How can I set up a GoPro camera to stream to the web over Wi-Fi? My plan is to purchase a waterproof solar generator,connect the GoPro for a continual power source, stream video to a website and not have to touch the actual GoPro camera.
My first reaction is to ask you a question. Is there a particular reason you want to use a GoPro?I love my GoPro Heros. I own a 1 and a 2. I’m sure I’ll soon own a 3. They’re great for a lot of things, but this may not be the best camera for this job.Generally, to live stream to a website you need a camera to capture the image, a computer to encode the image and a server to stream the video on your website. GoPro doesn’t officially support any software that’s capable of capturing the WiFi video stream to a computer. Their apps are phone/tablet –based. There are ways to hack into the GoPro’s WiFi network and use VLC to view the video stream, but it’s not a perfect solution.There are also some third parties like WiGo that are developing computer-based applications, but nothing officially connected to the company.Then consider that the GoPro’s WiFi stream is a low-res preview, not full resolution video. I haven’t found official specs on what we’re actually getting via preview, so I’m not even sure we’re getting full frame rate. For your needs this might be just fine, but there are other solutions out there that can stream HD.Then there’s the WiFi signal itself. It’s low power meaning short range, up to 600ft line of site. Realistically I’d call that 250ft. Combine the short range with the ad-hoc style of networking that GoPro used to communicate and you have a distance issue that will be difficult to solve without a bunch of repeaters and extra power requirements.I think you’d be better off looking into WiFi security systems. These systems are designed to more closely do what you’re asking. Open network configuration utilities that support different protocols, longer range signals, client software, IR for night viewing… But you’ll still have to come up with a wireless network solution if the area you’re viewing is remote. WiFi may not be the answer. You might look into 4G services.GoPro makes a cool and capable little tool for the video guy’s toolbox. In this case however, I don’t think it’s the right tool for the job.
How do I transfer live videos from underwater using Raspberry Pi?
Here is my primary reference for this answer: How deep underwater can Bluetooth reliably transmit?Water absorbs high frequencies like 2.4GHz very well… That is also why submarines use sonar and not radar underwater. Extremely low frequencies (10KHz and lower) are used to communicate to submarines when submerged.By the looks of it, it will be very difficult to get a reliable wireless connection to the surface with any radio technology that transmits fast enough to do live video.If the video stream is very very small (think QVGA at 320x240, or maybe VGA at 640x480) you could look into attaching some sort of XBee transceiver on both devices and broadcasting at a low enough baudrate to transmit through water. (e.g.: SparkFun Electronics)There are countless tutorials online explaining how to marry a XBee to a Raspberry Pi.Another option would be to have a floating umbilical tether to a radio module above the surface. This is the method that ROV’s use, where the need for fast and reliable communication with the surface is critical.If you have any more details about your project, I’m sure that us Quorans can come up with some more specific ideas. Specifically, what depth do you plan to be capturing video at, and how much bandwidth do you want to handle?
Can a Mevo camera stream video using only the iPhone Bluetooth connection and a 4G connection with no Wifi?
Gary is correct. But if you have unlimited 4G data with your carrier or you need this connection only on occasion and only for short bursts, then you can turn on Personal Hotspot (in Settings) in your iPhone and connect your camera to it.
Is there a device that allows you to sync photos from a digital camera to an iOS device via Bluetooth or wifi?
It turns out that Eye-Fi's SD card and companion (universal) iOS app [1] are designed precisely for this use case. The app's description states the following:With an Eye-Fi X2 card, you can instantly upload full resolution photos & videos directly from your digital camera to your iPhone or iPad, wherever you are. Connect your Eye-Fi X2 card directly to your iPhone or iPad anywhere using Direct Mode - no tethering, Wi-Fi router or Wi-Fi hotspot required. Just turn your camera on, and let Eye-Fi do the work for you.Thanks to the Eye-Fi app, you can automatically back up and organize photos and videos by date on your home computer, or share them on your favorite online site. Now you can get all your photos backed up and organized, whether you took them with your digital camera or iPhone/iPad. No cables. No hassles.[1] itunes.apple.com/app/eye-fi/id306011124?mt=8This answer was cross-posted from my answer to Digital Cameras: Is there a digital camera that syncs photos to your phone, tablet and/or computer via Bluetooth or wifi?
How do I acquire sensor data from a smart phone to a PC? How do you use smart phone sensors for robotic applications?
A modern smart phone has an array of sensors which work together efficiently to provide extra-ordinary features to the end user.After extensive searching of methods to use the sensors of the mobile phones for embedded projects, I found an app by name Sensoduino.Link to the complete description:SensoDuinoMy team has successfully used this app (in Redmi Prime 2) to stream data to a micro controller interfaced with a HC 05 ( bluetooth module).It can be even transferred to PC ( see the link )Following are the things we observed during our usage:1) GPS fix is not so reliable indoors.2) Configure the “recent button” (bottom left ) in your smart phone to options mode in case if you don’t have any menu popping up in the app.3) Google Play Store may state that your phone is incompatible for the app. We downloaded from the link provided and everything worked just fine.4) I could not successfully communicate with the inbuilt blue tooth module of Intel Edison. HC-05 module is the most reliable module for this app.5) Turn on your Bluetooth and GPS before opening the app6) It worked for us in the 9600 Baud Rate.7) Tweak the code provided in the page for hassle free testing.8) You can log the sensor data in your mobile phone using the log icon near the sensors.Note: This app might drain your phone’s battery
How do I scan for wifi and cellular (2g, 3g, 4g) access points and network using linux?
The question quite not clear what you want to achieve, but I will try to provide the information based on what you have given. What you are trying to do is basically similar to project fi from google. Project Fi . To do equivalent stuff you need to make an intelligent decision in choosing the network with 1.Good signal strength (you can set hard thresholds). There are several wifi scanning programs available which can work for your cause. You can feed that information in your script which can yield the best output.2.send small packets on each network and see which one has less round trip time and choose that as your best network. You might need multiple interfaces on your linux to achieve this.3. If you are going to use of the dongles for 4g such as aircard 340U, it comes with AT&T software which can select 4g when there is no wifi etc. but its not intelligentAll the above solutions are complicated and require time and effort to do it. Easiest option out of this would be to connect the raspberry pi with an ethernet cable to your router.

How many Bluetooth devices can be paired at the same time on iPhone 6s plus?
Phones running less than bluetooth V4.2 would need to use the services of a bluetooth splitter which would probably set you back $50 or so.Devices running 4.2 can apparently feed data to 2 bluetooth units which is brought about by pairing the two units in sequence, shutting them down and then reconnecting in the same sequence. Not tried it so this is hearsay.Some manufacturers are bringing out speakers and headphones with bluetooth V5 which will do wonderful things but at this stage there are no phones running V5 so its a bit of a moot point.Here is how my mickey mouse setup works, if me and the Missus want to listen at the same time without waking the kids. I have 2 Bluedio Bluetooth headsets, I pair and connect unit 1 and then run a 3.5 mm cable (supplied) to the other headset. Limiting factor is the cable but we usually use this setup when relaxing after dinner.From what I gather there is not a vast amount of money being poured into bluetooth, its old technology with a narrow bandwidth and limited range. Wifi seems to be where the dollars are going. Imagine a player that can handle CDs DVDS SD cards as well as USB drives and send a very high quality signal to anywhere in your home or yard.Wont be long.
