Project day 24

No, unless you modify the Central project (from that throughput example) to connect and read the desired GATT notification from your Peripheral.

For getting the basic example project working, you will need the attribute to be the same UUID and size/variable type for the example project to correctly read and interpret the values. like SrikanthD_56 stated, you would need to change the central to connect, and then accept notification values for use with the throughput measuring.
