The db.h file generated from db.gatt needs to be re-created. 24- TLV: global TLV instance available via btstack_tlv_get_instance() (src/btstack_tlv.h) 25- TLV: POSIX implementation that appends to a file on disk (platform/posix/btstack_tlv_posix.c 26- LE Device DB TLV: overwrite oldest entry if no free entries available 27- SM: allow to set fixed passkey in display role using sm_use_fixed_passkey_in_display_role 28- Example/hid_host_demo with HID parser and support for basic US keyboard layout 29- EM9304: custom HCI Transport implementation for EM9304 on top of btstack_em9304_spi.h platform abstraction only requires hal_em9304_spi.h to be implemented for new ports 30- Port for Apollo2 MCU with EM9304 (ports/apollo2-em9304) 31 32### Changed 33- panu_demo: uses btstack_network.h now 34- WICED: configure printf to replace Linefeed with CRLF 35- SBC: split btstack_sbc_bludroid.c into seperate encoder and decoder implementations 36 37### Fixed 38- RFCOMM: support connection requests during connection failure 39- L2CAP: support connection requests during connection failure 40- L2CAP: fix default remote MTU as 672 instead of 48 (Minimal MTU) 41- HCI: avoid double free during halting 42- SM: fixed reconnect using legacy pairing in slave role 43 44 45
