Message polled from server

[liuyinze]

Hi all,

It's me again. This time I do have obtained something from server and everything seems to be "fine". But actually some important message is missing and I don't know why.

Here is what I have achieved:

1. Using const char* websockets_server_host = "wss://env779703.eu-latest.cumulocity.com/notification2/consumer/?token=mytoken&consumer=testSubscriber" to connect.
2. Obtained the response from server as following:

 {"self":"https://env779703.eu-latest.cumulocity.com/measurement/measurements/52344","time":"2022-07-27T15:46:44.000+02:00","id":"52344","source":{"self":"https://env779703.eu-latest.cumulocity.com/inventory/managedObjects/1825","id":"1825"},"type":"c8y_SignalStrengthWifi"}
COqyBBAlIAAwAQ==
/env779703/measurements/1825
CREATE

And I tried with python with websocket-client package. The result is as following:

CJi0BBDYByAAMAE=
/env779703/measurements/1825
CREATE
{"self":"https://env779703.eu-latest.cumulocity.com/measurement/measurements/71828","time":"2022-07-28T10:34:36.000+02:00","id":"71828","source":{"self":"https://env779703.eu-latest.cumulocity.com/inventory/managedObjects/1825","id":"1825"},"type":"c8y_SignalStrengthWifi","c8y_SignalStrengthWifi":{"rssi":{"unit":"dBm","value":-63.0}}}

The part

"c8y_SignalStrengthWifi":{"rssi":{"unit":"dBm","value":-63.0}}

is missing while using the library WebSockets2_Generic.

I am wondering the body

{"self":"https://env779703.eu-latest.cumulocity.com/measurement/measurements/52344","time":"2022-07-27T15:46:44.000+02:00","id":"52344","source":{"self":"https://env779703.eu-latest.cumulocity.com/inventory/managedObjects/1825","id":"1825"},"type":"c8y_SignalStrengthWifi"}

is not the correct one or the correct one is not sent by the server?

It would be appreciated if someone can help me!

Hi @liuyinze

Sorry I don't have time or way to duplicate the issue. You're on your own now.

I suggest you post for help on Arduino Forum, with Minimal, Reproducible Example. Otherwise, nobody can help without duplication.

If possible, you can also post the differences in the requests sent to server by this library and the python websocket-client.
