CC2340R5: Receive APS payload

Shuyang Zhong

Part Number: CC2340R5

Tool/software:

I am trying to receive APS raw data in ZBOSS. I have followed the SimpleLink Academy to send the APS raw data from on_off_switch, and has confirmed the APS data was sent successfully through sniffer log.

On the receiver side, I tried to use zb_aps_get_aps_payload() in zcl_specific_cluster_cmd_handler to retrive the APS payload, however the returned buffer and size did not seem right. The sent payload size was 12, but the returned size was only 4, and the data buffer only contained the last 4 bytes:

Is this an issue in the stack, or am I not using it right?

Best regards,

Shuyang

Here's my code to received the APS data:

Hi Shuyang,

The API you are using appears to be out of context within the command handler it is used within. Can you try using the more general zb_buf_begin and zb_buf_len functions instead? If you set the size and buffer variables as globals, outside of zcl_specific_cluster_cmd_handler, then they may be viewable by your CCS debugger.

Regards,
Ryan

Hi Ryan,

zb_buf_begin and zb_buf_len do work, thanks.

What is the proper context for zb_aps_get_aps_payload()? Is it only useful at the Tx side?

Best regards,

Shuyang

It's difficult to discern without further investigating. It's not about the TX side, rather the callback context. The only reference I can find for zb_aps_get_aps_payload is when it is used for a callback set using zb_af_set_data_indication, which is different from the zcl_specific_cluster_cmd_handler configured with ZB_AF_SET_ENDPOINT_HANDLER. I'm glad to hear that you have a solution which does meet your needs.

Regards,
Ryan
