Hello,
I am playing around the Zigbee samples provided by nRF Connect SDK v2.2.0.
I would like to know how to test FOTA functionality implemented in light_switch sample.
This is what I have done since today :
- Device 1: nrf52840dk with network_coordinator sample
- Device 2: nrf52840dk with light_bulb sample
- Device 3: nrf52840dk with light_switch sample
- Device 4: nrf52840 dongle configured as nRF Sniffer for 802.15.4
- Device 5: nrf52840dk configured as FOTA server.
All devices successfully created a Zigbee network and I am able to send commands by using On/Off or Level Control clusters.
What I am trying to do is to perform FOTA. After building light_switch sample I noticed that Zephyr generates the .zigbee package for FOTA in build directory, so the only thing I do to setup a FOTA server is running that command for nRF Util :
./nrfutil dfu zigbee -f 127F-0141-01020003-light_switch.zigbee -chan 16 -snr 683954443
I analyzed the frames in Wireshark and I spot that FOTA server sends a Beacon requests to join to network and after a while it successfully becomes a valid member of network. After that it sends the broadcast messages called "OTA Image Notify" to notify all OTA clusters that new image is available. The light_switch device calls the zigbee_fota_zcl_cb but unfortunately it jumps to the default case :
default:
LOG_INF("FOTA zcl cb RET_NOT_IMPLEMENTED");
device_cb_param->status = RET_NOT_IMPLEMENTED;
break;
}
As a result Zigbee FOTA procedure is not even started.
What I would like to know is :
- Is everything ok with my setup ?
- Is that way of testing FOTA ok ? or maybe there is another way to do that ?
- Is light_bulb node needed in network for testing FOTA ?
Thanks in advance,
Pawel
