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?
