VOXL Inspect Battery

This tool subscribes to the /run/mpa/mavlink_sys_status pipe published by voxl-vision-hub which provides a copy of all SYS_STATUS mavlink messages received from a PX4 flight controller. Among other things, this packet contains battery status information which can be viewed here.

Also note that voxl-portal subscribes to the same pipe and also shows battery percentage in the top right corner of the webpage.

Arguments

voxl2:/$ voxl-inspect-battery --help

Tool to print battery data from autopilot to the screen for inspection.
If no data comes through then either:
    1. the voxl-vision-hub service isn't running
    2. autopilot isn't connected

-h, --help              print this help message
-n, --newline           print newline between each sample

Use

voxl2:/$ voxl-inspect-battery

 Voltage |  Charge | Current |  Power  |
  12.22V |    89%  |   0.49A |   5.99W |

Troubleshooting

If no data is displayed, then either voxl-vision-hub is not running or PX4 is not connected or operating. Individual fields print N/A when the autopilot reports invalid values.
