+## Bluetooth DID (Device Identification) Hook
+
+Turns out, if you change the manufacturerid to that of Apple, you get access to several special features!
+
+### Multi-device Connectivity
+
+Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.
+
+### Accessibility Settings and Hearing Aid
+
+Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
+
+The hearing aid feature can now also be used. Currently it can only be used to adjust the settings, not actually take a hearing test because it requires much more precision. It is much better to use an already available audiogram result.

- * @XZ_OPTIONS_ERROR:       This implementation doesn't support the requested

- *                          that the header CRC32 matches, but the header
- *                          itself specifies something that we don't support.
- * @XZ_DATA_ERROR:          Compressed data is corrupt.
- * @XZ_BUF_ERROR:           Cannot make any progress. Details are slightly
- *                          different between multi-call and single-call
- *                          mode; more information below.
- *
- * In multi-call mode, XZ_BUF_ERROR is returned when two consecutive calls
- * to XZ code cannot consume any input and cannot produce any new output.
- * This happens when there is no new input available, or the output buffer
- * is full while at least one output byte is still pending. Assuming your
- * code is not buggy, you can get this error only when decoding a compressed
- * stream that is truncated or otherwise corrupt.
- *
- * In single-call mode, XZ_BUF_ERROR is returned only when the output buffer
- * is too small or the compressed input is corrupt in a way that makes the
- * decoder produce more output than the caller expected. When it is
- * (relatively) clear that the compressed input is truncated, XZ_DATA_ERROR
- * is used instead of XZ_BUF_ERROR.

- * of memory is preallocated for the LZMA2 dictionary. This way there is no
- * risk that xz_dec_run() could run out of memory, since xz_dec_run() will
- * never allocate any memory. Instead, if the preallocated dictionary is too
- * small for decoding the given input stream, xz_dec_run() will return
- * XZ_MEMLIMIT_ERROR. Thus, it is important to know what kind of data will be
- * decoded to avoid allocating excessive amount of memory for the dictionary.
- *
- * Multi-call mode with dynamically allocated dictionary (XZ_DYNALLOC):
- * dict_max specifies the maximum allowed dictionary size that xz_dec_run()
- * may allocate once it has parsed the dictionary size from the stream
- * headers. This way excessive allocations can be avoided while still
- * limiting the maximum memory usage to a sane value to prevent running the
- * system out of memory when decompressing streams from untrusted sources.
- *
- * On success, xz_dec_init() returns a pointer to struct xz_dec, which is
- * ready to be used with xz_dec_run(). If memory allocation fails,

- * xz_dec_run() is a wrapper for dec_main() to handle some special cases in

- *
- * In multi-call mode, we must return XZ_BUF_ERROR when it seems clear that we
- * are not going to make any progress anymore. This is to prevent the caller
- * from calling us infinitely when the input file is truncated or otherwise
- * corrupt. Since zlib-style API allows that the caller fills the input buffer
- * only when the decoder doesn't produce any new output, we have to be careful
- * to avoid returning XZ_BUF_ERROR too easily: XZ_BUF_ERROR is returned only
- * after the second consecutive call to xz_dec_run() that makes no progress.
- *
- * In single-call mode, if we couldn't decode everything and no error
- * occurred, either the input is truncated or the output buffer is too small.
- * Since we know that the last input byte never produces any output, we know
- * that if all the input was consumed and decoding wasn't finished, the file
- * must be corrupt. Otherwise the output buffer has to be too small or the
- * file is corrupt in a way that decoding it produces too big output.
- *
- * If single-call decoding fails, we reset b->in_pos and b->out_pos back to
- * their original values. This is because with some filter chains there won't
- * be any valid uncompressed data in the output buffer unless the decoding
- * actually succeeds (that's the price to pay of using the output buffer as
