如果每个芯片有 unique chip id 的话, 就可以解决:
App OTA 之前, save chip id->mac pair, after OTA 之后, scan->new mac->read chip id,
然后 either 更新 App, 或 chip 重写 old mac ( bt_mac_addr_set )

确认isd_config.ini文件的BTIF_OPT=0;等于0会擦掉蓝牙地址。或者0.7.1和0.5的sdk存储结构略有区别也会出现btif区域位置变化导致原来的数据丢失。确认下0.7.1是否升级0.7.1就不会有这个现象。

我這邊驗證了0.7版本的後面升級的沒有出現這個問題。
我擔心的是
0.7版本的升級到以後比如0.8版本的還會不會出現同樣的問題?比如說我做好了0.7的發送到客戶手上如果升級0.8出現這個問題客戶升級後產品就變成磚頭了,要寄回才能修了。

我這邊需要怎麼設計才能避免這個問題?
