Understanding ZclAttrRead flow

[Osendo]

Hi. I'm new to the zigbee stack, I'm having some trouble with a request to read an attribute from a RTCGQ11LM sensor. Maybe I don't understand the request path correctly, in that case please correct me. Example request:

uint16_t au16AttrList[1] = {0x0000};
zbhci_ZclAttrRead(0x03, (ts_DstAddr) {.u64DstAddr = deviceList[i].u64IeeeAddr}, 1, 1, 0, 0x0406, 1, au16AttrList);

I expect a message to come from the sensor after this with u16MsgType == ZBHCI_CMD_ZCL_ATTR_READ_RSP

You can try to wake it up by pressing the button of RTCGQ11LM within 0-7 seconds after sending zbhci_ZclAttrRead.

ps: The RTCGQ11LM sensor is a dormant device, it is only active for one minute after joining the network.

As I understand it, I got a response from the device that it accepted the read request, but nothing happened :) The device is alive and sends data when a key is pressed or movement
