can LAMW work with BLE devices?

I haven't been able to implement it yet ... BLE is a difficult task for me .... (I don't really understand the subject ...)

Edited:  Can you do some test? (I dont have a BLE device...)

the result of GetCharacteristicProperties is cpUnknown,  but I think it should be READ, WRITE and NOTIFY, just like the second picture

Hi

Thanks for your reply. I've spent most of the last week trying to get it to work and tonight I came to the conclusion there is a bug.
It finds "myserviceUUID" OK, and the correct UUIDs for the characteristics, but it will not get the properties of them. Strangely it will get the properties of the of the genetic characteristics.

Do you have any idea on a time scale, or should I look into another option? 

Thanks

Brian

Sorry.... No.

The "jBluetoothLowEnergy.java"   from  "androidmodulewizard\android_wizard\smartdesigner\java"

Need some fix....

I think I need some help... I have little specific BLE knowledge...
I don't work with BLE devices.... I don't have one to test...
