根据文档 以下步骤做操作:
WiFi and Ap mode on R2 Ubuntu
AP mode

  • wmt_loader (ignore errors)
  • stp_uart_launcher -p /etc/firmware &;
  • echo A >/dev/wmtWifi
  • create your hostapd.conf: "vim /etc/hostapd/hostapd.conf "
    执行stp_uart_launcher -p /etc/firmware &时提示错误如下:
    Can’t open device node(/dev/stpwmt) error:-1
    请问这是什么问题?
