Hello,
I encountered what appears to be a bug when using application ports to handle downlinks.
I use the application port in a switch-case statement in my downlink handler. I am sending downlinks like so
I am using port 2 for my uplinks and downlinks.
My log says this
As you can see, it hits both port == 2 and port == 5 cases.
Here is my downlink handler
Any help is appreciated!
Using if-else if statements work.
So it just the switch-case statement that is at fault.
Port is a uint8_t variable, I assumed that the switch-case statement supported it.
It’s a problem inherent in C-style case statements. They fall through to the next case (it’s a feature) unless you end with a break;
Please put in some break statements at the end of each case block.
To make it complete a skeleton for a ‘proper’ switch … notice the breaks and the default:
switch (expression)
{
case constant1:
// statements
break;
case constant2:
// statements
break;
.
.
.
default:
// default statements
}
Doh! I forgot. Thanks guys
