LoRa transceiver

Hi Kutil,

You won't get long-range reception of garage key and other sensors. That's because they don't use LoRa, so your LoRa receiver chip will be operating in normal FSK reception mode. In which case, you may as well use any 433MHz receiver that you can obtain code for.

Thanks,

and what about short range reception ( 100 m ) ? In parameters I found parameter - mode - LORA, I think when I'll somehow change it, I'll receive a signal for short distance. My goal is identify each of transmiters only, not decode. Is it possible with this device ?

Hi Kutil,

Could you clarify what you mean by identify and not decode? There may be other (easier) ways to achieve what you need, but I just want to be sure of your requirement.

You just want to see the yes/no presence of any nearby radio transmissions at certain frequencies? What is the end goal? This will help too, to find you the best solution.

  "Identify" in this case means to monitor each of sensors and if any sensor is active assign an identifier. My device stores this data for analisis later. This is my goal, improve range of my receiver / data loger.  I know, is easier and cheaper solution to detect remote controls and sensors but I bought this LoRa device and I want use it ( and learn how to configure SX1278 )

What you're asking for doesn't likely exist for ordinary home/commercial use.

From what I can tell, you're seeking not to decode, but to identify (perhaps based on a unique signature) different, perhaps unknown, radio devices, and assign them identifiers so you can see when they transmit again.

The devices don't transmit on a single frequency, they instead use a channel (different channels, depending on the manufacturer) in the 433MHz band. A transceiver device like the one you mention cannot receive multiple channels simultaneously.

What you're actually seeking is some way to collect information from all channels in the 433 MHz band, and analyze it to identify the same signatures or new signatures. This requires different hardware, and software that won't really fit in an Arduino. Funnily enough, the cheaper ebay receivers may perform better than the SX1278, because they will have a wider bandwidth (due to poorer quality filter). Range will suffer, but you may not need to be tuned into a precise channel.

Anyway, if you still intend to use the SX device, I don't have code for SA1278 or CC1101, but you should be able to find some code on the Internet and port it if needed. I just think it won't help you achieve the requirement (from what little I understand of your requirement), so you may want to be sure of this before spending time porting code.

Ok ,

I thought LoRa bandwidth could somehow be set for my purpose, but it's probably not possible.

Thanks.
