Hello all,

I am in the process of integrating libiio into a Mangoh Red WP85 project using the bmi160\_fifo branch from the MangOH repository found [here](https://github.com/mangOH/mangOH/tree/bmi160_fifo). My goal is to read three channels from the accelerometer. I have been following the BufferedImuRead sample provided [here](https://github.com/mangOH/mangOH/blob/bmi160_fifo/samples/BufferedImuRead/bufferedImuReadComponent/main.c) .

After calling `iio_buffer_foreach_sample(sampleBuffer, ImuSampleCallback, NULL);` The callback appears to run for the angular velocity channels but not the Accelerometer channels.

I have disabled the Gyro channels using `iio_channel_disable(gyroXChan);` and placed a logging function inside the callback function (`LE_INFO("Running Callback for %s", iio_channel_get_id(chan));`) Resulting in an output of,

This has been confusing me since I am under the impression that disabled channels `would not` be passed into the call back function and that enabled channels `would` be passed into the callback. Having this said I am very new to libiio and would appreciate any insight.

Thanks in advance for any support!
