16. Re: CySmart API C# example
userc_40153 Mar 20, 2017 12:00 PM (in response to chfuc_293041)Is there anybody from Cypress team who can advice what the correct way of object release while using CySmart dongle. According to API and examples there is two functions for device connection:
1. Dongle connection: dongleMgr.TryGetCySmartDongleCommunicator(info, out m_communicator);2. External device connection: BleMgr.Connect(new CyConnectInfo(deviceAddr, new CyBleConnectionSettings()));
And two functions for device disconnection:
3. Disconnect from external device first: BleMgr.Disconnect(m_peerDevice);
4. Disconnect dongle instance: CySmartDongleMgr.GetInstance().CloseCommunicator(m_communicator);
I wrote simple application that nothing do besides connect to two different devices following 1-4 process. in a while(true) loop. Unfortunately I have memory leak there, I'm sure dll cannot do that, so probably I'm releasing resources in a wrong way, but I cannot find nothing in API or classes (CySmartDongleMgr, ICyBleMgr) that reminds me the other way (except to CySmartDongleMgr::CloseCommunicator and ICyBleMgr::Disconnect)
Please advice.

Hi Artyom,
This was a bug in the dispose implementation of the API.
This is already fixed in CySmart 1.2 SP1 release. You needs to replace the old DLLs with the new DLLs.
This release should be available on the web in WW14 (in another 2/3 weeks time) .
Thanks & Regards,

userc_38901 Apr 7, 2017 6:52 AM (in response to chfuc_293041)Hello,
I´m using the dongle to access to cypress APIs and develop my GUI. In this respect, I would like have your support in the following questions:
1) Is there an event and/or callback from cypress APIs to detect when the BLE device, to which I was already connected, suddenly no more available is, (for instance due to power supply failure), so that my GUI doesn´t crash or get blocked?
2) Is it possible to access to cypress APIs by using another Bluetooth USB (for instance, ASUS Bluetooth USB Sticks), rather than using the CySmart BLE Dongle?
Very appreciated for your help
Nuno Alves

userc_45235 May 13, 2017 8:13 PM (in response to madhul_36)Hi Madhu,
Can you explain a little bit the meaning for this function in C#
ScanCallBack.ScanStatusChangedHandler = status => { };
and
ScanCallBack.ScanResultHandler = status => { };
I found that after execute those command then the Handlers will be not " NULL"
*I'm not good at C# and now I'm trying to call the Cysmart API y LabVIEW.
Regards,
Uthai T.

epr_1639216 May 15, 2017 8:01 AM (in response to chfuc_293041)Timeouts are your friend in the case of unknown disconnections and preventing blocks/crashes.
I don't know what is available specifically for the cysmart library, but I would suspect that you can check return values and events that refer to connections/timeouts/connected-operation functions to see what is going on.

sakec_2521361 Jun 8, 2017 3:25 AM (in response to GauravS_31)Hello,
I'm trying to reuse notification example. for one of my requirement.
Currently without any modifications introduced, i'm connecting USB dongle with a bluetooth device. and enabling notification on one particular characteristic like temperature mode. but when ever i change temperature mode i don't get the notification.
I have attached the screen capture of the cySmart App for the device. the selected characteristic is for temp mode. 00 - C and 01 is F.
when i change the value in cySmart App it get reflected in the Device. Now when i use the Notification Logger example and set notification for temperature mode characteristic and change the mode in device i don't get any notifications.
Can you help me to resolve this issue.

I am aslo facing same issue as Artyom mentioned "while closing communicator I am getting error says Unhandled Exception: System.ObjectDisposedException: Safe handle has been closed ". I have tried new DLLs from CySmart 1.2 SP1 release as you mentioned that
"This was a bug in the dispose implementation of the API.
This is already fixed in CySmart 1.2 SP1 release."
but still I am getting same error. Please provide any solution if it is possible.

naam_1281831 Sep 13, 2017 5:36 AM (in response to madhul_36)Hello Madhu,
Thanks for providing the example, Could you please tell me which characteristic is targeted for READ and WRITE buttons on the Form?
I thought it requires the Characteristic UUID is required for read/write operation, but your example is using CCCD info, how to get a CCCD info for any characteristic, Please clarify this.
Thanks,
Naga.

28. Re: CySmart API C# example
NiBu_1198441 Jan 23, 2018 7:55 AM (in response to naam_1281831)Has anyone successfully paired with a device that is configured with unauthenticated paring with encryption? I'm using code that was posted earlier in this thread. I try to pair with the following line:
err = m_peerDevice.Pair(new CyPairSettings(CySecurityLevel.UNAUTHENTICATED_PAIRING_WITH_ENCRYPTION, false, 16, CyPairingProperties.USE_MITM));
err indicates successful. I've tried changing bonding to true and CyPairingProperities, but nothing seems to work. The OnPairingComplete event is called with a status of BLE_ERROR_GAP_AUTH_PASSKEY_ENTRY_FAILED.
Any ideas?

bebrc_1981346 Mar 20, 2018 1:29 AM (in response to chfuc_293041)Hi
I am really struggling with the CySmart API. I tried a simple connection to a Device. But all I get is a time-out (BLE_ERROR_TOOL_REQUEST_TIMEDOUT).
This is what I do (I removed the error handling from the code, because this works):
CySmartDongleMgr dongleMgr = CySmartDongleMgr.GetInstance();
CyApiErr err = dongleMgr.TryGetCySmartDongleCommunicator(new CyDongleInfo(COM_PORT_NAME, CyDongleInfo.CySmartDongleType.CY5670), out m_communicator);
m_bleMgrCb = new BleMgrCb();
AutoResetEvent sync = new AutoResetEvent(false);
m_bleMgrCb.ConnectionHandler = (result, status) =>
{
if (status == CyStatus.BLE_STATUS_OK)
{
...
}
else
{
...
}
sync.Set();
};
err = BleMgr.Connect(new CyConnectInfo(deviceAddr, new CyBleConnectionSettings()));
Any idea what I am doing wrong? The connection handler is only called when there is a time out.
Thanks in advance
