CC2540EMK-USB: BTool Establish link fails intermittently with (Message Is Missing Bytes to Process)

I have (had) been successfully using BTool v1.41.16  for OAD testing for several days. I don't think I changed anything, but started fighting a failure to establish a link with BTool for several hours, so I started to write this post.

The error was:  

--------------------------------------------------------------------

[10] : <Error> - 10:48:00.002
Could Not Convert All The Data In The Following Message
(Message Is Missing Data Bytes To Process)
--------------------------------------------------------------------

In order to provide a clean log, I cleared the log, (re)scanned, (re)established a link, but Establish Link succeeded.

Today it failed again. Clearing the log is not helping...

Any clues for the clueless.

    Hello Scott,

    I've notified our BTool development team with the log and will update when I hear back.

    Best wishes

    Hi,

    The latest BLE stack uses BTool v1.41.17. Do you have another CC2640R2F LaunchPad that you can flash HostTest project to use with BTOOL instead of the CC2540 dongle?

    Here is the User Guide (after downloading the SDK) for using the latest BTOOL:
    file:///C:/ti/simplelink_cc2640r2_sdk_1_30_00_25/docs/blestack/btool_user_guide/BTool_Users_Guide/index.html#creating-a-connection-between-the-cc2640r2f-launchpad-and-a-peripheral-device

    Best wishes
