How to implement a simple zigbee cluster that tow-way data transfer between zigbee coordinator and device?

Hi,

I want to implement a simple Zigbee cluster that can transfer bytes between zc or zd, like UART TXRX.

I found Messaging Cluster might be the one. After checking these posts below, I still do not have an idea of how to implement it in Zigbee Template example.

I am aware that there are some libs that seem to have been implemented.

ncs\v2.1.0\nrfxlib\zboss\production\include\zcl\zb_zcl_messaging.h

ncs\v2.1.0\nrfxlib\zboss\production\src\zcl\zcl_c_messaging.c

ncs\v2.1.0\nrfxlib\zboss\production\src\zcl\zcl_s_messaging.c

Could you guild me on how to implement it on the Template example code and use the Shell example ad zc to send and receive data from that message cluster?

many thanks

Hi

Please check out this ticket where a customer has implemented the ZCL messaging cluster, unfortunately we don't have an application using the messaging libraries in our SDK yet. The ZBOSS stack and thus ZCL messaging cluster commands are identical to the commands listed in the Infocenter. How you implement these commands into your project will be up to you.

Best regards,

Simon

Hi

How to DECLARE cluster and EP for messaging cluster?

I have checked those posts that did not mention it.

many thanks
