Pairing a Microsoft Windows App

[EdHa_4455331]

I am trying to get a Microsoft Windows App to pair with a CYBLE-416045-02 module using pin confirmation. I can successfully pair with the module using CySmart, so I am pretty sure that I have the basics correct on the module side. But my windows app goes off the rails. Of course, one of the big differences is that CySmart goes through its custom BLE dongle, while the Windows app tries to use the PCs bluethooth system.

In the Windows app, I followed the guidance at Pair devices - UWP applications | Microsoft Docs and did the following:

DevicePairingKinds pk = DevicePairingKinds.ConfirmPinMatch;

  DeviceInformation deviceInfo = btdev.DeviceInformation;
  DeviceInformationPairing devicePairing = deviceInfo.Pairing;
  DeviceInformationCustomPairing custom = devicePairing.Custom;

  custom.PairingRequested += pairhandle;

  DevicePairingResult result = await custom.PairAsync(pk);

  custom.PairingRequested -= pairhandle;

But on the module side I get:

CY_BLE_EVT_GAP_AUTH_REQ: bdHandle=1, security=3, bonding=1, ekeySize=10, pairing=1, err=0

CY_BLE_EVT_GAP_SMP_NEGOTIATED_AUTH_INFO: bdHandle =1, security=3, bonding=1, ekeySize=10, pairing= 1, err=0

CY_BLE_EVT_GAP_AUTH_FAILED: bdHandle=1, securitye0, bonding=50, ekeySize=2, pairing= a, err=a

If I change the security levels in the module to not require pairing, all the rest of the system works as expected. I can connect, get the characteristics and read and write to them.

So, has anybody out there managed to pair with a Psoc 6 module from a windows app using ANY level of pairing? And if so, how did you do it?

Thanks,

Hello EdHa_4455331 ,

Please let me know the windows version which you are using. Are you using the custom app in your windows ? Please provide some information on the Microsoft Windows APP.
Could you please check with the "CE212742_BLE_4.2_DataLength_Security_Privacy" code example project from the PSoC Creator and let me know the observations ?

Thanks,
P Yugandhar.

Thank you for your previous prompt response. I was called away for a few days with a crisis on another project.

Yes, I am using a custom Windows app. I am running Windows 10 Enterprise version 10.0.17134 with Visual Studio 2017 with all the options listed below.

I will also check out the code example that you have suggested. It may give me a clue. OTOH, I can successfully pair with CySmart complete with the 6-digit number popping up on both sides for confirmation. So if it works with CySmart, what is Microsoft doing that is making it go crazy? We will have to keep on digging...
