Hi all, I'm making some mods to the Z-Stack example GenericApp, and there are a couple of things that don't make sense to me. 1. In the system event processing code, there is a MSGpkt variable of type afIncomingMSGPacket_t that passes in system events. I would like to know the RSSI value associated with messages moving between an end device and the coordinator. I thought that this could best be achieved by sending some kind of Zigbee level request to the coordinator, and then acting on the response callback and analysing the afIncomingMSGPacket_t packet structure, i.e. case ZDO_CB_MSG nwkRSSI = MSGpkt->rssi This always gives nwkRSSI = 0x00 Whereas if I send an application level message to the end device, this does seem to work, i.e. case AF_INCOMING_MSG_CMD nwkRSSI = MSGpkt->rssi This always gives what looks to be a plausible value for the RSSI. I'm curious to know why there is a difference, and also whether there is a better way to get the RSSI.
