cziter15 / raesp_gateway

:satellite: A standalone device project featuring SX1278 and ESP8266 components, serving as a radio-WiFi gateway. The primary objective is to provide support for OOK remote power outlets, with the flexibility for potential future integration of LoRa 433 and other communication protocols, thanks to its adaptable hardware.

Range enquiry #1

Open garudaonekh opened 1 year ago

garudaonekh commented 1 year ago

Hi, Interesting idea. Does it have better transmission and receiving range than normal superheterodyne Receiver? My purpose is to use SX1278 to control normal 433mhz switches and also receive data from RF433 sensors. I used to use CC1101 Thanks

To clarify - SX1278 is inside Ra-02. I don't know how it operates versus CC1101. Currently using it to control switches only, so it acts only as a transmitter. I planned to play with LoRA initially, but currently I'm focused on another procject.

It look like only transmission exist. How hard it is to add receiving functions?

cziter15 commented 1 year ago

It depends what protocol is used. Packet-mode should be easy.

ASK mode

garudaonekh commented 1 year ago

What is the maximum distance you can transmit?

cziter15 commented 1 year ago

ASK is only a modulation mode. You probably have to handle the protocol manually, by handling triggered receive interrupt. Check RadioLib and other examples for SX1278.

When it comes to distance - it depends. In LoRA mode this might even be kilometers but depends on antenna configuration and the receiver.
