The "I have NO IDEA" 0xE5 command seems to be a handshake packet with a passphrase based on the serial number of the device. Sadly, we can't actually read the serial number from the device until after this handshake as successfully completed, which makes it a bit of a chicken-and-egg problem from a communication standpoint. However, the serial number is also exposed in the bluetooth name that the device advertizes, which is the reason for the newly added "dc_iostream_get_name()" function - so that whoever set up the IO for us can give us the name. Annoying, yes, but less annoying than "I have NO IDEA". Thanks to Janice McLaughlin for pointing out the logic of this magic handshake, which is apparently also the case for the Aqualung i300C. This also simplifies the command sequence handling: if you use oceanic_atom2_ble_transfer() and ask for an answer (even if the answer size is zero, and only the ACK is returned), the BLE transfer code will handle the sequence number on its own. Only if you send a packet without expecting an answer at all do you need to manage the sequence number manually. This is mainly used for oceanic_atom2_device_write(), although I suspect that code gets an ACK and could use a zero answer size too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
