I want to solve the problem that the characteristic value is not the set value.

Question

Hello. 
 It is being developed using nrf52832 (S132 v7.0.1, SDK v17.0.0) as a peripheral device. 
 Previously, I inquired about how to add a value to the characteristic with this ticket , the error no longer occurs, I can connect, I can confirm that the value of the characteristic is set, and it is solved safely I was able to do it. 
 However, although no error now occurs, the characteristic value is no longer the set value. 
 I don't know why this is happening. Do you have any advice? 
 Also, I am currently inquiring with this ticket , but I am creating a process to switch the advertised UUID. Isn't this advertisement UUID and service UUID need to be linked? I searched for such a process, but couldn't find it. 
 Best regards.

Hello. 
 As a result of repeated investigations, we were able to solve the problem. 
 The cause is that the setting of "is_value_user" was wrong as described in the code example. Previously, I wasn't using "is_value_user", so it worked fine. 
 The code said ".is_value_user = BLE_GATTS_VLOC_STACK", but ".is_value_user = false" was correct. Now that I've corrected the code, I can read the settings. 
 Best regards.
