4.6.7

Evt_Blue_Gatt_Read_Multi_Permit_Req

This event is given to the application when a read multiple request or read by type request is

received by the server from the client. This event will be given to the application only if the

event bit for this event generation is set when the characteristic was added.

On receiving this event, the application can update the values of the handles if it desires and

when done, it has to send the Aci_Gatt_Allow_Read command to indicate to the stack that it

can send the response to the client.
