Range enquiry

[garudaonekh]

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]

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

ASK mode

What is the maximum distance you can transmit?

[cziter15]

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.
