MTU没毛病的 ，要在订阅读写后，去申请完毕再 读写数据

一般在连接成功不能立马setMtu 或者立马 write 。 ble连接成功建立通信后要加个短暂的delay在setMtu或者write，不然会102。

A pause after detecting the device and connecting solves problem 102

I met the same question; when I unbind a ble device, then try rebind to it; tips: 'wreite writeCharacteristic fai'; what should I do
