Hello All,
I am working on nrf52810 board
Using sdk 14.2
I am trying to modify some bytes of advertising packet .
I am referring the previous post as link given below
https://devzone.nordicsemi.com/f/nordic-q-a/8854/fully-custom-advertisement-data
I have modified the advertising init function as per the above link.
But i am getting warning like incompatible type.
how to solve this issue with proper advertising .
What modification is required in the code..?
Please reply if anyone having solution for this issue.
I am attaching the my main.c file please verify and let me know any changes required.
