When I start app redSensorToCloud, all sensors don’t send the value to the Cloud. So, I would like to verify sensors in Red mango such as pressure, light sensor one by one to make sure that the sensor is still working. Any ideas?

are you using WP76? You can have a look on this thread: [image] MangOH Red Not Transmitting mangOH Red How do I check the sensor driver and app log?

It is WP8548. Some sensor can transmit sometimes. Really have no idea

have you compared the logread to debug?

This is what I got from logread -f Oct 8 14:08:04 swi-mdm9x15 user.err Legato: =ERR= | redSensor[1080]/position T=main | position.c Sample() 50 | Failed to read sensor (LE_OUT_OF_RANGE). Oct 8 21:08:04 swi-mdm9x15 user.err kernel: [ 860.181443] qup_i2c qup_i2c.0: QUP: I2C status flags :0x1300c…

You can try to see the value of the following and see if the sensor is working fine. /sys/bus/i2c/devices/0-0068/iio:device0/in_accel_x_raw

-sh: /sys/bus/i2c/devices/0-0068/iio:device0/in_accel_x_raw: Permission denied

You should use “cat /sys/bus/i2c/devices/0-0068/iio:device0/in_accel_x_raw”

it replies in some values. however, do you know the address for light sensor, pressure sensor…?

root@swi-mdm9x15:~# ls /sys/bus/i2c/devices/0-0068/iio:device0 buffer in_anglvel_sampling_frequency in_temp_scale dev in_anglvel_sampling_frequency_available name in_accel_sampling_frequency in_anglve…

This is for pressure sensor /sys/bus/i2c/devices/0-0076/iio:device1/in_pressure_input
