It seems the comment for GetDevAddress was copied from GetUniqueId, but not changend sufficiently to be correct.
These warnings are caused because frequencies are stored as `uint32_t`, which is `unsigned long`, while the printf format expects `int`. In practice, this does not actually cause problems, since on STM32 gcc `long` and `int` are both 32-bits and frequencies are never large enough to cause signed vs unsigned ambiguity. Since printf has no format specifiers for e.g. uint32_t (libc does have some macros for this, but those really hurt readability), this is tricky to fix in a portable way (other architectures or compilers might have `uint32_t` equal to `unsigned int` instead of `unsigned long`), this fix just casts the frequency to `unsigned` before passing it to printf (and for good measure, also convert the specifier from `%d` to `%u`). This does mean this printing will break if `int` is not at least 32-bits (e.g. on AVR), but given the scope of this library, that should be acceptable.
This adds some more details about RX and TX bytes and TX config. There is also some code for RX config, but to minimize the impact on RX timing, that is commented out.

While developing the STM32LoRaWAN Arduino library, which includes a part of the code from this repository, I made a couple of small changes to it, to fix warnings, documentation and ease debugging.
I've included these changes in this pull request. They are essentially three independent changes, put into separate commits. If needed, I can split them out into separate pull requests, but I thought it might be better to first show these and let you consider if you want to include any or all of them at all before I go to that additional effort.
This is a resubmit of #57, but I confirmed permission to submit this contribution from my contact at ST, so I now signed the individual CLA.
