[HELP] Can't access data with Bacnet

[mgruenberger21]

Hello,

I cantt access data of a heating system with bacnet using thingsboard-gateway. When I use Yabe, I can accesss all the things I want to know. But when requesting data with thingsboard-gateway, I dont get any answer of the heating system to my request.

e.g. the request for this value shold look like this I think: { "general": { "objectName": "tb-gateway", "address": "0.0.0.0:47808", "objectIdentifier": 599, "maxApduLengthAccepted": 1476, "segmentationSupported": "segmentedBoth", "vendorIdentifier": 15 }, "devices": [ { "deviceName": "BACnet Device ${objectName}", "deviceType": "default", "address": "IPADDR:47808", "pollPeriod": 10000, "attributes": [ { "key": "Außentemperatur Kessel 1", "type": "double", "objectId": "analogInput:239", "propertyId": "presentValue" } ] } ], "logLevel": "DEBUG", "name": "Bacnet", "enableRemoteLogging": true, "id": "ac5e542d-623b-432a-9a96-04fe82655e34" }

tcpdump:

Can someone please help me to solve this problem.? Sorry, I´m not really a bacnet-specialist.

Try changing this IP address

{ "general": { "objectName": "tb-gateway", "address": "0.0.0.0:47808",

To be the IP address of the network interface of your TBGW.

Hello,

thank you for your message. Still there is no answer of the Bacnet-Device. Looks like something is wrong with the request itself. In Wireshark I can see the request sent to bacnet-device, but nothing is sent back: Some flags look differnet in yabe-request:
