Trouble to read, write and activate notification

[DavidC]

Hello comunnity,

I am trying to read, write and activite notification from my server using a central device. The problem is when I use more than 2 times, I got an error of NRF_ERROR_INVALID_DATA But When i do it separetly the code works.

I attached a picture of my output, First I read the Hz, then I write a new HZ, after this I read again the HZ and the end I activate some notifications. Eventhought, after each sentence I put a delay and it's having the same problem

Why is this behavior?

Regards, David Caraveo
