In my office we have 11 different mobile devices that we use for testing our apps. We have Android Tablets, iPhone, iPads and some android phones.
Lately I can't seem to find an efficient charging procedure.
Some cables only charge (the devices) when plugged into USB (mac mostly), some cables only charge certain devices and some cables only connect with the computer but not charge.
We tried to buy new cables but it didn't work.
What would be a good strategy and setup for this kind of thing?

Is it possible to communicate with a mobile device supporting Bluetooth LE from UEFI of a system? UEFI specification 2.6 adds support for Bluetooth but I dont see any new laptops supporting it and also the specification doesnt say anything about Bluetooth LE.
This feature is possible. However, its not related to UEFI Mode but this feature has to be embedded into the bluetooth chip itself. This feature is generally known as Headless mode of Bluetooth Chip.
The Bluetooth chips contain two firmwares. One firmware for general BT functionality and the other firmware contain a lite Bluetooth stack which contain a very cut down version of Bluetooth stack which can support BLE feature. So, when your laptop either gets shutdown or goes to sleep, your BT chip goes into headless mode and start advertising itself to other BLE device. Other ble device like mobile can see this and can connect to it and start your laptop.
This feature is however, not present in any laptop known to me. But you find a good example of this in Samsung's smart TV. You can switch on your TV from samsung mobile using ble.
I'm writing a mobile application on Marmalade SDK. How can I connect to other device via bluetooth?
https://answers.madewithmarmalade.com/questions/7285/bluetooth-support.html
No, Marmalade doesn't have a Bluetooth API. However, you could write
an extension to do it.
iOS has a CoreBluetooth API that allows you to interact with devices
supporting the Bluetooth 4 Low Energy GATT profile - this is only
supported from iOS 5/iPhone 4S/iPad3 and up, and will only
interoperate with Bluetooth 4 LE capable peripherals exposing a GATT
service. For earlier iOS devices, the only option is to use Apple's
proprietary iAP protocol, which means you can't "talk" to generic
Bluetooth devices - only those that implement iAP.
Android on the other hand offers Bluetooth 2.x + EDR connectivity. A
number of profiles (e.g. RFCOMM, A2DP) are supported. However, Android
doesn't have an API for Bluetooth 4 LE yet.
So, currently, the situation, from a cross-platform point of view, is
quite fragmented and it isn't straightforward to implement a
one-size-fits all Bluetooth connectivity solution.
I'm trying to profile energy consumption in a real Windows 10 mobile device with ARM-class processor. However, to do so, we need to disconnect from USB cable, because a direct feeding by means of USB seems to distort measurements, in addition energy-aware objects (like AggregateBattery) defaults to null. But when device is disconnected from the computer, and connected via WiFi, seems that Visual Studio does not support such remote debugging. VS2015 remote tools are not available for Windows 10 mobile phones with ARM processors, at least, we couldn't find a suitable installer for the platform. Is there a way to profile energy consumption for a UWP application, running in a real Win10 mobile device, using VS2015?
Very strange issue, no results that I could find from google searches.
I am running Windows 7 64 bit. Everything Windows related is up to date, and so are all USB drivers. My computer is a laptop from Puget Systems.
My computer has three USB inputs; one USB 2.0, and two USB 3.0s. 2.0 versus 3.0 doesn't really matter though, because this issue happens with all three drives.
Heres the issue: When connected, USB devices are found, and recognized. 5-30 sec later, they disconnect, only to reconnect in a couple seconds. The cycle of disconnecting/reconnecting continues indefinitely. I have not been successful with keeping USB devices connected for more than ~30 seconds.
At this point, it could be any number of things causing this issue. But this is where it gets weird. This issue ONLY happens with mobile devices, and it happens with ALL mobile devices. By mobile devices I mean phones and iPods. I have tested my Samsung Galaxy S4, an iPod Classic, an iPod touch, an iPod nano, a Droid Turbo, and an iPhone 5. This issue occurred with all of these devices. The issue did NOT occur at all with my 2TB Seagate backup harddrive, my 1TB WD harddrive, several USB pen drives, my external keyboard, or my wireless mouse USB receiver that is plugged in nearly 24/7 in my USB 2.0 drive. My Xbox One controller disconnected 3 times in a row once, but that only happened once so it might have been a fluke...?
Anyways, what could be the reason for this strangely specific issue? Does anyone have any answers or has anyone experienced something similar?
Improper drive installation? Make sure your drivers are installed correctly. Try uninstalling and reinstalling them. If this does not work try to see if it is your USB cable or mobile device's port. (Test by altering to charge the device from a wall adapter) It could also be your computers port but you said in the title that it is only happening for mobile devices.
Reinstall the drivers to the devices you are having problems with. (Oh someone beat me too it.)
Am using Nokia 5228 phone. I want to install the other Phone OS like Nokia 5230. Is this possible or Not?
As far as I know this is impossible to achieve. Since the Sw is different for different phones.
Even though two phones appears to look same in functionality, obviously they will have some different functionality some where.. [Either in GUI or in the back end].
As well as, the device S/w are designed as to recognize the particular mobile phones for which they are made for [by serial number/ model number or may be anything else only.]
Also you'll have to get the S/w first which is very difficult to get.
You ca not change anything in the device so that the device gets other phone's S/w.
So conclusion is:
You CAN NOT install the Nokia 5230 OS for Nokia 5228 Phone.
