How can we work around to speed up the Android BLE Transfer progress?

each device acts as a server so that it can have a server socket to listen for connections. When the other device initializes the connection, it becomes the client. In addition, when the device becomes "host", it will open a server socket and the other devices will simply connect.Note:if the devices has not been previously paired and then the

This error translation means: You cannot create handler in a thread that does not have looper.prepare.At first I was puzzled that I did not use the worker thread at all, nor did I create a handler. The code for the error is as follows: //Device scan callback.

The last time I explained the basic usage of Android Bluetooth, I went into depth and discussed the hidden APIs of Bluetooth. Anyone who has used Android settings (Setting) knows that pairing and unpairing can be established after Bluetooth search, but these two functions ar

First, because there is no Bluetooth device on the simulator, we need an Android system containing a bluetooth device. Second, to operate the bluetooth device on the

Android Wear was released on March 19, 2014 and has Moto 360 and LG Watch two products. The source is not yet open, but the developer can download its image and the corresponding SDK, so that developers can do the pre-development through the simulator. In fact, Android wear consists of two parts, part of the operating system running on wearable devices, part of the SDK for handheld devices (mobile, tablet)

Develop Android applicationsProgramYou may need to test between multiple devices, including emulator and handheld devices. When you need to delete an app in development, you need to use the ADB uninstall command. Its explanation is as follows: ADB uninstall [-K] ('-K' means keep the data and cache Directories) By default, this command can run normally when one devi
