I have tried to use the 'HA_ON_OFF_LIGHT" example code (unaltered in all key aspects) to connect to my "Home Assistant" system that has a SkyConnect Zigbee coordinator.
Everything works at first (and I can toggle the light on and off on the DevKit with the 'switch' that the Home Assistant 'device' provides) but then I start to get the "NLME Status Indication - Status 0" messages and I can't find that they mean.
Shortly after each, the SDK seems to restart and successfully rejoins the network, but eventually it wil fail to initialise the zigbe stack and then tells me the device is unavailable.
According to the Home Assistant device, the RSSI is about -42 which should mean a good connection.
How do I start to go about identifying what is the problem as the documentation simply lists the ESP_ZB_NLME_STATUS_INDICATION as an enumerated value (which is obvious) but does not say how to interpret the status code (if it is a Zigbee NWK status then it is 'no path'!).
The log from the devkit is below.
