How to modify the Firmware Revision String

[SunHuang]

Hi,

This string is defined by "CONFIG_BT_DIS_FW_REV_STR". Is there any API that can modify it?

Currently version management is done through VERSION files, but its display format is "1.2.3+4".

I want to change "CONFIG_BT_DIS_FW_REV_STR" to "1.23".

Is there any suggestion?

Hi,

Try to set 

VERSION_MAJOR = 1

VERSION_MINOR =23

Kind regards,
Andreas

Hi,

It's format is not what I expected because its default format is "0.0.0+0".

The format I want is "0.00"(VERSION_MAJOR.VERSION_MINOR).

So I hope to modify the BLE information through API.

Hmm, By omitting PATCHLEVEL, VERSION_TWEAK, and EXTRAVERSION fields, you should observe the version format "major_version.minor_version".

But note that some uses of version number (for instance MCUboot or OTA updates), the version might be repsented internally as "1.23.0+0" due to how MCUboot expects the versioning to be formatted. However, for display purposes and in many API calls, it will appear as "1.23".

Kind regards,
Andreas

Hi,

So I hope to modify the content of "CONFIG_BT_DIS_FW_REV_STR" by writing a string.

Can you tell me what is the API to modify BLE GATT?

Could you clarify if you mean "to modify the config during runtime" or to "modify it as a string before building"?

I'm not sure what you're referring to, but here is the API for bt_gatt: https://docs.nordicsemi.com/bundle/nrf-apis-latest/page/group_bt_gattp.html 

Kind regards,
