Very good tutorial. Thank you very much. I am wondering why the maximum SNR value is used as measured SNR? Isn't it safe to use minimum SNR since we have to make sure the worst signal should be able to be received?
All your tutorials are precise and super helpful. So the ADR is something LoRaWAN protocol does automatically between the server and uplink device? Or is this something the device manufacturer does to program the device uplink? This feature is very important as we seek to prolong device battery life.
i am using lora sx1278 connecting with multiple nodes(arduino) how can i differentiate the lora connected to nodes to send sensor data to particular node
Sorry I do not know. My tutorials are about LoRaWAN, communication between end nodes and gateways. See LoRaWAN specification, page 17: lora-alliance.org/sites/default/files/2018-07/lorawan1.0.3.pdf The Frame Header (FHDR) contains the device address (DevAddr). In your situation, the communication is between end-nodes. I have no idea how that works.
Do the header data need to be verified manually on the reciever end or is it done internally and I do not need to worry about it? Comparing the payloadsize etc., and is the header even accessible on the reciever end ?
Excellent explanation

What length of bytes or how many bytes can the payload have as maximum?
Does LoRa not include headers to indicate the identities of the source (transmitter) and the destination (intended receiver)?

Very good videos.
What is 28 in the payload duration formula?
Is payload length equal to size of data comes from sensors?

Saddam Husain Good Question
What is the worst case max payload size? I cant seem to find a number anywhere, and I want to know how small I have to make the packages.
depending on datarate, max payload can be from 11 bytes to 256
thanks
can you please share some pcaps?
Sorry, at this moment I have no time to make packet captures.
