Android: enable DLE

[CheMax]

Hello,

At the moment, there is a need to develop an application for Android to communicate with our device. And we encountered the following difficulties: using the standard android library from android studio for working with BLUs, we were not able to enable extended packet lengths (DLE). The increase in MTU in this case occurs correctly to a value of 247.

On the device, the use of DLE is allowed, since the PC application correctly increases it (tracked by the log and using the sniffer).Testing the bandwidth of the channel  (PHY 1M) showed an average speed of 24 kB/s, which in principle is not bad, but I would like to reach the maximum.

In addition, in your video (High throughput camera demo) on working with the camera, you obviously got to work in large packages, judging by the speed.

Could you share a way to achieve such speed in this example, or perhaps the code of this application for study?

Hi,

You can find the code for the application used in the demo video here.

The application might not work with your device "out-of-the-box", since it is made for a demo application. But you can use the code to get a better understanding of how things have been done.
