tx_samples_from_file only works with channel 0 #706

Closed joelkeeling closed 7 months ago

joelkeeling commented 1 year ago

Issue Description

The example program tx_samples_from_file does not properly handle the channel argument

Setup Details

Run the example program with the '--channel' argument set to anything but '0'

Expected Behavior

The transmission would be correctly configured for the specified channel

Actual Behaviour

Configuration settings always get written to channel 0

Steps to reproduce the problem

I will instead describe the fix to the problem: Many calls throughout the example rely on function "default arguments" to set the channel. In most cases the default is channel '0'. Calls that could, but don't specify the channel are: set_tx_rate, set_tx_freq, set_tx_gain, set_tx_bandwidth set_tx_antenna

Additional Information

We have corrected this issue on our local system. If time permits, I hope to provide a small Pull Request to correct the issue.
