不知您是否参考过文档 Measuring CC13xx and CC26xx current consumption?

Figure 28. Connectable Advertising Event, Capture
Figure 32. Current Consumption versus Time During a Single Connection Event
但是连接上蓝牙后,功耗一下子升到了300多ua
是连接时还是连接后的功耗?若是连接后的话,那连接后数据交互是否比较频繁?
请问您是否有使用TI的例程进行测试,如 simplelink_cc2640r2_sdk \examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral?
功耗大约是多少?另外您是使用开发板还是自制板?
以下是一些测量数据,您可以看一下

一般来说,连接间隔越短,功耗越大
