(Edit) It is difficult to output the sensor value through the ble_app_uart.

[schosdas]

Hello

I am using SDK v17 and nRF52DK board (PCA10040) and testing mpu6050 sensor.

I want to print out the sensor value through the app through ble_app_uart. 

Before sending the sensor values through the app, I would like to test the output at the terminal.
However, there is a problem merging to the ble_app_uart code.

Bluetooth connections work well, but debugging will cause 'NRF_BREKPOINT_COND;'error. Printed at 'err_code = app_mpu_read_accel (& accel_values)

I attached the project because there may be a problem with other parts.

The mpu6050 was placed in the \nRF5_SDK_17.0.0_9d13099\examples path.

Can you tell me the problem?
Thank you in advance.
