[Menaka_12]

Hi team,

I am using sdk 14.2 ,nrf52840 DK board.

I am getting the following error while running nrf5-mpu-ble-simple code in keil.<error> app: Error 0x000D (13) at line 750 in file: ..\..\..\main.c

Also I changed twi_pins,I also got the same error.

main.rar

Here I have attached the main file.And when I commented this line

((APP_ERROR_CHECK(ret_code); at line 750 and 757 in file main.c,),I am getting no values(<info> app: Accel: 00000, 00000, 00000, 0x0000, 0x0000, 0x0000) in terminal.

Please help me out!

Thanks

Hi, 

Error 13 corresponds to NRF_ERROR_TIMEOUT if the "app_mpu" module uses the NRF error base, see nrf_error.h. I'm not sure what app_mpu_init() does since it's not defined in main.c. Does it perform any i2c transactions? I'd recommend to use a logic analyzer if you have one and check if the there's a address NACK,etc.
