Why does the read Attribute return zero?

qingshuzhuang — Sat, 09 Mar 2019 07:28:37 GMT

When i read u48CurrentSummationDelivered attribute of Simple Metering Cluster, the return value is zero.

When i read u8MeterStatus attribute of Simple Metering Cluster, the return value is right.

So I think the problem is that I can't read attributes that are larger than 4 bytes in size.

Is there any way to solve this problem?

There is my code：

Base on project “JN-AN-1218-Zigbee-3-0-Light-Bulb”

Init variables

Hi,

The return value that you are getting is correct, as you know the node is sending the attribute response with and the data byte list: stream of uint8_t
