Error 129 (0x81) means GATT_INTERNAL_ERROR (see https://android.googlesource.com/platform/external/bluetooth/bluedroid/+/android-4.3_r1.1/stack/include/gatt_api.h). That's unfortunately not very precise. Could you tell me on which kind of smartphone that occurs?

StevenMohr commented 7 years ago

When I read the log you attached I can see that discoverServices was started twice. That might be an issue and might result in an error for the search. I would introduce a boolean flag like discoveryIsInProgress in your BluetoothLeService and only a start a new service discovery if another one isn't in progress. The problem might be that a second discovery is started while the first is in progress. The Bluetooth LE stack is really fragile ...

manikavi commented 7 years ago

@StevenMohr

Okay,

manikavi commented 7 years ago

@StevenMohr , did you check that?

StevenMohr commented 7 years ago

@manikavi No, I can't. I don't have a blood pressure meter available. Did the fix change anything?

manikavi commented 7 years ago

No sir,I'm still trying to get readings from BP device

StevenMohr commented 7 years ago

@manikavi Could you push your changes to GitHub?

manikavi commented 7 years ago

@StevenMohr ,

This Log is From Same Phone,now didnt get 129 error,did n't do any modification in code,I think I clicked on Scan menu which appears on top right corner twice ,so discoverServices() function is called twice

@StevenMohr ,

In this link ,there is no description for status 19,What could be the reason for this?

https://developer.android.com/reference/android/bluetooth/BluetoothGatt.html#GATT_SUCCESS

StevenMohr commented 7 years ago

@manikavi Yes, the error codes are mostly not included in the official docs. You have to search for them in the Android source code. Error code 19 (0x13) is supposed to be GATT_CONN_TERMINATE_PEER_USER. This means that the device you're connected to terminated the connection. So we have to look into the read measurements part.

manikavi commented 7 years ago

@StevenMohr , According to the status code we have to establish the connection with remote device again?

StevenMohr commented 7 years ago

When the peer device resets the connection, it usually means that there was some kind of timeout or the device couldn't process one of our request. Looking at the code it might be the case that the device is waiting for requests and then terminates the connection. You should get rid of the part of DeviceControlActivity where it shows the available services. After you discovered the services, choose the blood pressure service and asks for the measurements without waiting for some UI input.
