蓝牙cc2540可以在不配对的情况下读写特性的值吗？

BLE一般都不配对连接，协议栈里的demo都没有配对限制，android由于系统设置会要求配对，可以通过从机修改 配对模式来跳过：

// Setup the GAP Bond Manager
{
uint32 passkey = 0; // passkey "000000"
uint8 pairMode = GAPBOND_PAIRING_MODE_WAIT_FOR_REQ; //GAPBOND_PAIRING_MODE_NO_PAIRING;
uint8 mitm = TRUE;
uint8 ioCap = GAPBOND_IO_CAP_DISPLAY_ONLY;
uint8 bonding = TRUE;
GAPBondMgr_SetParameter( GAPBOND_DEFAULT_PASSCODE, sizeof ( uint32 ), &passkey );
GAPBondMgr_SetParameter( GAPBOND_PAIRING_MODE, sizeof ( uint8 ), &pairMode );
GAPBondMgr_SetParameter( GAPBOND_MITM_PROTECTION, sizeof ( uint8 ), &mitm );
GAPBondMgr_SetParameter( GAPBOND_IO_CAPABILITIES, sizeof ( uint8 ), &ioCap );
GAPBondMgr_SetParameter( GAPBOND_BONDING_ENABLED, sizeof ( uint8 ), &bonding );
}
