Hi ,
Below is the response from the team. The Github issue link is: https://github.com/Azure/iotc-device-bridge/issues/63
The device bridge is not directly compatible with the device simulation solution accelerator. The device simulation sends data to an IoT Hub, whereas the device bridge is intended to receive data through HTTP and send it to IoT Central.
The device simulation does not send data through HTTP, so you cannot connect it directly to the device bridge.
