invalid conversion from ‘unsigned char*‘ to ‘const jbyte* {aka const signed char*}‘

jni遇到invalid conversion from ‘unsigned char*’ to 'const jbyte* {aka const signed char*}'错误
不支持格式之间的转换
错误的栗子：EEP_Buffer C++中的数组

	uint8_t  i;
    FixDirectFunc(Type, PulseWidth, Data, KeyNum); //C中的函数
    jbyteArray iarr = env->NewByteArray(188);
	env->SetByteArrayRegion(iarr,0,188,EEP_Buffer);
    return iarr;

正确的栗子：

	uint8_t  i;
    jbyte res[188];
    FixDirectFunc(Type, PulseWidth, Data, KeyNum);
    for(i=0;i<188;i++){
        res[i] = EEP_Buffer[i];
    }
    jbyteArray iarr = env->NewByteArray(188);
	env->SetByteArrayRegion(iarr,0,188,res);
    return iarr;
