Hi Renzo,
First of all, thanks a lot for the library you created, much appreciated!
Finally I got working my E220-900T30D modules with WeMos D1 mini board, but some things are not so clear yet:
1. I try to configure it to use 868 MHz by adding#define FREQUENCY_868, but when I read configuration – it shows 433MHz. Please, can you provide a snippet of code that will turn 868 MHz frequency ON. I’ve tried setting channel to 18 (assuming formula 850+CHAN*1M), but no luck, looks like it uses 428 MHz instead, because I just stop receiving data.
2. Should I connect M0 and M1 and disconnect AUX for saving configuration, or I can use same wiring as for “normal operation”?
3. Configuration should be saved just once or every time on microcontroller boot?Thanks!

Hi Vilin
you must put#define FREQUENCY_868before the include of the library. If It does not work, add directly to thestatesNaming.hfile.
In my library, I allow connecting
Rx, Tx or Rx, Tx, AUX or Rx, Tx, AUX, M0, M1
AUX is quite important for performance (without AUX, I add the maximum delay to be sure the operation was complete).
You can save the configuration permanently or only for the session.You can find more information here
