I bought some 433Mhz / 1W E32 modules, at two different times.
The new ones, for some reason, cause the controller to crash, unlike the previous ones that work perfectly, I tested them in different ways and on different boards, nothing makes them work.
I used the example codes from the library itself and I can’t get it to work, all of this when connected to the ESP32, because when I connect it to the Arduino, everything works correctly.
An interesting observation is that I have an ESP32, with an identical e32 board, and everything works, I exchanged between the new E32 and the old E32, and nothing works, it seems to me that there is something with their hardware, or firmware, I don’t know. .
Attached are some images showing the difference between them, and the result of when it works and when it doesn’t.
Doing some tracing, I noticed that the problem always happens when trying to talk to the card, for example in:
e32ttl.getConfiguration(), or in e32ttl.setConfiguration()
And the status code of the board that doesn’t work is always 9, with a timeout error.
Remembering that on Arduino, this all works perfectly!
Can you help me?

I found the problem… really some difference in the new ones!
It is no longer necessary to use the pull up resistors, if I use the ESP32 it freezes, but without them it works fine.
Another point is that it is no longer possible to use an “air data rate” with value 0.3, minimum is 2.4
