CC2340R5: 发射功率问题
最新的SDK simplelink_lowpower_f3_sdk_7_20_01_10可以设置发射功率了吗？ 调用HCI_EXT_SetTxPowerCmd(); 还是不起作用？
您好，
1.最新版的SDK f3_sdk_7_20可以设置发射频率了
是通过HCI_EXT_SetTxPowerCmd(HCI_EXT_TX_POWER_0_DBM);
2.您可以将您的代码截图，以及返回值状态放上来看一下吗？这更有利于解决问题
3.调用HCI_EXT_SetTxPowerCmd(HCI_EXT_TX_POWER_0_DBM);
注：
请检查您的传参是否正确
在用此函数之前必须先初始化蓝牙协议栈
以下是此函数的描述，为您附上API的链接
