I return to this comment: an error in my program is the cause of non-operation (a '=' instead of '&' in the macro #define IO_LEVEL) so it is not the module that is in question - sorry for this error on my part. With the corrected program - everything is OK.
Alas, does not work - checked and rechecked the connections - used several versions of the program (and verified includes) At this price, it does not matter. Maybe the chip is HS - I ordered another module (not the same -) to confirm this ... Stay tuned.
