Question

我到处都在寻求解决方案，但是我被困住了。

我的设置如下：

ESP32使用BLE GATT NOTIFICATION特性将温度数据通过物联网网关推入物联网。一旦建立了BLE连接，第一个遥测包就会显示在新创建的设备的“最新遥测”区域中。如果我打开网关调试，则可以看到进一步的通知到达thingboard，如下所示：

{"LOGS":"2020-07-20 02:04:19,640 - DEBUG - [ble_connector.py] - ble_connector - 321 - Notification received from device {'device_config': {'name': 'Esp32 v2.2', 'MACAddress': '24:62:AB:F3:43:72', 'telemetry': [{'key': 'temperature', 'method': 'notify', 'characteristicUUID': '0972EF8C-7613-4075-AD52-756F33D4DA91', 'byteFrom': 0, 'byteTo': -1}], 'attributes': [{'key': 'name', 'characteristicUUID': '00002A00-0000-1000-8000-00805F9B34FB', 'method': 'read', 'byteFrom': 0, 'byteTo': -1}], 'attributeUpdates': [{'attributeOnThingsBoard': 'sharedName', 'characteristicUUID': '00002A00-0000-1000-8000-00805F9B34FB'}], 'serverSideRpc': [{'methodRPC': 'rpcMethod1', 'withResponse': True, 'characteristicUUID': '00002A00-0000-1000-8000-00805F9B34FB', 'methodProcessing': 'read'}]}, 'interest_uuid': {'00002A00-0000-1000-8000-00805F9B34FB': [{'section_config': {'key': 'name', 'characteristicUUID': '00002A00-0000-1000-8000-00805F9B34FB', 'method': 'read', 'byteFrom': 0, 'byteTo': -1}, 'type': 'attributes', 'converter': <thingsboard_gateway.connectors.ble.bytes_ble_uplink_converter.BytesBLEUplinkConverter object at 0xb4427eb0>}], '0972EF8C-7613-4075-AD52-756F33D4DA91': [{'section_config': {'key': 'temperature', 'method': 'notify', 'characteristicUUID': '0972EF8C-7613-4075-AD52-756F33D4DA91', 'byteFrom': 0, 'byteTo': -1}, 'type': 'telemetry', 'converter': <thingsboard_gateway.connectors.ble.bytes_ble_uplink_converter.BytesBLEUplinkConverter object at 0xb4427eb0>}]}, 'scanned_device': <bluepy.btle.ScanEntry object at 0xb443a290>, 'is_new_device': False, 'peripheral': <bluepy.btle.Peripheral object at 0xb58f0070>, 'services': {'00001801-0000-1000-8000-00805F9B34FB': {'00002A05-0000-1000-8000-00805F9B34FB': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a210>, 'handle': 2}}, '00001800-0000-1000-8000-00805F9B34FB': {'00002A00-0000-1000-8000-00805F9B34FB': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a270>, 'handle': 21}, '00002A01-0000-1000-8000-00805F9B34FB': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a1d0>, 'handle': 23}, '00002AA6-0000-1000-8000-00805F9B34FB': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a2b0>, 'handle': 25}}, 'AB0828B1-198E-4351-B779-901FA0E0371E': {'0972EF8C-7613-4075-AD52-756F33D4DA91': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a6b0>, 'handle': 41}, '4AC8A682-9736-4E5D-932B-E9B31405049C': {'characteristic': <bluepy.btle.Characteristic object at 0xb443a5f0>, 'handle': 44}}}} handle: 42, data: b'25.00'"}
我要更新的数据是字符串“ 25.00”

我知道我可以直接更新Thingboard，但是我感兴趣的是使用BLE，因为我喜欢传感器与工作无关。

我的问题是，为什么即使到达东西板上也不会显示更新的温度，并且我可以进行哪些更改以使其实现。

任何帮助都非常感谢。整个周末我都在努力。

通过物联网网关的BLE遥测数据未在物联网中更新
