Part Number: CC2642R-Q1

Hello Team,

CC2642 SDK version: 6.40

Use mobile connect, Write and notification data once per second,after a period of time, ATT Write Transaction not response

What may be the reason for this? Do you need to catch any logs.

    Hi Jahn Jahn,

    Can you test the latest SDK (SDK v7.10)?

    When this occurs, do the devices eventually disconnect due to an ATT timeout or is the connection maintained?

    Is the TI device in the peripheral role?

    Who is initiating the GATT write request, phone or TI device?

    Can you please attach your full Ellisys log as well. 


    Is this reproduced on the out of box software with just a few changes, or is this on your full application software? Would be great if you had a short code example that you could share that reproduces this, if available.

    Hi Evan,

    I'm sorry I couldn't test sdk 7.10 because the application has been mass-produced

    The devices is the connection maintained,but application will disconnect timeout 5s.

    Phone initiating the GATT write request.

    Please provide a path to upload sniffer log because the log is a bit large.

    Thanks.
