CC2642R: GATT_Notification always returns 0x16.

Part Number: CC2642R
Other Parts Discussed in Thread: SYSCONFIG

Hi team,

Here's the reply from the customer:

The project supports 4 device connections, 2 masters and 2 slaves. When the CC2642 is used as the master and connected to one device, two mobile phones alternately connect to the CC2642.

After repeated times, it is found that when calling the GATT_Notification to send data to the mobile phone, the data cannot be sent and returns 0x16. (1 time per second, no recovery for more than 1 minute). The connection interval is 30ms, and both Apple and Android phones have this problem.

SDK: simplelink_cc13x2_26x2_sdk_5_10_00_48

Mobile phone model: Apple 13, Huawei P30 PRO

MAX_NUM_PDU is changed from 100 to 250, and the customer stack is changed from 10k to 20k. The phenomenon is the same.

After this problem occurs, it cannot be recovered without disconnecting the connection, no matter how long to wait. After this problem occurs, when the master calls GATT_WriteNoRsp to send data to the slave, it also returns 0x16. Memory is still enough.

The fault time point is 2023-05-25 15:20:05.361

Can you please check this case?

Hi Nick,

When GATT_Notification() returns 0x16 (blePending) it means the GATT operation could not occur, generally because the queue of GATT operation is full. The queue may be full because the GATT operations are not executed fast enough compared to the pace they are enqueued (see https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1197903/launchxl-cc26x2r1-notification-returning-0x16).

In your case, as the CC2642R forms 4 connections (and 2 of those are peripheral connections), and as the issue is only rarely reproduced, the issue might be caused by the timing of the connections. Said differently, in certain cases, the connection operations may overlap, and some of the operations have to be dropped. As a consequence, the connection has less opportunities to empty the GATT queue and you end up with the behavior described.
In order to identify whether this is the root cause, you can enable the RF observable (or use a Bluetooth sniffer) to see if some RF operations are dropped in certain cases.

In case, the root cause I describe appears to be the actual root cause of your issue, I am afraid the best workaround will be to close the connection whenever the problem is detected (i.e. whenever the function GATT_Notification returns 0x16 a couple of consecutive times) and re-establish it later.

I hope this will help,

Best regards,

Hi Clément,

Thanks for your quick and helpfui reply. Here's the further reply from customer:

When this issue occurred, four devices were not connected simultaneously. Connected a device in master mode. In slave mode, two mobile phones are connected interactively, not simultaneously, which means only two devices will be connected at the same time. You said "delete certain operations" or "clear GATT queue". Is there a relevant interface to operate this, such as clearing when there is a problem?

What's more, MAX_ NUM_ PDU of queue has now increased to 250, and the frequency of sending data from both devices is at the second level, so the probability of the queue being full is not high.

Thanks and Regards,

Nick

Hi Nick,

You are welcome.

I am not sure where I suggested to "delete certain operations" or "clear GATT queue". But, if you want to do this, you have to terminate the connection.

It would be interesting to ask the customer how they set-up the MAX_NUM_PDU value and verify it is properly done. In addition, you may want to double check the MAX_PDU_SIZE is set to a value matching the system's requirements. Note that both MAX_NUM_PDU and MAX_PDU_SIZE are meant to be setup using SysConfig.

I hope this will help,

Best regards,
