CC2650 要发送超过20字节数据的注意事项

build_config.opt里面的配置应该选哪一项?

/* BLE v4.2 Features */
/* -DBLE_V42_FEATURES=SECURE_CONNS_CFG+PRIVACY_1_2_CFG+EXT_DATA_LEN_CFG */
/* -DBLE_V42_FEATURES=SECURE_CONNS_CFG+PRIVACY_1_2_CFG */
/* -DBLE_V42_FEATURES=PRIVACY_1_2_CFG+EXT_DATA_LEN_CFG */
/* -DBLE_V42_FEATURES=SECURE_CONNS_CFG+EXT_DATA_LEN_CFG */
/* -DBLE_V42_FEATURES=SECURE_CONNS_CFG */
/* -DBLE_V42_FEATURES=PRIVACY_1_2_CFG */
/* -DBLE_V42_FEATURES=EXT_DATA_LEN_CFG */

目前选择的是:

 -DBLE_V42_FEATURES=SECURE_CONNS_CFG 

即是把这一行的注释去掉
