Adjust Arduino 101 Bluetooth Interval

YWang87 · ‎07-18-2017

Hello!

I am trying to send a file from Arduino 101 to the Android phone via Bluetooth. But I notice that the package interval is around 100 ms when I enable the BLE notification while transfering the data.

Later, I tried to check the ble_client.h library to adjust the default interval parameters as below:

# define DEFAULT_MIN_CONN_INTERVAL MSEC_TO_UNITS(12, UNIT_1_25_MS)

# define DEFAULT_MAX_CONN_INTERVAL MSEC_TO_UNITS(15, UNIT_1_25_MS)

# define MIN_CONN_INTERVAL 0x0006

# define MAX_CONN_INTERVAL 0x0015

I did receive lower interval for BLE broadcasting, but when I start to transmit the data (with BLE notification enabled), it increases to 98ms. Does anyone have any idea about it?

Thanks in advance!
