How can I see some hidden log on Thingy:52 debug?

Hi Martin. Sorry for waiting.

I have followed exactly the steps you posted and that didn't work. Maybe the problem is with my terminal or my linux (linux mint 19).

Thank you anyway,

Manuel Montenegro

Hi Manuel,

I just downloaded a fresh copy of the thingy SDK.

1. Enabled nrf_log and sat the Log level to 4.

2. Compiled and flashed this application, and connected (BLE) to the Thingy with nrf connect mobile.

3. Turned on the "Thingy Raw Data Characteristic" in the motion service and got out this from the RTT log:

Thank you for your answer, Martin.

That works, but not completely.

Now, I can see all the DEBUG logs, but I think there are some kind of error (maybe a bug?) with Accelerometer, Gyroscope and Magnetometer logs.

This is the log I can get. How you can see, the value field is empty:

m_motion      :DEBUG:DRV_MOTION_EVT_RAW:
m_motion      :DEBUG: accel.x [G's] = :
m_motion      :DEBUG: accel.y [G's] = :
m_motion      :DEBUG: accel.z [G's] = :
m_motion      :DEBUG: gyro.x [deg/s] = :
m_motion      :DEBUG: gyro.y [deg/s] = :
m_motion      :DEBUG: gyro.z [deg/s] = :
m_motion      :DEBUG: mag.x [uT] = :
m_motion      :DEBUG: mag.y [uT] = :
m_motion      :DEBUG: mag.z [uT] = :

How ever, with other sensors I can get the values:

m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 353
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 1
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 8
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 11
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 14
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 10
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 15
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 20
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 28
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 36
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 43
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 48
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 52
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 58
m_motion      :DEBUG:DRV_MOTION_EVT_HEADING [deg]:  h: 63

Any idea about what is happening?

Manuel Montenegro.

Hi Manuel,

Add this in sdk_config.h.

#define NRF_LOG_ENABLED 1

#define NRF_LOG_DEFAULT_LEVEL 4

Increase the NRF_LOG_DEFAULT_LEVEL to 4 to get out debug messages as you can see in "drv_motion.c":

#if NRF_LOG_ENABLED
    void print_sensor_status(void)
    {
        long acc_bias[NUM_AXES];
        long gyr_bias[NUM_AXES];
        long mag_bias[NUM_AXES];
        int acc_accuracy;
        int gyr_accuracy;
        int mag_accuracy;
        
        inv_get_accel_bias(acc_bias, NULL);
        inv_get_gyro_bias(gyr_bias, NULL);
        inv_get_compass_bias(mag_bias);
        
        acc_accuracy = inv_get_accel_accuracy();
        gyr_accuracy = inv_get_gyro_accuracy();
        mag_accuracy = inv_get_mag_accuracy();
        
        NRF_LOG_DEBUG("Acc bias: ");
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(acc_bias[0]));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(acc_bias[1]));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(acc_bias[2]));
        
        NRF_LOG_DEBUG("Gyr bias: "); 
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(gyr_bias[0]));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(gyr_bias[1]));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(gyr_bias[2]));

        NRF_LOG_DEBUG("Mag bias: ");
        NRF_LOG_DEBUG("X: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(mag_bias[0]/(2^16)));
        NRF_LOG_DEBUG("Y: "NRF_LOG_FLOAT_MARKER" ",     NRF_LOG_FLOAT(mag_bias[1]/(2^16)));
        NRF_LOG_DEBUG("Z: "NRF_LOG_FLOAT_MARKER" \r\n", NRF_LOG_FLOAT(mag_bias[2]/(2^16)));

        NRF_LOG_DEBUG("Accur: Acc: %d, gyr: %d, mag: %d \r\n", acc_accuracy, gyr_accuracy, mag_accuracy);
    }
#endif
