View dependencies of ipk files

Embedded Linux platforms frequently use .ipk package files. I have had a need to install specific packages (usually from a Yocto build) during development and testing. It is helpful to know all the dependencies of a package in advance, making it easier to copy all the needed packages to the test environment at one time. Here is how to view dependencies of ipk files.

tl;dr

ar p <file>.ipk control.tar.gz | tar Oxz | grep Depends

Example:

ar p qtdeclarative_5.11.3+git0+e3c0bb7811-r0_armv7at2hf-neon.ipk control.tar.gz | tar Oxz | grep Depends

Results in:

Depends: libc6 (>= 2.28), libgcc1 (>= 8.2.0), libstdc++6 (>= 8.2.0), qtbase (>= 5.11.3+git0+08de243eaa)

BeagleBone Black Wireless – Initial setup and wifi connect

The official BeagleBone Black Getting Started guide isn’t very helpful in connecting the wireless version of the BeagleBone Black (BBBW) to a wireless network. This is what worked for me.
