what is the market share of Bluetooth Classic iPhones in 2023 now ?

i have been making ios app that communicate with ESP32 using bluetooth classic.

but this is very difficult to develop,

because i can't find any Bluetooth scan app for test that can communicate with ESP32 until now,

moreover, i can't find any sample code for Bluetooth Classic Communication .

my client want me to make ios app using Bluetooth classic

because of compatiblity, in other words, still, users using Bluetooth Classic iphone are used lots of users more than Bluetooth Low energy.

so i doubt this assumption is right.

if i make a bluetooth low energy app, can it be a trouble ?

I believe that the last iPhone without Bluetooth Low Energy was the iPhone 4, which launched in 2010. Its current market share is zero.
