本文介绍了CC2640R2F在BLE开发中的GAP配置，包括设备角色配置命令、广播数据类型以及广播发现模式。详细讲述了如何在peripheral_broadcaster.c中调用API进行设置和获取操作，并提到了GAPROLE_PROFILEROLE、GAP_ADTYPE_FLAGS和GAP_ADTYPE_APPEARANCE等关键概念。

GAP

generic access profile

以下命令都是在广播过程应用的命令

C:\ti\simplelink_cc2640r2_sdk_2_40_00_32\source\ti\blestack\profiles\roles\peripheral_broadcaster.c

调用API-设置

bStatus_t GAPRole_SetParameter(uint16_t param, uint8_t len, void *pValue)

调用API-获取

bStatus_t GAPRole_GetParameter( uint16 param, void *pValue )

举例：设置广播数据，注意多个参数时的写法

// Advertisement data (max size = 31 bytes, though this is
// best kept short to conserve power while advertising)
static uint8_t advertData[] =
{
  // Flags: this field sets the device to use general discoverable
  // mode (advertises indefinitely) instead of general
  // discoverable mode (advertise for 30 seconds at a time)
  0x02,   // length of this data
  GAP_ADTYPE_FLAGS,
  DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

  0x05,
  GAP_ADTYPE_MANUFACTURER_SPECIFIC,
  0x55,
  0x55,
  0x55,
  0x55,
  0x55,
  // service UUID, to notify central devices what services are included
  // in this peripheral
  0x03,   // length of this data
  GAP_ADTYPE_16BIT_MORE,      // some of the UUID's, but not all
  LO_UINT16(SIMPLEPROFILE_SERV_UUID),
  HI_UINT16(SIMPLEPROFILE_SERV_UUID)
};
GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(advertData), advertData);

设备角色配置命令

C:\ti\simplelink_cc2640r2_sdk_2_40_00_32\source\ti\blestack\profiles\roles\cc26xx\peripheral.h

命令	说明
GAPROLE_PROFILEROLE	此参数将返回设备角色类型(只读)，4种
GAPROLE_IRK	身份解析密钥（读/写）大小为uint8_t [KEYLEN]。
GAPROLE_SRK	签名解析密钥（读/写）
GAPROLE_SIGNCOUNTER	标志计数器（读/写）
GAPROLE_BD_ADDR
