Sometimes I’m using an SDR with spectrum scanner to see if a device sends data which is not received by a gateway. However to find out WHAT has been transmitted by the device (bullet 3 & 4), you do need a gateway.
Thanks for update.
Would you please provide any reference document for using SDR in spectrum scanner, that would be very helpful for many of us in real life debugging.
See its “kick-starter” page which has information on when next batch of boards will be for sale - you can preorder for 2/22 delivery.
For a $100 more, you get its big-brother HERE - the demo of it playing FM stations is simply breathtaking, if you’re old enough to be writing your own games in 6502 assembler as a kid
Realistically it’s probably better to create test traffic at the location of interest, rather than to try to sniff what’s already there.
Eg, what you want is a laptop with mobile internet watching the raw traffic feed for the gateway, and then an ABP test node with serial debug output connected to the same laptop.
Did the node transmit?
Did the gateway hear it?
Did the network server get that report?
Did the network and application servers successfully decode it?
Should the network server have sent anything back down?
Did it push a transmit command to the gateway?
Did the gateway transmit that downlink?
Did the node receive it?
