IAP_LEN長度是200 使用這一串?dāng)?shù)組進(jìn)行編程燒錄無法進(jìn)行下一次藍(lán)牙數(shù)據(jù)通信，但是任意改變0x23字符為0x00 數(shù)據(jù)就能正常傳輸

我找了下，我們OTA的代碼里面沒有這個數(shù)組的定義。

你是在哪個工程上測試的，具體說一下，我們測一下問題。

這個是我們網(wǎng)關(guān)的代碼 就是發(fā)OTA固件的內(nèi)容給CH582M? 目前發(fā)現(xiàn)有些內(nèi)容可以正常收發(fā) 但是例如上面一串?dāng)?shù)據(jù)就會出現(xiàn)異常，剛剛看到一個論壇問題 關(guān)于582M OTA內(nèi)存只有16K問題，不知道是否有影響，我們582M OTA是否嘗試使用過200K左右的固件大小測試過。

嗯，ld文件是錯了

按照這個吧ld文件改了，再試試。

把主機(jī)的數(shù)據(jù)長度改為84就不會出問題了，具體原因還是不是很清楚。長度改200? 自己隨便丟一串字符串是不會出現(xiàn)通訊失敗，但是遇到這個固件特殊字符串就會掛。
