Hello,
This is a question about Ra-08H Development Kit, used with "AT" firmware announced as "+CGMR=release/v1.3.4 LoRaWAN for US915".
MY QUESTION: is it possible to access the GPIO pins with this firmware in order, for example, to turn ON and then turn OFF the LEDs on the Development Kit?
WHAT I HAVE FOUND SO FAR MYSELF: I have spent the last night searching the internet and I was not able to find much:
- Nothing mentioned in the document with the "AT" commands v0.1.0 from 2022-03-20 -- no "AT" commands found in the document, which can set or get the status of the GPIO pins on the Development Board.
- And nothing in the Ra-08H-Kit Specification V1.2.0 from 2022-03-02 -- nothing to explain how to do it with "AT" commands.
- Finally, nothing in a document called Ra-08(H) secondary development GPIO Pin Description gpio_function_mux_table_1010.pdf.

Now I think that it is not possible to access (to set or to get the status of) GPIO pins of the Development Kit with "AT" commands firmare. But is it possible in some other way to do this, especially: is it possible to do this still preserving the "AT" firmware? Or have I missed something obvious to all others last night? Please help.
And if it is not possible to do this with "AT" commands firmware, then what firmware would you recommend to use in order to do this and still to be able to use all LoRaWAN functions?
And last, but not least question: is there a firmware or other program code that can be loaded into Ra08H from Arduino IDE? From what I have seen on the internet this does not appear to be possible (namely, it has not been doneand reported, I am sure that a knowledgeable person with a lot of time would be able to develop an abstraction and an adaptation layer for Arduino IDE, but I was unable to find anything last night on all Arduino forums, with the exception of an advice to use the "AT" commands set by sending them from an Arduino-compatible board, e.g. by sending them from ESP32).

All advice will be greatly appreciated.
This is my first post on this here forum, apologies if I did something not right, thanks for your good humour.
