Sorry I haven't gotten back to you, been a busy week.
The MY_TRANSPORT_MAX_TX_FAILURES seems to do the job perfectly, I adjusted it down to 1 for the node, and resend the message a couple of times if it fails.
Thank you for your support
Also thanks to berkseo, your code also works for me, but I do prefer the built in way now that I know of it. Less code for me to write and maintain
