CC2640: Stack does not send pairing state callback to application

Choongbeom You

Part Number: CC2640

Hello,

The problem with the previous question has not been resolved, so reopen it.

As the previous thread, stack does not send pairing state callback to application when connect to iPhone with DLE enabled.

// GAP Bond Manager Callbacks
static gapBondCBs_t Pairing_BondMgrCBs =
{
(pfnPasscodeCB_t)Pairing_passcodeCB, // Passcode callback (not used by application)
Pairing_pairStateCB // Pairing / Bonding state Callback (not used by application)
};

The "Pairing_pairStateCB" function must be called every connection.

But if the DLE is enabled, sometimes it's not called.

I guess it's about stack's heap overflow or something like that by enabling DLE.

It seems that there is a problem with the stack that the callback function is not called no matter what problem occurs.

Thanks,

Calvin

Hi Calvin,

Could you please provide the following information:

the SDK / BLE stack version you are using
the example you are using and the modification you have made
the model / version of the iPone you are using
some BLE sniffer logs showing the problem

Thanks and regards,

Hi,

ble_sdk_2_02_05_02
It's from glucose_sensor and peripheral example originally but it's modified a lot except the basic operation of stackmsg, gattmsg, appmsg and etc. I cannot share the file. If you let me know the points that you want to check, I can explain.
iPhone 12 Pro / iOS 14.1
It's uploaded on the previous thread.

Thanks,

Calvin

Hi Calvin,

Do you manage to reproduce the issue in a unmodified example? For example the out-of-the-box simple_peripheral example?

Best regards,

Hi Clément,

I cannot mange to reproduce the issue in a unmodified example in my environment.

I think TI need code analysis and test with iPhone for this issue.

Also this issue not relevant with GATT_RegisterForMsgs thing of the new thread.

It's reproduced after adding it still.

I close this thread because I'll not use the DLE.

But, I'll reopen this issue if the situation comes when I must use it.

Thanks,

Calvin
