I purchased a BLE module HM-10 from eBay. But it is a CC41-A actually. Currently I’m working on an IoT project both for Android and IOS. I actually tried to connect this with the IOS mobile app and it connected successfully. But when I try to connect it to Android (Samsung Note 3 and Nexus 5) it rejects pairing. It simply gives an error message saying “Pairing Rejected By CC41-A”. Snapshot.
Please help me to sort this problem.
Tried to find a lot and finally got to know that BLE modules like HM-10 does not have a pairing mode. They connect directly through the app
Try changing the TYPE parameter to 3
using the AT commands (no need to press any button) it will work just like that
BAUD 9600 by default.
after changing it to TYPE 3 it worked for me, didn't get "pairing rejected"
But I'm still having trouble connecting to it via my APP
(working on that part)

I need to bypass device identification by an app.
I have tried the following method to bypass but did not work:
Using VPN
Clear app data
Reinstall app from playstore
Reinstall from downloaded apk file
Change device id (my device is rooted)
Change google account associated in the device
Insert different SIM Card
What data reference in the device that an app used?
Short answer - only a factory reset will clear those identifiers.
Depends on the android version you are using and considering that everything you mentioned above didn't work, The app is probably using an Android Id or a combination of custom GUID'S.
If it's below android 10, even a factory reset won't necessarily help since it might be using the device IMEI for identification.

What's the best device to use (Chromebit, chromecast , android computer,...) to display a website on a tv-screen?
So that we only need to start-up (every morning) the tv and the tv automatically goes to a certain website.
I wanted to use a chromecast but I'm not sure you can go to a website without your computer or smartphone connected to it.
You can program a Raspberry Pie. That will do the job and a lot more.
And like Ashish said, Chrome cast casts a screen on your TV. You can have the site opened in your phone/laptop and it can be casted to your TV. But you would need to open the site in your phone in the first place. But, if you are comfortable with programming, you can get a Raspberry Pie and program it to do whatever you wanna do.
Check it [here] (https://www.raspberrypi.org/)!
chromecast is a device which just cast your another devices screen so you should go for a andriod lcd,led whatever yoy like

I am developing an application which need to use both networks at the same time - via WiFi the app has connection with some external device, and control it, using of 3G network needs to download a firmware for device. But the problem is when you connect to WiFi the system automatically do the disconnect of 3G network. It seems that WiFi has high priority than 3G network, but I need to use them at the same time, it's wrong behavior of the system for me in this case
I saw a couple similar questions, but they have no solution. Is really android has no way for developers to control both networks even for versions higher than 4.03?
How we can solve the problem?
Do it in a linear fashion. Turn off the wifi and download the firmware. Subsequently re-connect to the device (re-enable the wifi) and transfer the locally stored firmware.

I want to connect an android setup box HDMI out to an android tablet to see the screen of the setup box in the tablet. Here I want to interface an android setup box with the android tablet, so that I can test my android app from setup box to a handy tablet. Is there is any hardware connector or any android app to read the HDMI signal from outside???
You would need a tablet with HDMI IN for that, but I think this feature does not exists.
So you can't.
But you can use remote desktop or screen share applications to see what the box is displaying.

I wonder how Android determines when you connect to an open network whether you need to authenticate in your browser or not for the internet connection to be established.
Does it just check if it can reach the WAN by pinging some server or does it query the default gateway address and checks the reply for some kind of information that hints authentication?
I'm curious how this works but I haven't been able to find an answer. Your thoughts?
Android OS is just another Linux distro, hence it works like in any Linux. The rules for connecting to a wireless are independent from the OS, and regulated by the international standard IEEE_802.11. You will find tons of info, just Google it. The connection to a wireless network is done by a special deamon in Linux, called of course usually "network manager". The connection process is too complex to explain here, but you can find everywhere on Google or Wikipedia.
