Keep in mind Lora is not LoRaWAN and however excellent the book, supporting multiple chipsets is still a lot of work that is not necessarily worth the trouble.
The good news regarding LoRaWAN is that a component for EU868 frequencies should be available soon. (A couple of months)

Your request to support all Lora modules regardless of brand is not realistic imho. There are too many out there and as I mentioned, documentation is an issue for most of them. Supporting all would require one person full time work and that is not an option for the current (small) team. Of course if...

Lora modules are complex and documentation is scarce to non existent. Also timing is critical so implementing components that work well on all controllers is a major investment in time. There is a LoRaWAN component in development. BTW, if you search the internet a bit you will find Lora modules that...

Probably a stupid question but what is the power up state of the LED? Is it not lit if you use a flowchart that doesn’t have any macros related to it? (So an empty flowchart with just a loop doing nothing)

To see the cost you go to flowcode.co.uk website and look at the top for “Buy Flowcode”. Click there. Payment options will be listed.

If you need to send quotes within a string you can use a backslash to escape it,

So your correct command translates to “AT+PSWD=\”6789\”” in the expression box.

This error is not license related. Check the chip settings in your flowchart and disable the extended instruction set.
