Hi, I want to make a simple application with an STM32WB5MMG that exposes a characteristic which I can read. I created the service and the characteristic, and I enabled the CHAR_PROP_READ property. In custom_app.c, I then use Custom_STM_App_Update_Char to update the value under the CUSTOM_STM_FW_VER_READ_EVT case branch. However, I can't read the correct value—it always returns 0.
I also tried enabling the GATT_NOTIFY_READ_REQ_AND_WAIT_FOR_APPL_RESP property, but from the debugger, I see that it doesn't even enter the void Custom_STM_App_Notification(Custom_STM_App_Notification_evt_t *pNotification) function.
Can someone help me?
Thanks.
