Gave up fairly quickly on using linux bt stack as it's... Not fun.
Instead I have a ESP32 dongle style board [0] connected with usb to my computer, it present itself as BT HID device to the iPad and communicate with the computer via serial.
Still wip, but overall it works for my main use case(skipping songs & managing volume).
My driving instructor had short pieces of colored tape on the beams between the windshield and side windows.
He would say to people with such problem "turn in the next left blue" every time.
So when they got to their test and and the tester will say to them "turn in the next right" their brain will add a "red" and they will look it up in the car and find it on the right beam.
I'm interested in the about the phrasing "in the next left/right."
Are you located in the US?
I moved from the mid-west to NYC and learned a fun regional language difference about waiting with others: Those from the NYC area say that they are "standing on line" whereas I had grown up saying "standing in line."
