Hi Sunil,

Right-click your project and select Edit Options, Select Preprocessor and Add the definition to the Preprocessor Definitions. ( "MPU9255", "MPU9150", or "MPU60x0".)

HI,

I am using same github library. instead of keil i want to work in segger. but there is no SES file for the MPU library is there any SES file available..?

and also i am trying to alternate " ble_app_uart_pca10040_s132 " segger solution to work in this MPU library which is SDK 15.2.

for that i also got the error #error "No MPU defined. Please define MPU in Target Options C/C++ Defines"

and more error like

It will be printed over the UART. Are you using a nRF52832-DK? If yes, then you should be able to see the printed data using a terminal program, such as Termite. You can download Termite from this link.

hi,

try that example it will work. i have done this for nrf52840 before 2 months itself. they had released for nrf52832 and nrf52840 now. so no need to make any changes it will work fine

Hi,

I am with the first example now, but I do not get any datas yet. I do not know where it prints the values. So I am gonna program the next example nrf5-ble-mpu-simple.

hi,

in that github file take this example nrf5-ble-mpu-simple. this one will work

hi,

connect the scl and sda pin correctly i think for nrf52832 dk it is the pin no 3 and 4. after interfacing the mpu module to your dk load the program. check the output in uart (termite) or through nrf connect app. it is worked successfully for me in nrf52840.

check whether did you called

ble_mpu_on_ble_evt(&m_mpu, p_ble_evt);

inside the

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)

function

Hi,

I am working with SDK 14.2 and I do not get an error but I do not receive the values of MPU6050

hi,

in which sdk did you ported this example. what error did you get
