hi,
go to the link https://devzone.nordicsemi.com/f/nordic-q-a/30832/to-collect-multiple-sensor-values-and-transmit-it-over-bluetooth-using-nrf52840-dk
download the mpu.zip file. i have uploaded that. just extract that go to examples-->peripherals-->ble_app_template. compile it. define mpu 9255 in target menu. define spi.
i have done it for nrf52840 using twi.
if you want it for nrf52832. just correctly connect your mpu9255 in spi pin of your dk. no need to modify anything in the program just load it.
regards
I have interfaced as shown in image attached.There is one more issue,when I try to flash the code into nrf52 dk with this connction,Its shows error as " jlink error could not find core in coresight".I have connected GND of mpu9255 to one of GND on nrf52dk
hi,
so you are using nrf52840. if yes just go to the link and download the file and do the modification as i mentioned. if it is not working just try it with i2c the i2c pin for nrf52840 i have mentioned is 27 scl and 26 sda.

hi,
