I'm using an IMU sensor and transferring data over Bluetooth to Android device. The data sampling at 400hz, and I'm sending 6 packets per connection, each packet 20bytes. Connection interval 12ms. In the first 5 seconds, the frequency that I'm receiving data is around 130hz, after it goes up to 400hz like it's supposed to. I'm not sure why this is happening, can someone help, please.
