command sending API problem

while i am sending command using traccar API it's working fine for the given :

868450045051396 (GT06)

but the same API for the given device not working ...

017018462864 (Hubao)

developers kindly help me out to resolve this.

What's the problem exactly? Is there an error? You have to provide more details.

Illegal hexadecimal character # at index 3 - DecoderException (... < DataConverter: 29 < BaseProtocol: 100 < ActiveDevice: 55 < ...)

The error means that the format you're using is wrong.

we are using given below for calling api --

curl --location 'http://{IP}:8082/api/commands/send' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic {dynamic token code}' \
--data '{
     "deviceId": 17018462815,
    "type": "custom",        
      "attributes": {

      "data": "{Command}"   
 }
}'

I'm talking about the "{Command}" in your example. That format is incorrect.
