Microchip dsPIC33FJ系列都不能用MCC生成底层代码吗？我这要配置dsPIC33FJ32MC204，发现不能使用MCC。同时试了下dsPIC33FJ的其他型号，也是不行。

SDK版本是simplelink_cc13x2_26x2_sdk_4_30_00_54。在例程simle_peripheral上进行的修改. 通过GATT_Notification函数操作特征值4.通过sysconfig把 MAX_PDU_SIZE 修改为255.在周期性任务中调用了一次HCI_LE_SetDataLenCmd(connList[0].connHandle,251,2120)。但是还是不能一次性传输超过20个字节。请问该怎么做才能实现超过20个字节的发送呢？谢谢。
