I hope this function can be executed regularly, for example, every five seconds. What should I do?

thank you!

Hi,

Use a timer to call this function. use 'TMR_StartLowPowerTimer' to start the timer.

Have a great day,
TIC

Are you talking about the two functions in the picture ? 

After connecting to the mobile phone, these two functions do not seem to be executed, and the data is not received on the mobile phone.

Hi,

No. I mean that you need define your own timer. Put that function as callback to your timer.

Have a great day,

Hello, I don't understand very clearly. Can you give me a simple example?

Hi,

代码里面有个功能就是定时器功能，它可以定时发消息。你可以看一下private_profile_server和client的例程。这个是计算ble的传输速度的，他就是用的定时器。这个定时器首先你要静态定义一个变量，然后使用TMR_AllocateTimer来给变量分配一个定时器ID，然后使用TMR_StartLowPowerTimer来启动定时器，其中第四个参数就是你要执行的回调函数，你要执行什么函数就把函数地址放进去。第二个参数，你可以选择这个定时器是一次性的还是连续的，你想不断发就用gTmrLowPowerIntervalMillisTimer_c，第三个参数就是时间，你自己设就好了。最后不想用这个定时器就TMR_StopTimer，停掉你的这个定时器。

Have a great day,
TIC
