Can't get nrfConnect to recognize a custom uuid

[kruenheck]

I changed the file, C:\Users\kruenheck\AppData\Roaming\nrfconnect-bluetooth-low-energy\uuid_definitions.json so that it has a new service:

{
"_comment": {
"comment": [
"Add UUIDs for your services, characteristics, and descriptors in this file.",
"The format is the UUID of the item, followed by an object containing the data.",
"'name' is a mandatory handle, while 'format' is optional.",
"Currently the only supported format is 'TEXT', default is 'NO_FORMAT'.",
"The application must be reloaded to access changes in this file."
]
},
"uuid16bitServiceDefinitions": {
"180D": {
"name": "Heart Rate"
}
},
"uuid16bitCharacteristicDefinitions": {
"2A37": {
"name": "Heart Rate Measurement"
},
"2A29": {
"name": "Manufacturer Name String",
"format": "TEXT"
}
},
"uuid16bitDescriptorDefinitions": {},
"uuid128bitServiceDefinitions":
{
"6E400001B5A3F393E0A9E50E24DCCA9E":
{
"name": "UART over BLE"
}
"000023231212efde2323785feabcd123":
{
"name": "My New service"
}
},
"uuid128bitCharacteristicDefinitions": {
"6E400002B5A3F393E0A9E50E24DCCA9E": {
"name": "UART RX"
},
"6E400003B5A3F393E0A9E50E24DCCA9E": {
"name": "UART TX"
}
},
"uuid128bitDescriptorDefinitions": {}
}

But when I look at my device in nrfConnect, it shows the uuid number but not the name

What am I missing?

Hi, 

Please refer to the example to update for your custom UUID.

{
    "_comment": {
        "comment": [
            "Add UUIDs for your services, characteristics, and descriptors in this file.",
            "The format is the UUID of the item, followed by an object containing the data.",
            "'name' is a mandatory handle, while 'format' is optional.",
            "Currently the only supported format is 'TEXT', default is 'NO_FORMAT'.",
            "The application must be reloaded to access changes in this file."
        ]
    },
    "uuid16bitServiceDefinitions": {
        "180D": {
            "name": "Heart Rate"
        }
    },
    "uuid16bitCharacteristicDefinitions": {
        "2A37": {
            "name": "Heart Rate Measurement"
        },
        "2A29": {
            "name": "Manufacturer Name String",
            "format": "TEXT"
        }
    },
    "uuid16bitDescriptorDefinitions": {},
    "uuid128bitServiceDefinitions": {
        "6E400001B5A3F393E0A9E50E24DCCA9E": {
            "name": "UART over BLE"
        }
    },
    "uuid128bitCharacteristicDefinitions": {
        "6E400002B5A3F393E0A9E50E24DCCA9E": {
            "name": "UART RX"
        },
        "6E400003B5A3F393E0A9E50E24DCCA9E": {
            "name": "UART TX"
        }
    },
    "uuid128bitDescriptorDefinitions": {}
}

How is this different from what I'm doing?

[Amanda Hsieh]

There is no uuid128bitCharacteristicDefinitions and name for your custom UUID.  

[kruenheck]

I added characteristics and I still only see numbers on nrfConnect
