BWC by storing its connection info into EEPROM and automatically try to
resume the connection at connection lost or power reset until it is paired to
another BWC.
8.2.2 Bluetooth transmission distance
Transmission distance between BWC V4 Hardware….(TBD)
8.2.3 Bluetooth link disconnecting
The Bluetooth link between In-Car Trigger and BWCs would be disconnected
due to the following reason:
1. Low signal or signal blocking
Pull the BWC faraway than defined transmission distance or block the
radiation signal with metal case would decay the Receive Signal Strength
Indicator (RSSI), which will make the Bluetooth link un-stable or even
disconnected.
The link would be re-established when the RSSI raise again due to the
distance between In-Car Trigger and BWC getting closer (within
TBD m)
or signal is un-blocked.
2. New pairing
Perform Bluetooth pairing on the target BWC with other In-Car Trigger or
pairing other BWC to the In-Car Trigger which the target BWC currently
paired with would make the original Bluetooth link between target BWC
and In-Car Trigger be replaced and destroyed.
Refer to pairing decision descript in section 8.1 for all possible condition
which the link would be replaced by a new pairing. Once the link is
replaced, it won’t recover itself unless perform Bluetooth pairing on the
BWC and In-Car Trigger again.
Depend on it is BWC1 or BWC2 disconnected from In-Car Trigger, BWC1 or
BWC2 LED would turn off.
Value of
GAP Status would switch from “ CONNECTED ” to between
“ STARTED ” and “ SCANNING ” periodically. And Value of Disc. Code would be
updated with the code of reason of the last disconnecting.
