Ensure TimeChangeReceiver alarm is scheduled when enabling
datetime_synconconnect and registering TimeChangeReceiver broadcast
receiver.
It is important to re-schedule the alarm after registering broadcast
receiver, because:
1. if broadcast receiver was unregistered while previous alarm arrived,
there is no alarm scheduled;
2. re-scheduling the alarm resets the periodic time sync timer when
first device is connected (which is desired).
It is important to re-schedule the alarm when datetime_synconconnect
gets enabled, because there might be no alarm scheduled.
Call onSetTime() when enabling datetime_synconconnect.
Sync time every 43 hours, 53 minutes and 23 seconds.
Interval is a bit smaller than 2 days.
Interval is a prime (in seconds) so time of sync will slide over time.
If next DST change is less than 48 hours in future, wait for it.
The refactored DiscoveryActivityV2 does not freeze anymore, even under
maximum scanning intensity on older phones, and seems to not have
introduced any regressions.
Mi Band HRX: changed DeviceType key for MIBAND_HRX
Mi Band HRX: added migration to MIBAND_HRX
Mi Band HRX: added devicetype string for MIBAND_HRX
Huami HRX: removed redundant null check
Huami HRX: removed redundant supports callback
- get rid of pre-lollipop BLE discovery (nowadays we support only lollipop and above) and related preference
- get rid of the sequenced BT-then-BLE-scan that wasn't working reliably anyway and was causing a recursion
- add a caching layer for already processed devices (the same device is found multiple times during discovery)
- add a caching layer for device name in GBDeviceCandidate (many coordinators will ask for it, and it's a very expensive operation)
The previous one was too long, now that we loop it.
This one should be a sane default, even for devices that do not support
it (eg. Bip), as the total time is 1.5s.
