ZIGBEE SDK ZB_GET_OUT_BUF_DELAYED2 call failed

[xjhu]

HI,all

I am a newman for zigbee on NRF52840 with S140 softdevice,

I have two board, one is ZC and another is ZED.

On ZC board, I use ZB_GET_OUT_BUF_DELAYED2 to send data to ZED continuely,about 100 times this method return failed and can not alloc a buf.

after about 3 seconds ZB_GET_OUT_BUF_DELAYED2 can be called successfully.

My question is:

1,when ZB_GET_OUT_BUF_DELAYED2 call failed, is there any method to relase or remalloc buffer?

2,how to reduce the time(about 3 seconds) to get new buf successfully?

3,why need wait for some seconds to get new buf?

wish your help,thanks.

Hi.

If you look at the file components\zigbee\cli\zigbee_cli_cmd_generic_cmd.c

Can you change:

ZB_ZCL_PACKET_PUT_DATA_N(ptr, cmd_data, cmd_size); \

To:

/* Scan argument with payload and put in buffer with command to send */

for (zb_uint8_t i = 0; i < p_cmd_query->payload_length; i++)

{

ZB_ZCL_PACKET_PUT_DATA8(ptr, (p_cmd_query->payload[i]));

}

If you want to disable acknowledgement, please remove:

ZB_ZCL_FINISH_PACKET(buffer, ptr) \

 

Add this define at the top.:

#define ZB_ZCL_FINISH_PACKET_NO_APS_ACK(zbbuf, ptr) (void) zb_zcl_finish_and_send_packet_no_ack((zbbuf), (ptr),

And change:

ZB_ZCL_FINISH_PACKET(buffer, ptr) \

to

ZB_ZCL_FINISH_PACKET_NO_APS_ACK(zbbuf, ptr) \

Best regards,

Andreas
