LoPy Nano-Gateway Extended (Timeout and Retry)
-
Hi @Butch
There's previously was a small bug in the gateway and node code where you need to specify the spread factor (e.g. sf=7).
This has since been patched in the latest firmware release, please try to update your device and your code should now work!
Cheers!

@Butch said in LoPy Nano-Gateway Extended (Timeout and Retry):
I've tried the examples, but I am not having any success. The gateway is not receiving any messages with length > 0. To the best of my knowledge, there are no other LoRa devices in use, and I am using only one gateway and one node.
Any suggestions on how to debug this?
Thanks!
Following up on my own post (poor form, I know, but what to do?), I thought I'd provide more information:
- I am trying to use one LoPy on an expansion board with antenna as a gateway, and one with the same setup as a node.
- I am running this code on the gateway (http://pastebin.com/PDCnq2gF) and this on the node (http://pastebin.com/Ztf5QMWY).
- I am seeing constant messages of zero length being received on the gateway:
Starting LoRaNanoGateway Received message, length = 0 Received message, length = 0 Received message, length = 0 Received message, length = 0 Received message, length = 0 Received message, length = 0
- I am seeing no acknowledgements on the node:
Starting LoRaNanoNode on device 1 Sending a message from device 1 MESSAGE FAILED Sending a message from device 1 MESSAGE FAILED Sending a message from device 1 MESSAGE FAILED Sending a message from device 1 MESSAGE FAILED
I have tried four different LoPy's in two different physical locations, so I don't think I'm having any RF pollution issues.
I could really use some help with this.
Thanks!

Hello Roberto,
Where do I change the band?
I don't see it in your scripts

Thank you for these examples!
Could you add a print(msg) in the gateway code?
It is more consistent with the previous example, and you know quicker that it works (should have started after the coffee this morning :-) )

Thanks, I'll prove it
