:) And here is the checkOK function as well... I'm in a rush. Let me
know, if you need more assistance. It's probably better I send you the
whole .py :)
def checkOK(buffer):
sum = 0
for c in buffer[1:]:
if (c == "*"):
break
sum = sum ^ ord(c)
try:
cs = buffer.split("*")
packet_sum = "0x"+cs[1].lower().rstrip()
return packet_sum == hex(sum)
except:
return False
