Hi @krishna194

Thank you for your interest in the ThingsBoard IoT gateway.

REST connector gives ability to create endpoints on the gateway and listen ports to get information. To take the information from another resource you should use Request connector.

Thanks for the quick response I have a sample rest endpoint server running on my pc with endpoint 127.0.0.1:5000/user/username How to get information with request connector My request configuration is attached below

I have another doubt Whether REST and Request connectors can be enabled at the same time through gateway.?

How to get information with request connector

To get information from some endpoint, you should configure the converter section. It configuration depends on response from server (json/bytes). To get information from it you can use just ${attribute_name} to get attribute_name parameter value from the incoming message or use JSONPathExpression e.g. in case if you get the array of values.

Whether REST and Request connectors can be enabled at the same time through gateway.?

Yes, you can do it. Also you can run several connectors with the same type (e.g. 2 request connectors and one rest connector). To do this uncomment/copy connector section in the tb_gateway.yaml file. Only one requirement - every connector must has his own configuration file.

Thanks for your reply I have another question regarding the ble connector I have a ble simulator on smartphone,parametes like heart rate ,temperature etc I want to get the UUID of these parameters using python script,but it shows connection refused error Can you explain the reason or another method for this?

Hi @krishna194 ,

Please open a new issue, when you wanna ask something new.

Probably, the issue with simulator is appeared because the smartphone usually doesn't support BLE connection to them without pairing, just try to pair device with gateway and your smartphone and try to run the gateway again.
