Hello,

I'm trying to connect AmazonEcho using LE Secure Connection.

When ATT_MTU_UPDATED_EVENT received,GATT_ExchangeMTU() returns SUCCESS only when MTU size = 65.(If MTU size is other value, that returns Invalid Parameter)

After that, GATT_DiscAllPrimaryServices is called after ATT_READ_BY_GRP_TYPE_RSP is received.

Then, After the moment ATT_READ_BY_GRP_TYPE_RSP is received, HCI_DATA_BUFFER_OVERFLOW_EVENT is occurred.

Could you tell me how to modify HCI DATA BUFFER?

Is it relative to MTU size?

I would like to procedure to fix it.

Regards,

Hi U-SK,

I have assigned an expert to help you on your question.

In the meantime, I had a few clarification questions:

- Which SDK version are you using?

- Which example project are you using to test?

Best Regards,

Jenny

Hi U-SK,

Try going into the ICALLBLE folder in your project, and in the ble_user_config.h file, increase the MAX_NUM_PDU value. I believe this may solve your issue. Please let me know if it persists.

Best Regards,
