What is the new lora-query command for adding nodes in MTCAP

[dibya mohanty]

Hi,

The process I was following to register a device to the gateway was –

“lora-query -a <NET-ADDR> [CLASS] <AppEUI> <DevEUI> <AppKey>”

After a firmware upgrade somehow this does not work any more to register the devices to the gateway. I also tried out the new lora-query utility to figure out how it works following the page here –

LoRa Network Server

Here it mentions to issue curl commands to register the devices.

curl 127.0.0.1/api/loraNetwork/whitelist/devices -X POST –data ‘{“deveui”:”<DevEUI>”,”appeui”:”<AppEUI>”,”class”:”C”,”appkey”:”<AppKey>”}’ -H “Content-Type: application/json”

I am using the OTAA join method and in the link above it is mentioned to use this curl command to register a device.

Using this curl command I get a success status code 200 but somehow when I try to do a device list as follows it does not list the device –
lora-query -x device list

Using the “lora-query -x device add” also fails with the arguments of deveui, appeui and appkey.

The documentation is really confusing and it is hard to register devices and communicate to the gateway

Can anyone please provide me with the right steps to add devices to the gateway and start communication?

The LoRaWAN > Key Management page can be use to enter end-devices and appkeys.

AppKeys are longer stored in the network-server database so the lora-query cannot be used to add them.

They can be added to the API on AEP or the lora-network-server.conf file for mLinux.

The network-server must be restarted after keys have been added to take affect.

The OTA device will not appear in the device list until it has joined the Conduit.

I cannot use the UI for registration since i have to automate the process.

I have an AEP, so that means the curl command is the right way to register?

Restarting the network server everytime adds an additional overhead now.

[Jason Reiss]

Restart is only needed after all keys have been added.
You will also want persist the keys over reset.

Issues API save
$ curl 127.0.0.1/api/command/save -X POST –data “”

Thanks a lot. I was able to add a node using the curl commands and also list then using the curl get command. Now i want to delete a specific node using the curl delete command. How can i do that ?

[Jason Reiss]

Delete by array index is supported
$ curl 127.0.0.1/api/loraNetwork/whitelist/devices/0 -X DELETE –data “”

[dibya mohanty]

This is a bit strange… Can i at least GET a particular node based on deveui or does that also work by array index?

Hi Jason,
I was able to add all the keys based on the curl commands. Now when i see the LoraWan > Key Management i find my device and the keys associated to it.

Now i fail to connect but in the log i find –

2018-05-03T11:57:26.094224+02:00 mtcap lora-network-server: GW:00-80-00-00-00-01-09-78|FRAME-RX|Parsing 1 packets

Can you help me out with what is going wrong here?

[Jason Reiss]

CRC-ERROR is probably not caused by your device.
