Arduino + HC-05 changing module name through AT commands

Hello fellow arduino programmers,

I am currently working on a project where i need to change bluetooth name automatically. Using AT+commands i could change the name, the "at+name?" gives me the new name. the probleme i have is that when i go to my smartphone to check the new name i always find that the bluetooth module name isn't changed, to see the new name i need to disable and re-enable my bluetooth ( on the smartphone ) and try to pair the devices.

is there any method to refresh the name programmatically ?

here is an example of my probleme :

original name : HC-05

-> at+name=myBluetooth1

-> at+name?
<-name=myBluetooth1

but when i check my phone i find that the name of my BT module is still HC-05 unless i disable and enable BT and try to pair devices

Thank you
