BLE android多个传感器

Question

I actually have the project to develop an android application BLE which can connect and read multiple sensor (My version should be able to connect up to 7 devices, but I want to connect only 2 in the first time).

I read a lot of informations about that and have a knowledges of the global working-way (one thread by connection, queue of requests, etc) but I'm really not familiar with the JAVA language. I found arround a billion of topics with this subject but all of them are a bit old, so here is my questions :

• Does exists a working example which demontrate the implementation of this implementation's kind (One android with few exotics sensors like CC2650 Sensortag) ?
• To implement that application, should we create a library like Rami Martin did on his example : http://arissa34.github.io/Android-Multi-Bluetooth-Library/ or is it possible to create it without change the android library ?

Answer 1

There is no easy-to-use open sources libraries for BLE Android at the moment, almost of them are also not updated.
I also spent a long time to look for a good example and library, but all of them are one-device connection only. Finally, I went with this library.

You can use this to connect with multiple devices easily. However, to get data from all of them, it is a little bit harder.

This is also not maintained currently but it is the best one for me. You can take a look at sample-app for more details.

I do connect to several sensors but I just do it by connecting one after one, collect the data and disconnect then connect the next on etc... This is just working well. Isn't this OK for you?
