Yes, the 16-bit UUID is inserted as 12-13 octet in the 128-bit UUID base. I only made this example for Keil, GCC and Segger Embedded Studio, but you should be able to copy the custom service code into the IAR project of the ble_app_template project. I have attached the .hex file generated using SES.

Okay, thank you. So the software will still use a 16 bit UUID and this can be traced to a 128 bit UUID using the UUID type.

Is there an IAR project for this example by any chance?

Even .hex would be appreciated.

Yes, it is possible to configure the Service and its characteristics to use two different UUID bases. Please see the attached example, extract it to the nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ folder
