Hi,

They are all optional, use those you feel are useful for your product. If you don't have a Organizational Unique ID, you don't need to use this.

[quote user="Sreejith Sundh"]Also confused from the GLS service that they defined MODEL NUMBER, but given this value to the SERIAL NUMBER STRING, why? How can I set those model number string? [/quote]

That looks like a bug in the GLS example actually.

ble_srv_ascii_to_utf8(&dis_init.serial_num_str, MODEL_NUMBER);

should have been

ble_srv_ascii_to_utf8(&dis_init.model_num_str, MODEL_NUMBER);

[quote userid="15146" url="~/f/nordic-q-a/87560/characteristic-values-for-device-information-service-dis/366178#366178"]You can set these values as you like. See the specification for the service here: https://www.bluetooth.com/specifications/specs/device-information-service-1-1/[/quote]

How can I get those Manufacturer ID, (The id which I have is not number it is a string and size is too small than required size for the manufacture ID) how can I set it? also confused about Organizational Unique ID, how should I update these two fields?

Also confused from the GLS service that they defined MODEL NUMBER, but given this value to the SERIAL NUMBER STRING, why? How can I set those model number string?

Really interested to learn from you,

Take a look at how it's done in e.g. this example: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/ble_sdk_app_bps.html

[quote userid="111909" url="~/f/nordic-q-a/87560/characteristic-values-for-device-information-service-dis"]Is there any standards in order to create those values? how can I get those values which suitable for my product....(I developed custom board with nRF52840)[/quote]

You can set these values as you like. See the specification for the service here: https://www.bluetooth.com/specifications/specs/device-information-service-1-1/
