Question: Timeout while updating firmware

[archie94]

On certain device when we try to update device firmware we get a timeout with the following

ERROR msg = Transaction 67 timed out without receiving a response

Generally a bluetooth toggle and retry fixes it.

What can be the issue here?

@philips77 do you have any idea on this one?

Hi, Sorry for the late response. I must have missed the question. It may be, that some recent changes improved the situation. Did you try versions 2.0.x? Also, you may decrease number of buffers used using smaller windows capacity. Setting it to 1 will make the library always await notification before sending a new packet, making upload slower, but this issue should never happen. But you may try with value 2 or 3.
