When the EZ-BT WICED Module starts up, it enters the 

APPLICATION_START()

 function. The 

BTM_ENABLED_EVT 

is 

the first stack-generated event after power ON or reset; it indicates that Bluetooth stack initialization is complete. The 
initialization  functions 

application_init

  and 

hello_sensor_applicaiton_init 

functions  are  executed  in  the  

BTM_ENABLED_EVT

 event. These initialization functions call appropriate APIs to initialize the Service Discovery Protocol 

(SDP) database for Bluetooth BR/EDR, initialize the GATT database for BLE, set the advertisement data, set the inquiry 
response data and register appropriate callbacks, initialize the timers, and configure the button and LED based on the 
application requirements. 

Figure 17

 shows the flowchart for system initialization.

Internal Stack 

Processing Loop

 

Before looking at the application initialization routines,  look at 

wiced_bt_cfg.c

. The configuration structure in this file 

allows simple control over advertisement and scan parameters for BLE and inquiry/page scan interval for Bluetooth 
BR/EDR, and some of the profile-specific behavior. In many cases, the SDK provides APIs that allow you to trigger 
behavior with custom settings rather than the values that are set here. However, you can often use these configuration 
values as-is and avoid further complexity in your code. 

The  following  Bluetooth  configuration  parameters  can  be  modified  based  on  application  requirements  by  modifying 
values in 

wiced_bt_cfg.c

 shown in 

Code 14

. 

▪

 

Advertisement and scan settings for BLE  

▪

 

Choice of advertisement channels to be used for BLE  

▪

 

Scan and page interval settings for Bluetooth BR/EDR  

▪

 

Bluetooth Device name 

▪

 

MTU size, etc. 

The 

“spp_custom”  example  described  in  this  guide  does  not  require  any  modifications  to  this  structure  except 

BT_LOCAL_NAME. You can choose to retain the default name as well; for the spp sample application, 

it is “spp”.
