Banana M3 - WiFi and BT problem

Hi Banana Fans,

I bought used Banana PI M3 this week. Yesterday I installed below OS’s from website:

  • Raspbian Lite
  • Kano
  • Ubuntu minimal

I have a problem with WiFi and Bluetooth in all three OS :

  • I am able to see WLAN interface (ifconfig/iwconfig) but I am not able to see any Wireless network during scan
  • I am not able to see (hcitool scan) any bluetooth devices (I tested with BT keyboard, BT speakers, notebook and smartphone)

Do you have any advice? The reason of problem could be related with hardware or software?

What should I do? Should I return this Banana Pi M3 and buy another one? Or install another OS?
