Hi Chenchen and Ming, Sorry for the delay. I think you are right Chenchen, I obtain the same behaviour, so, I guess the problem is in the Android source code... Well, we will wait for a new Android release solving this issue. Regards. On 9 feb, 15:58, Ming ming030...@gmail.com wrote: Exactly same problem with you.

Hi vijay, I'm seeing that you obtain the following error: onHealthDeviceConnectionResult: D-Bus error: org.bluez.Error.HealthError (No matching MDEP found) I guess your Nonin device is a pulse oximeter.

It conects and disconnects and any data had received in the Android. I'm working with a board which is able to simulate several biomedical devices. On the other hand, I have a real device (blood pressure monitor UA-767PBT-C). In that case, the device opens the HDP channel automatically with the smartphone which acts as sink. But the truth is that I don't see anything in the LogCat related to this channel. However, if I try opening the connection channel from the HDP Demo Application, I obtain the same error. Anyway, I have checked all of this in a Linux laptop using the same BlueZ stack that we have in Android and everything works fine. Do you have any solution? Not yet. I'm expecting some feedback.
