https://devzone.nordicsemi.com/f/nordic-q-a/13539/arduino-accel-gyro-nrf8001-hid-mouseHi, For the past few weeks I&#39;ve been trying to make a small device that would simulate a mouse with Arduino and MPU6050 accelerator + gyroscope sensor. I wanted the device to run on batteries and the communication to be done via Bluetooth LE, so Ien-USTelligent Community 13Tue, 03 May 2016 08:31:57 GMThttps://devzone.nordicsemi.com/thread/51665?ContentTypeID=1Tue, 03 May 2016 08:31:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:55162138-5835-4dbd-bf1b-cc9cd1eea8e6vgUtilis<p>Hello and thank you for your answer. The minimal connection interval was 7.5 ms and the maximum was 24 ms. I changed it to 7.5 ms - 12 ms and it certainly works way smoother, its just that it is not what I expected because vertical movement works just as expected but horizontal movement is jumpy, but that I guess is due to my Arduino setup rather than the nRF8001 itself, so I am marking your answer as correct.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/51664?ContentTypeID=1Mon, 02 May 2016 09:12:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:026342b3-18db-44ba-b0b3-b07771e9d673run_ar<p>What is your connection interval in this case? I would recommend a connection interval in the 7.5 - 15ms range. You can request faster interval from the master using lib_aci_change_timing_GAP_PPCP or <a href="https://github.com/NordicSemiconductor/ble-sdk-arduino/blob/master/libraries/BLE/lib_aci.cpp#L449">lib_aci_change_timing</a>.</p><div style="clear:both;"></div>
