How to update data in Softdevice Buffer after sd_ble_gatts_hvx call ?

Question

Hi, 
 After sd_ble_gatts_hvx() call, is it possible to change or delete value in softdevice buffer before a connection event ? 
 Thanks by advance for your help 
 Best regards,

Unfortunately no. Once the buffer is given to softdevice, then you cannot edit the contents. This would also be logically wrong to do it, as softdevice will not be able to guarantee you a safe time between hvx and your application wanting to edit it before it is sent by the RADIO.
