/* new todo file for BTstack */
2009-11-08: Release 0.1
2010-06-20: Release 0.2 - SDP + iOS 4 support
2010-11-2x: Release 0.2 - revsion 973 for WeBe++
- fix regression bug in 0.2-899 that prevented disabling of Apple Bluetooth stack, less crashes
- Startup: send kill signal to BlueTool and BTServer, if necessary
- Connection establishment: don't close baseband during authentication,
- Remote Device DB: automatic link key handling in BTdaemon, provide cached remote names during inquiry
- SDP: use 1000 bytes MTU, fix partial responses, fix an incompatibility with Windows native statck
- Cocoa run_loop: added timeouts, include in libBTstack.dylib build
NEXT:
- figure out how to receive iPhone System Power IONotifications (in BTdaemon) to detect, when phone gets locked
- limit size of /tmp/hci_dump.pklg
- e.g. rm hci_dump.old.pklg, mv hci_dump.pkg->hci_dump.old.pklg
- have a look at External Accessory interface by Apple - it's quite similar
- move RFCOMM code into BTdaemon
- HCI CMD packet is limited to 1024 bytes payload. SDP records could be larger than that. Options:
- provide a way to transfer SDP records in segments
- ignore HCI command lenght on socket connection and directly stream data without buffer
- L2CAP
- segmentation
- Link Key storage in Bluetooth module
- store link keys in Bluetooth module. requires algorithm to evict old one but unclear how to implement that
- extend SpringBoard feedback
- show alerts/messages using SpringBoardAcccess, e.g. Bluetooth disconnected by remote device
- add code to notify about remote disconnets
- configuration: /etc/btstack
- single Bluetooth module supported
- transport type: H4, H5, USB
- h4/h5: UART path
- usb: product/vendor ID
- logging mode: text, bluez, packetlogger
- add configure option for uart flowcontrol
- create <btstack/errors.h>
- Bluetooth low-power modes useful
== USB Support ==
- Store array of data sources to be able to remove them on usb_close
- create little "reserve Bluetooth module on Mac OS X" tool
== Objective-C Interface ==
- have a look at External Accessory interface by Apple - it's quite similar
- move connection methods to BTdevice (get more object oriented)
- initWithAddress:(bd_addr_t *)addr
- setters private
- implement l2cap code
- implement rfcomm code
- animate discovery dialog:
* use indexPathsForVisibleRows and cellForRowAtIndexPath: when you want to refresh just the cells that are on the screen
* use insertRowsAtIndexPaths:withRowAnimation: to add rows
* use deleteRowsAtIndexPaths:withRowAnimation: to remove them-
== Refactor/Improve Architecture ==
- add linked_list_iterator that can remove elements (used by l2cap_close_connection and sdp_unregister_services_for_connection
- clean up control flow
- l2cap directly sends data over socket: good/bad?
- split daemon into stack parts
- should there be STACK API/interface?
- unify packet generation
- btstack events
- cmd packets
- l2cap commands
- auto-generate code for sending commands from structured text input file
- devise concept for access to event data
- auto-generate event struct getter? STRUCTURE_get_FIELD
