Hello, i solved the problem.  
My english isn’t so good, sorry, i am from Argentina.  
The thing is that you are using a Characteristic on de BLE that isn’t READ. Most of the BLE modules have a Characteristic that NOTIFY when the register change.  
I use a ESP32 with Arduino  
Fist, i was having the error “operation was rejected” because I created a Characteristic as NOTIFY  
I make it work when i defined the Characteristic as READ.  
i hope it helps you because i lost several hours with this.
