C33 switch WiFi mode - Githubissues

It seems it's not posible to switch from WiFi client mode to WiFi AP mode. To reproduce, I took the AP_SimpleWebServer example, and added a call to WiFi.scanNetworks() before the WiFi.beginAP() :
/*
  WiFi Web Server LED Blink

  A simple web server that lets you blink an LED via the web.
  This sketch will create a new access point (with no password).
  It will then launch a new server and print out the IP address
  to the Serial Monitor. From there, you can open that address in a web browser
  to turn on and off the LED on pin 13.

  If the IP address of your board is yourAddress:
    http://yourAddress/H turns the LED on
    http://yourAddress/L turns it off

Same problem : if I connect to a wifi, then want to switch to AP mode, it's not possible to connect to the access point (the IP configured with WiFi.config() is not used, the phone cannot connect to the AP)
