CheckMac 可以印出Ameba8195的mac位址
ChackAP 可以連接附近的AP
ScanNetworks 可以掃描附近可以連接的AP
不過當USB斷線時，連接AP的狀態也會斷掉
在ScanNetworks裡面看到RSSI，查了資料以後發現在 wifi 和 802.11兩個關鍵字當中是個重要的參數呢
以下為資料節錄

From Metageek
What is RSSI and what does it mean for a WiFi network?
- RSSI, or “Received Signal Strength Indicator”, is a measurement of how well your device can hear a signal from an access point or router. It’s a value that is useful for determining if you have enough signal to get a good wireless connection.
- Note: Because an RSSI value is pulled from the client device’s WiFi card (hence “received” signal strength), it is not the same as transmit power from a router or AP.
From WIKI
- the higher the RSSI number, the stronger the signal. Thus, when an RSSI value is represented in a negative form (e.g. −100), the closer the value is to 0, the stronger the received signal has been.
