Hello,
I am working on a project using the STM32WB55 and its BLE stack. I am trying to implement a custom service with more than three characteristics. However, when I add a fourth characteristic, the function aci_gatt_add_char returns the error code 0x98.
Interestingly, if I add two more services each with two characteristics (i.e., a total of 3+2+2 = 7 characteristics), there are no issues. The problem occurs only when a single service contains more than 3 characteristics.
I followed the Heart Rate Monitor example.
Thank you for any help.

Have you looked-up what that code means?

I tried, but I couldn't find out what it means.
