docs/smpp-ota-tool: Add documentation/tutorial

We already have documentation that explains how to run pySim-smpp2sim. With smpp-ota-tool we now have a counterpart for pySim-smpp2sim, so let's add documentation for this tool as well. Related: SYS#7881 Change-Id: If0d18a263f5a6dc035b90f5c5c6a942d46bbba49

Philipp Maier	af21005c94	contrib/smpp-ota-tool: define commandline arguments in global scope The commandline arguments are currently defined under __main__ in a private scope. From there they are not reachable to the sphinx argparse module. We have to define the arguments globally at the top. (like in the other applications) Related: SYS#7881 Change-Id: I2d9782e3f5b1cac78c22d206fdcac4118c7d5e7c	2026-03-06 10:41:13 +01:00
Philipp Maier	ea3b9937e5	contrib/smpp-ota-tool: use '-' instead of '_' in command line args Some commandline arguments have an underscore in their name. Let's replace those with dashes. Change-Id: Icbe9d753d59263997e9ca34d46ed0daca36ca16c Related: SYS#6868	2026-03-06 10:41:13 +01:00

Philipp Maier	2d5e20e342	tests/pySim-smpp2sim_test: add testcases for AES128 and AES256 Extend the existing test script so that it can handle multiple testcases. Also add support for switching eUICC profiles. Finally, add a testcases to test OTA-SMS (RFM) with AES128 and AES256 encryption.
