Bluetooth Low Energy (BLE) library

[Antti Mauranen]

Hello bluedude,

I did this using Android Open Source tools, adb, fastboot etc. So I did not use the files in the first link at my previous post. But basicly you have to root your device and copy the files into the paths that you can find in zip file.

There is an application at Google Play help to do this, I think the author is the same as in the second link at my previous post. At Google Play he has instructions what to. The link to the application (it has a price of 7.50 €) below:

Hope it helps you.

I hope I do not offend any forum rules when giving this link, I have nothing to do with that Google Play App.

Have you tried the above code?

I will try this code today, tell me what should be installed on the IDE to use this library? also this code is a serial communication example?

 

[Erel]

You need to add the library from the first post to the libraries folder and then check it in the IDE.

Hello Erel, any news about the timetable of write/notify/indicate functions for Bluetooth Low Energy library?

 

[Erel]

Sorry but I do not know when it will be available.

How do you get the MACAddress?

 

[Erel]

You should call Scan and handle the DeviceFound event.

I am able to find the device but BLE_Connected is never reached. I'm just running the code above with a button added to trigger scanning and msgbox to choose the device. Is it the flaky BLE implementation or am I doing something wrong? I'm testing a Nexus 4 and a Polar H7 heart monitor. I use another app to connect them and it (mostly) works fine.

Also, can someone explain that hard coded GetCharacteristic line?

 

[Erel]

Is DeviceFound event raised?

The 00002a00-0000-1000-8000-00805f9b34fb characteristic is the standard "device name" characteristic.

 

[Bulishor]

Thanks Erel. I was able to finally connect to the device (but I have to reset BT before each connection) and I am getting the characteristic. Is there a command that discovers all the services and characteristics of a device? Is there any sample code other than the OP?

 

[Erel]

You can do something like:

Sub BLE_Connected (Services As Map)
  For Each s As BleService In Services.Values
   For Each key As String In s.GetCharacteristics
     Log(key)
      Dim c As BleCharacteristic = s.GetCharacteristics.Get(key)
   Next
 Next

Dear all,iPhone4s and ipad mini test the ble is successful,but android svn is not update the level 18 sdk,have you download the firmware to test?maybe the sumsung product ?

 

[sixteen]

why didn't download platform level 18 from Android SDK in my development directory?maybe be blocked from the site?had anyone download the latest SDK ?only have the level 17 SDK!!

 

[MaFu]

Did you download with sdk manager?
I downloaded the API 18 weeks ago without problems.

 

[sixteen]

is API 18 or SDK level18?I cann't found the 4.3 sdk,but only 4.2.2 ,sdk level17

 

[Erel]

You should install this SDK:

 

[MaFu]

What du you mean: cann't found

Run the Android SDK Manager and you have all levels showing in a tree ready to install.

Can BLE devices be discovered by an old Android BT device ?
Just discovered (with MAC, Name, RSSI), not connected to.

It's for long-working (low consumpting) sensor to be discovered, without connection to it.

 

[Erel]

No. BLE devices are different than the standard Bluetooth devices.

 

[coodtec]

Testing with Nexus 7 II, the device can be found. But link failed.

Is it possible to get more information such as RSSI value, when the device was found?
