CC2530: Cluster Attribute response - Where to update attribute?

Jack Loop

Part Number: CC2530

Hi,

When my ZC sends a read attribute on my ZED's battery percent attribute, the ZED simply returns the last value back as a response. However, I want the ZED to check the battery percent, update the value, and then return the latest value back to the ZC. Where should I implement my code for the the battery percent update?

When the ZC sends read attribute on ZCL_CLUSTER_ID_GEN_POWER_CFG cluster and ATTRID_POWER_CFG_BATTERY_PERCENTAGE_REMAINING attribute, I need ZED to update the battery percent before returning response. Where should I add my battery percent update code?

I suppose you should have a periodic event to check battery level and update attribute so it will always have latest battery level in the attribute when someone wants to read battery level.

I want the battery percent to update right when the attribute is read though. Should I place the battery update code in the read attribute function?

I suppose you should put your code inside zcl_SendReadRsp.

Although not specifically for the CC2530, this SLA may be able to help you understand how to implement clusters/attributes. You can also refer to the existing examples. dev.ti.com/.../zigbee_plugin_02_custom_devices.html
