Characteristic values for Device Information Service (DIS)?

[Sreejith Sundh]

Hallo,

As I am developing a new product (peripheral acceleration sensor device) I would like to update the DIS service data with the following characteristics, Manufacturer Name string, Model Number String, Serial Number String, Hardware and Firmware revision string and System ID....How can I update those characteristics? 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)

Thanks for your time and effort.

Thanks and Regards,

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

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/

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,

Thanks and Regards,

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.

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);
