cc2541 peripheral as broadcaster (using serial interface)

Other Parts Discussed in Thread: CC2541

hi all,

I already interface cc2541 & msp430 using following link successfully.

http://processors.wiki.ti.com/index.php/SimpleBLEPeripheral_SerialInterface. 

Now, i want to broadcast data whatever is  received by received packet from msp430. packet structure is like

77 01 04 61 62 63 64

where,

77 - serial identifier

01 - opcode for advertisement (serialinterface.h) (APP_CMD_ADVERTISE)

04 - data length

61 62 63 64 - a b c d //my data.

 i want to broadcast (only) my data without connecting (i.e.only advertising) 

1) what changes should i made in serialinterface.c/h files ?

2) how can i add my data in static uint8 scanRspData[ ] (instead of Simple BLE Peripheral )

3)there is any command in code to start broadcasting ?

    Hello. You can do this by performing non-connectable advertising and updating the advertising / scan response data as desired. This functionality can all be configured through the GAP_SetParamValue() command with the following parameters (from peripheral.):

      - GAPROLE_SCAN_RSP_DATA

      - GAPROLE_ADVERT_DATA

    In order to advertise non-connectably, you may need to modify the GAPRole (peripheral.c).  There is an example of this occurring in the current peripheral.c:

    if ( events & START_ADVERTISING_EVT )
  {
    if ( gapRole_AdvEnabled )
    {
      gapAdvertisingParams_t params;

      // Setup advertisement parameters
      if ( gapRole_state == GAPROLE_CONNECTED )
      {
        // While in a connection, we can only advertise non-connectable undirected.
        params.eventType = GAP_ADTYPE_ADV_NONCONN_IND;
      }
