Hello everybody,
i succeeded to get the output from BME280 and MPU6060 sensors 
I need to merge them together 

Kindly, I need help to Setup prj.conf file

Thanks & Regards

Test the following sample. I added a work queue, such that you can offload the sensor reading when the button is pressed

Get the sensor data from the functions get_mpu6050_data_work_fn and get_bme280_data_data_work_work_fn. (run the sensor_sample_fetch and sensor_channel_get functions inside work queue functions).

Here is the changes I applied

Thank u Simon,
you help was really appreciated 
and i succeeded to display thanks to added the work queue 
here's a capture from my final result
