終於能夠了,8266AT指令版本,實現遠程升級單片機程序....主要問題是兩個printf離得太近,wifi當成一個數據了測試

先說明一下,若是本身不是用的8266應該修改的地方,因爲只是IAP程序裏面實現的升級,因此只須要修改IAP程序就能夠,你們能夠在用戶程序裏面實現本身的具體功能,若是想升級,就復位一下單片機就能夠spa

其實程序和上一版並無太大改動...連解析協議都沒動,只是修改連接TCP的函數而已3d

還有個地方須要注意:http數據解析的地方code

我如今用的是8266透傳實現的,也就是說,網絡回給8266什麼數據,8266就發給單片機什麼數據,不摻雜任何其餘東西

若是本身的模塊回覆的整個數據是這樣也能夠

XXXXXX http數據 http數據 http數據

這樣的不能夠

XXXXXX http數據 XXXX http數據 XXXX http數據

須要在這裏剔除,...算了,我再作一版.....下一節吧

這是個人數據解析部分

如今看使用

1,給Wi-Fi刷AT指令的固件.依照本身的模塊選擇

2,下載單片機程序(先看一下後面的說明再下載)

由於WIFI須要聯網,程序默認加入了SmartConfig配網

能夠先運行APP的配網,而後按下這個按鈕

配網APP直接用,就能夠,也支持微信配網
