How to handle E_ZCL_ERR_ZTRANSMIT_FAIL status return?

baskoevoets — Fri, 05 May 2017 09:55:50 GMT

I have an application running on my main processor that talks to the Zigbee firmware running on the ZigBee chip (in this case JN5169).

Whenever I send a command to a device that is offline, I stop when I receive the 0x8702 reply (APS Data Confirm Fail).

However, when I now try to send a new command (to the same or a different device), I receive a status message (0x8000) with error code 0x15 (E_ZCL_ERR_ZTRANSMIT_FAIL).

It now takes several seconds before I can send again.

How should I handle E_ZCL_ERR_ZTRANSMIT_FAIL?

Is there a better solution to handle this issue than to wait until I can send again?

I am using using JN-AN-1223 with JN-SW-4168 v1470

Hi,

This authentication interval must be set on all potential parent nodes via the network parameter APS Security Timeout Period

10.7 Advanced Device Parameters

APS Inter-frame Delay

Number of milliseconds between APS data frames. Following transmission of each data block, the APS starts a timer. If there are more unacknowledged blocks to send in the current transmission window then, after a delay of apsInterframeDelay milliseconds the next block is passed to the NWK data service. Otherwise, the timer is set to apscAckWaitDuration seconds.

Hope it helps.
