MSP430FR2476: Does MSP430FR2xxx BSL have timeout feature?

Does the BSL mentioned in title have a timeout feature between messages? I noticed if I send them back to back the BSL responds and if I send them with large time delays between messages the BSL hangs.

I'm referring to messages like unlock, rx block etc...

I can't seem to find any mention of this in the BSL users guide, but I'm seeing this behavior.

I may have actually had this backwards - I think sending command messages too close together is the issue.

I don't know. You might try a test run using BSL Scripter with the same command sequence to see if the errors go away.

The BSL on the FR26xx, FR25xx, FR24xx, and FR23xx MCUs implements a low-power time-out feature
for the automatic detection of the BSL interface. If no communication has been established within ten
seconds, the device enters LPM4 mode. To invoke the BSL again, the device power must be cycled, or a
reset or NMI must be received.
