⚠️ IDs are randomly generated. Each time you broadcast or connect, the adapter assigns you a new id.
⚠️ Reading broadcasts is a two-step process: First, you send `0x1c`. Then, wait until the adapter retrieves data (games usually wait 1 full second). Lastly, send a `0x1e` and it will return what's described above.
⚠️ Reading broadcasts is a three-step process: First, you send `0x1c` (you will get an ACK instantly), and start waiting until the adapter retrieves data (games usually wait 1 full second). Then, send a `0x1d` and it will return what's described above. Lastly, send a `0x1e` to finish the process (you can ignore what the adapter returns here). If you don't send that last `0x1e`, the next command will fail.
