Is there a way to take data from Matlab Mobile without an internet connection? I have my computer and phone linked through USB and would like to use the GPS in my phone to keep track of the position of my car. Ideally the data would just flow from my GPS sensors to the Matlab App and then through the USB connection and into Matlab. I guess what I'm asking is is there a way to connect my phone and computer without using internet?
They just have to be in the same network. If you are on the go just use your phone as a wifi hotspot and connect to your computer. No internet required.

I am working with android device for POS system. I need to do data backup by uploading data to portable 4G router with tf card. In my device, I am getting internet from mobile data. There is no internet in my portable 4G router. I am only using it for backup purpose since my device doesn't have sd card slot.
Ok please don't suggest anything other than my question. This is the proof of concept i need to prepared. Other alternative, my colleague and I are already brainstorming.
DEVICE INFO
connected with mobile data (have internet)
connected with wifi (no internet)
GOAL
to use wifi interface to upload data from device.
PROBLEM
network call only using network interface with internet. In my case mobile data. I have no idea how to use wifi interface to make network call instead of using mobile data interface.
IMPORTANT
device must always connected with mobile data and wifi
cannot put sim card to wifi router. This is to prevent portable 4G router from being used as hotspot after working hours.
I have an Android device that has wifi and Bluetooth modules. I want to build applications to connect the device to the internet using a smartphone's data connection. Is this possible?
The smartphone will have wifi as well as data connection. Can the smartphone's data connection be shared through Bluetooth? Or is there better alternatives like wifi-direct or NFC? I am aware that enabling Hotspot on the smartphone is an option. But with hotspot, the issue of wifi being turned off makes it not usable for my use case. Is there any alternative to wifi-hotspot?
What will be the best option for this and what things should I consider when building my applications and services?
NFC is definitely not the answer, the data rate is far too slow and the connection unreliable and the OS does not allow it.
You might be better with a USB ethernet adapter if your phone support USB On The Go (OTG)
Your phone should already support sharing a data connection using Bluetooth. This is called Bluetooth tethering. But you also have wifi, so wifi tethering is also an option to share your data connection. No additional app is required.
I have an Android watch that can be in one of the following:
1a. standalone - connected to a WiFi network directly;
1b. standalone - connected via a cellular link (if SIM present, unlocked, etc.);
2. bluetooth connected to a phone and using the phone's connection (WiFi/cellular);
It can also be that both the watch and the phone have a SIM (though this is less important).
On the watch I run a standalone app (no counterpart app/service on the phone) and I need to find the 'end' connection type I have when tethering. Namely, using the watch only, I need to know if I am tethering via a WiFi or via a cellular connection.
Or, in other words, when tethering, I need to know if the phone (to which the watch is connected via bluetooth) sends my data further using WiFi or a cellular connection.
I did look around for a solution but what I found only allows identifying the type of connection the watch has, e.g. WiFi, cellular or bluetooth.
Is this even possible? Thanks in advance for your help!
Can someone tell me is there a way to connect to a device with Wifi, yet continue to the cellular connection for internet data? Basically, I need to connect my phone to drone Wifi but I want to be able to use the cellular connection for internet access, for example, to share photos I have taken from the drone.
I see it says Android but what version of Android and what model is the phone (Samsung, LG, etc) you are trying to connect with? Also, what drone model is it that you are flying?
If you are using Samsung I would suggest trying the data boost option that allows you to use both wifi and mobile data, they advertise it as a faster way to download things but I have a feeling this will help in your case as well, if not I be interested in your results.
I have a device that creates a WiFi network that is not connected to the internet. This device hosts a website using IIS. To operate the device, a smartphone connects to the WiFi and browses the site. The smartphone needs to get data from an api (internet) and pass it to the website on the device.
I have tried to remove the default gateway setting from the DHCP server on the local WiFi, but this is not permitted on the device.
I have not been able to find an app that will allow both WiFi and Cellular data to be used simultaneously.
If I were to allow the device to connect to a hot spot that the smartphone creates, the smart phone cannot access the device's WAP.
The next option I'm considering is to toggle the WiFi Off and On during the process.
I'm wondering if anyone has another solution to this issue?
