This script is great! And shows me some advanced shell-fu.

Though there's an issue with it when you have multiple pairs of Headphone/AirPods that were at one point paired to your system.

For me, this line returns multiple mac addresses, all of ones previously connected along with the actually connected one:

MAC_ADDR=$(grep -b2 "Minor Type: Headphones"<<<"${SYS_PROFILE}"|awk '/Address/{print $3}')

That means that later when $(awk -v pat="${info}" '$0~pat{gsub (";",""); print $3 }'<<<"${BT_DATA}") is called, it somehow fetches old battery data for every pair of old headphones. And my output ends up looking like this. Only one of those battery values matches my currently in-use airpods, the rest must be old cached battery values...?

My hacky fixes is just to limit the mac_addr fetch to the specific pair of airpods I actually use like this:

MAC_ADDR=$(grep -b2 "Minor Type: Headphones"<<<"${SYS_PROFILE}"|awk '/Address/{print $3}' | grep "<my airpods mac address>")

(I easily lookup the mac address for my airpods using the amazing BluetoothConnector util.)

Instead of my hacky one-off solution, here's a more generalized solution. Though I'm sure there's a more elegant terser way of doing it.

Just replace the CONNECTED=$(...) line with this:

CONNECTED=""
for m in ${MAC_ADDR} ; do 
  grep -ia6 "${m}"<<<"${SYS_PROFILE}"|awk '/Connected: Yes/{print 1}' | grep 1 && MAC_ADDR="$m" && CONNECTED=1 && break ;
done

That just checks if each mac address is connected, and when it finds a connected one, redefines MAC_ADDR to just the value of the connected pair.

Edit: Put this in a fork available here: https://gist.github.com/varenc/6300183cc2be8a4d4a1dd941eb2f5766

Running the script returns "Not connected", although my Airpods Max are connected. Is this no longer working?

Same problem with AirPods 2

The script here doesn't work for me, but this command does:

system_profiler SPBluetoothDataType 2>/dev/null | grep -o "Left Battery Level: [0-9]*%" | grep -o "[0-9]*%"
