This is linked to this previous question: Set Nest target humidity via API
The field reflects the value from the thermostat's built-in humidity sensor, the thermostat doesn't have any capability of controlling a humidifer.
My question is based on this topic and it seems to doesn't work.
I'm looking for any information on how I can change the address format from ss58 to bech32?
Do I need to implement?
impl AddressMapping
I'd have a look at https://github.com/interlay/interbtc as they are a btc polkadot bridge, so might have covered this ground.
I'm making a hide-and-seek game app with Android studio. So my application needs to know the location information of each player's device (no coordinates are required, like GPS).
At first, this video (https://www.youtube.com/watch?We tried to create IMUs using acceleration sensors, gyroscopes and geomagnetic sensors like v=6ijArKE8vKU), but after searching and finding out in many ways, we decided to do it in a different way.
So the way I'm thinking now is to collect the current location of each player with the information from ARCore's Concurrent Odometry and Mapping Process.
However, most documents and tutorials seem to start with the object placement, anchor part.
How can I get the current player's location in ARCore or the motion tracking information on my device?
you can use FirstPersonCamera.transform.position to get the current x y z position of your device in current scene
I have developed an app where the executing device acts as a beacon. As a scan result, different BLE devices appear with their respective RSSI value.
Is it possible to use these RSSI values to determine the own current position with AoA? I have already read some documentation on this, but I have not found anything like an algorithm.
How can AoA be implemented?
Can someone tell me the necessary steps to do this?
Is triangulation also possible if the referenced 3 points are moving or do you only search for the 3 nearest points??
Is it possible to search for all iBeacons which are nearby? I know it's possible to search iBeacons by UUID. But i want to find all iBeacons nearby.
An iBeacon is a region, and has as defining property the UUID. Therefore, you can only search for the ones matching a UUID.
After you find one or more with a specific UUID, you can figure out which is closest using the delegate callbacks, where the beacons are stored in an array ordered by distance.
There is great sample code on this and also a pretty detailed WWDC video session: "What's new in Core Location"
iBeacons are higher-level constructs than regular BLE peripherals. From what can be determined from the Apple docs, beacons are tied to their service UUID. i.e., a family of beacons is a "region" and a you go into and out of a region based on the range and visibility of a beacon to YOU, not the other way around. Unfortunately Apple has used the term region, which most of us probably associate with MapKit, so this is adding to the general confusion
Here's the bad news: You can only scan for ProximityUUIDs that you know, there is no "wildcard" proximityUUID. Additionally, CLBeacons don't expose the much in the way of lower level CoreBluetooth guts so if you want to find all beacons that happen to be near you, you'll have to use CoreBluetooth, scan for peripherals, then look though the returned peripheries and query each one them to find beacons. Of course Apple has neither registered (with the Bluetooth SIG) or (yet) published the iBeacon characteristics so, you'll need a BT sniffer to reverse engineer what constitutes an iBeacon from any other BLE device.
each APP would use it's own specific UUID, using the "major" and "minor" integer values to differentiate between beacons.
for example, the UUID would be associated with a chain of shops, major would identify the shop, and minor the aisle, or even a group of products.
scanning for unknown UUID's would not be very useful, as your app would not know what to do with the information.
the UUID is generated once and for all, using the "uuidgen" command in the terminal.
sadly there is no protocol to actually communicate with beacons, hence there is no standard to get the location of a beacon, or any other useful info.
it would have been so much better if we could open a connection to a beacon, usually the closest one, and obtain additional data from it, without having to be on the same WIFI network.
you either have to use bonjour to communicate with the device over WIFI, or use the major and minor id to obtain data from a webservice of some kind.
Unfortunately you cannot at this time search for an arbitrary iBeacon without first knowing the proximityUUID value. I've tried writing directly to COREBluetooth and, although you can discover and connect to transmitting beacons in your area, what you get back is jibberish with no relation to the BLE UUID. So you can't even confirm that the peripheral you have connected to is in fact an iBeacon.
This does not appear to be a limitation of the BLE spec, rather it is a limitation that has been imposed by Apple. It also appears that this limitation does not exist for the Android platform.
Until this gap is closed, Android will have a significant advantage over iOS in this area.
I disagree with previous comments that scanning for UUIDs would be useless. On the contrary, if you knew the beacon UUID, you could create a map of beacon/location/subject in the cloud and use it to navigate (assuming the beacon was fixed) using a web service. You could crowd-source the data so that eventually a very rich database of beacon UUID/location pairs would be available to all who wanted to write location apps. Perhaps this is why Apple is hiding the info; they may be holding this back for their own purposes.
According to Radius Networks (authors of the AltBeacon spec and the android-beacon-library it's not possible to identify a beacon using CoreBluetooth
