is perfectly sending data and all connections are right!!
Would you please help me out to resolve the issue!!

Hi I’m a small business owner. I use a boat to analyses river water quality. I need a small devices to view, send and log live data from 4-20mA outputs to my computer and also the gps position of the moving device. Do you have such device ?
