mergBLE usage

[Brian Milby]

I’m guessing you have a card that when you open it will initiate a look for
available connections. You have the appropriate handlers in place that work
if one is found. Now you want the card to not wait forever though?

If that is the case, there are a couple threads on the forum that may help:

When you initialize the card, you need to start a process that checks for
an active connection. If time runs out before a connection is made then
call the exception routine. If a connection is made, cancel the check
process. Here is an example from the other threads:

(Not exact since in that case a device had already been discovered and it
was waiting on a reply message.)
