Hi, I need to write a new PDL that will strip out a start character hex <0x2> and a stop string hex <0x3> which is the last string in the message. I have the following existing code but it is not working because there may exist a message with a hex <0x3> string in the middle of the message that is not the ETX.
Does anybody have any documentation on PDL or know how I can change the following?
define phrase basic-msg;
; field data = variable-array( not(
) ); ; end phrase;
#{#
# This can be handled completely using the “basic” style.
hci_pd_msg_style basic phrase:basic-msg
field:data
resync:\xb
#}#

Barbara, I am sorry I did not read your post thoroughly.
I can see no what is probably occurring is you are getting partial messages.
In my mind the issue resides with the sending system.
I am guessing this is their encapsulation protocol and they are violating it.
Bring the issue to them and ask them to make sure ETX only ccurs at the end of the message.
