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”
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
