Aci_Gatt_Allow_Read

Description:

The application has to send this command when it receives the

Evt_Blue_Gatt_Read_Permit_Req or Evt_Blue_Gatt_Read_Multi_Permit_Req. This

command indicates to the stack that the response can be sent to the client. So if the

application wishes to update any of the attributes before they are read by the client, it has to

update the characteristic values using the Aci_Gatt_Update_Charac_Value and then give

this command. The application should perform the required operations within 30 seconds.

Otherwise the GATT procedure will be timeout.

Event(s) generated:

A command complete event is generated when this command is processed.
