We'll prefer to pair and discover services on connected bearer first. There was a problem with pairing, that select_conn_bearer returned BR/EDR even when we have connection to LE bearer only. In these situation we should pair over connected bearer, since connection to another bearer can fail. Similar problem with discovery that after connection on LE bearer discovery was requested on BR/EDR bearer which can cause connection error (e.g. Page Timeout). --- src/device.c | 21 ++++++++++++++------- 1 file changed, 14 insertions(+), 7 deletions(-) diff --git a/src/device.c b/src/device.c index 6f28e261e..446e978ee 100644 --- a/src/device.c +++ b/src/device.c @@ -2504,6 +2504,16 @@ static uint8_t select_conn_bearer(struct btd_device *dev) return dev->bdaddr_type; } +static uint8_t select_active_bearer(struct btd_device *dev) +{ + if (dev->bredr_state.connected) + return BDADDR_BREDR; + else if (dev->le_state.connected) + return dev->bdaddr_type == BDADDR_BREDR + ?
