Need help to read the Firmware Revision String from a peripheral on my Central

Remember that centrals historically has been mobile phones. The small devices are typically the peripherals.

The ble_dis_c folder containing the .c/.h files that are present in the later SDKs are not present in SDK12.3.0, so I don't think there are any examples on that in SDK 12.3.0, unfortunately. However there are many examples with ble_xx_c. Did you run into any issues while backporting the ble_dis_c.c/h to SDK12.3.0? It is a bit hard to tell just by looking at your code.

Sorry i don’t get it

There is a huge difference in SDK15.x to SDK12.3 in case of Soft device.

it cannot be that I am the first to read the device information from a peripheral with SDK12.

There must be an example somewhere

My code so far:

devzone.nordicsemi.com/.../2330.ble_5F00_dis_5F00_c.c devzone.nordicsemi.com/.../3823.ble_5F00_dis_5F00_c.h devzone.nordicsemi.com/.../0383.main.c

sorry. I forgot that you wrote SDK12.3.0 when I investigated your question.

You are correct. There is no implementation of ble_dis_c in SDK12.3.0.

You can try to copy these parts from a later SDK, which contains the ble_dis_c (Device Information Service_ Central) service.

Look at how the files and libraries are used in sdk_15.0.0, and see if you can backport it to SDK12.3.0. The most important part is that you need to do the service discovery for the DIS Service UUID, and then, after it is discovered (discovery complete), you need to read the FW version.

Sorry there is no \examples\ble_central\ble_app_rscs_c in the SDK 12.3

There is one under experimental but there i cant find a BLE_DIS_C_FW_REV

can i use parts of the SDK 15.X in my SDK 12.3 projekt ?

Hello,

I suggest you check out the example:

SKD\examples\ble_central\ble_app_rscs_c, which has a central implementation of the DIS (device information service).

It has support for reading out the BLE_DIS_C_FW_REV.

Best regards,

Edvin
