Custom Reciever ( autotune to search for transmitter) #654

Open Mdanyalk22 opened 1 year ago

Mdanyalk22 commented 1 year ago

I am new to LoRa. I am wondering if there are multiple sender with different parameters like SF, preamble length, sync word, bandwidth. Is there any technique for a reciever to tune untill it encounter any of the transmitter. Purpose here is not to search for specific transmitter but any. Just want to know if there is such logic exist? Or I have to hard code my reciever??

Thanks

It's not really how LoRa works. There is frequency hoping, where a device "hops" from one frequency to the next, but that's unreliable – while you're on frequency X, another device may transmit on frequency Y. And that's not even taking into account other settings like BW and SF.

If you need to have devices transmitting on different settings, you need to equip your receiver with one module per.
