Class C devices are not receiving direct messages about iotedge-lorawan-starterkit

[ronniesa]

From a first look this class C device did not join the network as this part should contain the valid keys that were generated during a join and not empty:
"reported": {
"AppSKey": "",
"NwkSKey": "",

Did the device try to do the join?

[gerfen]

@ronniesa I just forced a rejoin on one of the devices. Here's the updated log for that event:

[gerfen]

[ronniesa]

Ok much better :-) can you check if in the reported twin the keys are populated?

[gerfen]

Yes they are. I can share them if they would be helpful.

[ronniesa]

Join looks good then. Does the device has setting for rx2? If yes can you post it. My guess is some mismatch on dr etc as the msg leaves the gateway but seems to be ignored by the device

[gerfen]

This is how I have the devices configured:

[gerfen]

@ronniesa I'm still not able to receive messages with these new Class C devices. Do you have any other ideas as what the issue might be?

[gerfen]

@ronniesa I'm not sure if this will be helpful or not but the tech support team from Ursalink sent me this document for sending direct messages:

MQTT Remote Control DO.pdf

[ronniesa]

@gerfen So the device is able to join and send msg upstream so we know that the device can receive msg (join accept) and can send msg like join request and normal call home msg. This means that all the keys etc. are correct.

The RX2 DR and Freq seems also to match between the down msg and the settings you posted.
Are you sure that the device expect the down msg using port 55?
I would try with a confirmed down msg to see if the device is answering back.

Also does the device have kind of terminal/debug that you can see what is going on?

[ronniesa]

@gerfen in the doc above you can see that they send msg on port 85 and as confirmed:

For UC1122&UC1152
Set DO1 high
{"confirmed": true,"fport": 85,"data": "CQEA/w=="}
Set DO1 low
{"confirmed": true,"fport": 85,"data": "CQAA/w=="}
For UC1114
Set DO1 high
{"confirmed": true,"fport": 85,"data": "CQEA/w=="}
Set DO1 low
{"confirmed": true,"fport": 85,"data": "CQAA/w=="}
Set DO2 high
{"confirmed": true,"fport": 85,"data": "CgEA/w=="}
Set DO2 low
{"confirmed": true,"fport": 85,"data": "CgAA/w=="}

[gerfen]

@ronniesa This morning I was able to get the device to respond to the DO1 high command but I had to take the base64 encoded string and decode it first before sending.

The gateway sees this:

So that's some progress. What I can't wrap my head around is why the older versions of the devices respond to just sending a command string like "CurtainUp". I probably need to encode that string differently but I'm not sure how.

[ronniesa]

Cool, I thought it was not a ntwsrv issue as the join and dr are all good. Honestly I find it strange that the device use strings as it is a waste of bandwidth normally you would use some bits for this like 0 and 1.... you should ask the device manufacturer what did they change.

[gerfen]

Unfortunately they claim they didn't change anything. That said I can live with sending the DO commands along with a duration. If I can do that I will be good to go.

Thanks for the assistance.

[gerfen]

@ronniesa So Ursalink has indeed change their firmware. I need to send the command as a hex string which starts with FF12 followed by the length of the command string. For example if I want to send "test" as a command the hex string would look like this: FF120474657374.

After getting the hex string I needed to convert it to base64 encode and then use the "rawPayload" property to send the direct method. With all of those changes I can now control the devices as I had before.

Thank you so much for helping me dig through all of this. I really appreciate the help!

[ronniesa]

@gerfen glad that you found the issue, no problem you also helped us a lot in the past especially with the US frequencies.
