BM62 using BLE GATT Battery Service Query

Hello,
i am currently working with the BM62 Bluetooth + BLE module.
I want the Bluetooth system to update the value of the BLE GATT battery service and have the information be read via a smart phone. Does the Bluetooth module update this service value automatically or will i need an external microcontroller to write a value to a register? if so which UART command is used to update register values for battery service?
 
Thanks in advance 
Ali :)

    Update:
     
    I have found the command "update characteristic" in the audio Uart command word file. I have successfully managed to change the value of GATT battery service value and can read this value on a smart phone. This was done by sending a serial command from an external microcontroller to BM62 via serial. However, is there anyway for this value to auto-update without the use of a external microcontroller? i have looked over the UI tools and can enable battery detect however this does not change the GATT battery service value.
