Good morning
Doing the BLE fundamentals course and cant seem to build lesson 4 ex 3. Have picked up this thread BLE Fundamentals lesson 4 exercise 3 failure to build - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com) with no solution.
using the latest tool chain, nrf52840DK 2.02.
The errors in the function below im receiving are

I have tried to build the solution as well with the same outcome
Thanks in advance for any assistance.
