title: Connecting ESP32 to GameSir T4 pro controller via Bluetooth
body: <p>I try to connect a &quot;GameSir T4 pro&quot; controller (<a href="https://www.gamesir.hk/products/gamesir-t4-pro" rel="nofollow noreferrer">https://www.gamesir.hk/products/gamesir-t4-pro</a>)
  to ESP32 using Bluetooth.</p>
  <p>Since i already have it and it supports Bluetooth connection, it was my first choice...
  using several servos i want to build a tiny crane, controlled by the Gamesir controller.</p>
  <p>does anyone here have some experience with programming the controller?
  any known guide or repository to a similar project?</p>
  <p>im searching for a few days now and no progress so far..</p>
  <p>Much appreciation for all the helper and advisers!:)</p>
