My project with an Advertising interval of 700ms, the connection is too slow, long time 100MS Advertising , power consumption is too big. If you can use 700ms, host and connection, adjust to 100ms to speed up connection.

Hi zhangtinglu8888,
I am not sure i understand the question, i suppose that when you set the advertising interval in 700ms the connection procedure takes more time than when the device is advertising in 100 ms. The reason for that is because in order to connect to a device you need at least two advertising events. One is for the scanner to track the device on the air, as soon as the scanner "sees" the device it will send a connection request, in order for the peripheral to get the connection request it is required to send one more advertising event in order to receive the connection request. So its quite reasonable for the 700 ms advertising to take more time to connect against the 100 ms advertising procedure. If you think that 100ms consumes more power than your device's specs you will have to find a proper value by selecting a value among the 100ms and 700ms in order to balance the power consumption with the connection establishment time.
