Question:
Defining a device with multiple topics with Fiware-IoTAgent

Description:
I have a sensor device. There are 2 topics under this sensor device. I want to listen to the topics and sensor attributes of this sensor device using fiware-iotagentjson. But I don't know how to send a request to fiware-iotagentjson for this device.
I use this docker-compose.yml:
version: "3.8"
services:

1. Orion is the context broker
   orion:
   image: fiware/orion:$ {ORION_VERSION}

   hostname: orion
   container_name: fiware-orion-pms
   networks:

• default
  expose:
• "$ {ORION_PORT}"
  ports:
  - "${ORION_PORT}

  :$

  {ORION_PORT}" # localhost:1026
  command: -dbhost ${IP_ADDRESS}:27030 -logLevel DEBUG -mqttTimeout ${ORION_MQTT_TIMEOUT} -t 255
  environment:
  - ORION_LOG_DEPRECATE=true
  healthcheck:
  test: curl --fail -s http://orion:${ORION_PORT}

  /version || exit 1
  interval: 5s
  restart: always
  iot-agent:
  image: fiware/iotagent-json:3.3.0
  hostname: iot-agent
  container_name: fiware-iot-agent-pms
  networks:

• default
  expose:
• "$ {IOTA_NORTH_PORT}"
  ports:
  - "${IOTA_NORTH_PORT}

  :$

  {IOTA_NORTH_PORT}" # localhost:4041
  environment:
  - IOTA_CB_HOST=${IP_ADDRESS} # name of the context broker to update context
  - IOTA_CB_PORT=1026 # port the context broker listens on to update context
  - IOTA_NORTH_PORT=4041
  - IOTA_REGISTRY_TYPE=mongodb #Whether to hold IoT device info in memory or in a database
  - IOTA_LOG_LEVEL=DEBUG # The log level of the IoT Agent
  - IOTA_TIMESTAMP=true # Supply timestamp information with each measurement
  - IOTA_CB_NGSI_VERSION=v2 # use NGSIv2 when sending updates for active attributes
  - IOTA_AUTOCAST=true # Ensure Ultralight number values are read as numbers not strings
  - IOTA_MONGO_HOST=${IP_ADDRESS} # The host name of MongoDB
  - IOTA_MONGO_PORT=27030 # The port mongoDB is listening on
  - IOTA_MONGO_DB=iotagentul # The name of the database used in mongoDB
  - IOTA_MQTT_HOST=${MQTT_HOST} # The host name of the MQTT Broker
  - IOTA_MQTT_PORT=1883 # The port the MQTT Broker is listening on to receive topics
  - IOTA_DEFAULT_RESOURCE=
  - IOTA_PROVIDER_URL=http://iot-agent:${IOTA_NORTH_PORT}
• IOTA_DEFAULT_TRANSPORT=MQTT
  healthcheck:
  interval: 5s
  restart: always
  networks:
  default:
  labels:
  org.fiware: 'fiware-networks-pms'
  ipam:
  config:
• subnet: 172.50.1.0/24

If I have a device like below:
test:CD99{
ENV
Data =

}

I use the following curl for the device given above and similar and the device is registered to mongo successfully. Curl is:
curl --location 'http://192.168.2.205:4041/iot/devices' \
--header 'fiware-service: acd' \
--header 'fiware-servicepath: /pa/DEVICE31' \
--header 'Content-Type: application/json' \
--data '{
"devices": [
{
"device_id": "PA_DEVICE31",
"entity_name": "PA_DEVICE31",
"entity_type": "pa",
"transport": "HTTP",
"timezone": "Europe/Istanbul",
"attributes": [

],
"static_attributes": [

],
"explicitAttrs": true

}
]
}'

mongo data:

I currently have a device that comes in the following json structure. There are 2 topics under this device. There are sensors under every topic.
test:CD99{
ENV
Data ={
"OT_LOW_BUFF_RESET_CNT": 0,
"COAP_AA": 0,
"NRFX_AA": 28,
}
RSSI
Data={
{
"DA1C1C": "-37",
"000000": "0"
}
}

If I have a device with the above data structure, how should I prepare a curl for this device?
