CC1101: Related issues of the CC1101 communication

Dear expect:

      One of my customer met some issue when using the CC1101, so could you help to locate the root cause? Thanks!

      1. The speed of sending and receiving data by SPI is 37kbps, which is far from 250K of cc1101

       2. At the same time, each 61 byte data requires some delay, otherwise in the case of continuous data transmission, the next packet will fail to receive and receive.

        Schematic was attached below;
