不服也得服,BBGW叫板RPI3——BeagleBone Green Wireless評(píng)測(cè)

seeed   BBG   RPI3   BeagleBone   Wireless   BLE

  • RPI3才出來(lái)沒(méi)多久,又遭到seeed的追虐。BBGW也是Beablebone系列中首款支持內(nèi)建(Built-in)Wi-Fi(MIMO技術(shù))和BLE(4.1 LE)的開(kāi)發(fā)板。

嗯,這個(gè)easy, easy。一個(gè)SoftAP0, 一個(gè)usb0,一個(gè)wlan0,分別對(duì)應(yīng)的IP為:192.168.8.1,192.168.7.2,192.168.2.104。確實(shí)有3個(gè)IP地址。解決了這個(gè)問(wèn)題,再用route命令來(lái)查看路由設(shè)置

這下不用擔(dān)心學(xué)無(wú)所用了吧,很明顯,wlan0負(fù)責(zé)處理192.168.2.0/24及192.168.8.0/24的所有路由轉(zhuǎn)發(fā),而usb0則負(fù)責(zé)所有192.168.7.0/24的路由轉(zhuǎn)發(fā)!

如果沒(méi)看懂,騷年,補(bǔ)補(bǔ)網(wǎng)絡(luò)基礎(chǔ)知識(shí)吧!

然而還有BLE,咱也體驗(yàn)一下。準(zhǔn)備小藍(lán)牙音箱一個(gè)
