Java gRPC device creation missing OTAA

[Nizero-cmd]

Hello everybody,

I’m working with the chirpstack-api 4.5.1 library for java.

I’m able to create a device, gateway, application, device profile ecc…

I only have an issue when creating a device, the OTAA key is missing after the succesful creation:

public void createDevice(Device device) {
        Device deviceObj = Device.newBuilder()
                .setName("Java-Sensor")
                .setDevEui("0104032b030228b9")
                .setJoinEui("3c530c132b106ab8413917b6c124fe440")
                .setDescription("Description from java!")
                .setApplicationId("2d7f33ea-8b90-4312-b665-23be7716a29d")
                .setDeviceProfileId("9b2ed11e-2376-4ec4-974b-78fe6530b14e")
                .setSkipFcntCheck(false)
                .setIsDisabled(false)
                .build();

        CreateDeviceRequest deviceRequest = CreateDeviceRequest.newBuilder().setDevice(deviceObj).build();

        DeviceServiceGrpc.DeviceServiceBlockingStub stub = DeviceServiceGrpc
                .newBlockingStub(channel)
                .withInterceptors(MetadataUtils.newAttachHeadersInterceptor(metadata));

        stub.create(deviceRequest);
        LOGGER.info("Device created!");

From the chirpstack gRPC documentation, it seems to be set with setJoinEui() method, which i’m using.

Anyone had a similar problem?

Thanks

From the chirpstack gRPC documentation, it seems to be set with setJoinEui() method, which i’m using.

The JoinEUI is something completely different. Please refer to the LoRaWAN specification. What you are looking for is is the CreateKeys method:

https://www.chirpstack.io/docs/chirpstack/api/api.html#api-DeviceService

This step is optional, as one might use an external join-server.

Thanks, it worked!

If I may ask, where did you get the chirpstack-api 4.5.1 library for java from ?
is it in a maven repo somewhere ?
