CC2530: 有关zigbee协调器在一次接收数据中的字节数最大为多少

Qiang Huang

Part Number: CC2530
Other Parts Discussed in Thread: CC2650, Z-STACK

目前以cc2650为zigbee终端节点，发送50字节的数据到协调器cc2530

协调器CC2530接收50字节数据并以uart传输至电脑

电脑的串口可以接收到数据。

但是当cc2650要发送100字节数据时，电脑串口并不能收到数据。

请问是否是接收数据量过大导致？接收数据的字节数最大为多少？

请问zigbee协调器接收数据量大小是否是自己配置的？怎么修改配置文件？

    您好，

    收到工程师的回复：

    Can the customer please clarify whether the larger data packet is being sent out over the air, and whether it is fragmented (i.e. separated into multiple smaller packets)? I assume Z-Stack HA 1.2.2a is being used since the CC2650 is involved. They should review the OnBoard.h MT_UART_RX_BUFF_MAX/HAL_UART_RX_BUF_SIZE as well as _hal_uart_dma.c HAL_UART_DMA_RX_MAX.  Non-UART definitions to consider include MAX_BUFFER_SIZE and MAX_TRANSFER_SIZE from the ZDConfig.h file.  Keep in mind that increase buffer sizes will further constrain the limited RAM on CC2530 devices.

    您能否说明较大的数据包是否通过空中（over the air）发送，是否分段（即分成多个较小的数据包）？由于涉及 CC2650，我假设正在使用 Z-Stack HA 1.2.2a。他们应该查看 OnBoard.h   MT_UART_RX_BUFF_MAX/HAL_UART_RX_BUF_SIZE 以及 _hal_uart_dma.c   HAL_UART_DMA_RX_MAX。要考虑的Non-UART 定义包括 ZDConfig.h   文件中的 MAX_BUFFER_SIZE 和 MAX_TRANSFER_SIZE。请记住，增加缓冲区大小将进一步限制CC2530 设备上有限的 RAM。
