From 3d4d9147a8cd086908e658f513a4c4c4cdecaea5 Mon Sep 17 00:00:00 2001 From: Claudio Takahasi Date: Mon, 24 Mar 2014 16:25:42 -0300 Subject: [PATCH] core: Fix creating 128-bit uuid_t based on GATT service sdp_uuid128_create() gets the 128-bit UUID on big-endian (human-readable format) byte order. Service declaration attributes puts the UUIDs in the attribute value field using little endian order. This patch converts the 128-bit UUID from little-endian to big-endian before creating uuid_t. --- src/attrib-server.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/src/attrib-server.c b/src/attrib-server.c index 953a3f231..114c8a147 100644 --- a/src/attrib-server.c +++ b/src/attrib-server.c @@ -318,9 +318,13 @@ static uint32_t attrib_create_sdp_new(struct gatt_server *server, if (a->len == 2) sdp_uuid16_create(&svc, get_le16(a->data)); - else if (a->len == 16) - sdp_uuid128_create(&svc, a->data); - else + else if (a->len == 16) { + uint8_t be128[16]; + + /* Converting from LE to BE */ + bswap_128(a->data, be128); + sdp_uuid128_create(&svc, be128); + } else return 0; record = server_record_new(&svc, handle, end); -- 2.47.3
