To bring the device into configuration mode, in this case press Reset_Button 2 times
When in configuration mode, the device goes into Access Point mode.

In order to enter or change the settings, you need to:

- Sign in at https://cloud.supla.org (registration is free of charge)
- Connect to WiFi called "Supla_MPR121” from any computer with a wireless network card and Internet browser.
- Open access page: http://192.168.4.1
- Enter user name and password to the WiFi through which the device will get Internet access.
- Enter Server address, Location ID and Location Password, which will be provided once you sign in at cloud.supla.org

Of course it's works perfectly :). I'm making a mistake somewhere.
My wemos d1 goes not to accesspoint mode after i press reset button 2 times, it blinks every 2 seconds. I have tested with other wemos, same problem. I have checked wirings and not see any error. In arduino serial monitor it prints following:

clearly describes Mpr121 not found.
what model of Mpr121 you are using, maybe an image of the module.

Yes, ADD is with GND 0 Ohm.
Can the wemos go to access point mode without attachting to mpr21 and mcp23017?
