Hi Rolando
Quickly skimming your code I would guess you may be getting read
timeouts in your _binary_read function.
As a first step try setting the timeout of the serial port to zero then
the read function should block indefinitely. If this is in fact the
problem a better solution would to leave the timeout in place change to
loop to iterate until you have all the data (while sizeof(output) <
size) and not for a fixed *for i in range(num_pkts): *where some
iterations are lost to timeouts.
Kind regards
