NOTES for v2.0.3 firmware
Before firmware 2.0.3, when HTTPS is enabled on the gateway, the Cassia API URL used
in the container APP should be updated to use port 443. From firmware 2.0.3, port 80
between container and gateway firmware is always enabled, so APP doesn’t need to
be updated regardless of the gateway’s HTTPS settings.
NOTES for v2.0.2 firmware
After upgrading gateway firmware to 2.0.2, if the APP uses BlueZ with Gatttool and
Bluetoothd (e.g. noble or python Bluetooth lib) instead of Cassia Bluetooth stack and
Cassia RESTful API, please change ‘Cassia Bluetooth Stack’ to close (in AC console ->
Gateway -> Config-> Bluetooth Setting, or gateway console -> Other -> Bluetooth
Setting, default is open). Otherwise, Bluetooth operations in the APP may return
failure.
Cassia Bluetooth stack and Cassia RESTful API offer the state of the art Bluetooth
scan and connection performance. It is highly recommended to keep the Cassia
Bluetooth stack open and use Cassia RESTful API to achieve the best performance
Bluetooth IoT system.
From firmware 2.0.2, an option to enable and disable container local SSH login is added
in the Container tab. The container local SSH login is OFF by default for security reasons.
Please turn it ON, before you want to local SSH login the container. Reset gateway will
change this option into the default value OFF.
From firmware 2.0.2, the output of the RESTful API to obtain gateway configuration
from AC will be changed (GET http://{your AC domain}/api/cassia/info?mac=
<hubmac>). The container status will be removed from the default API output, to avoid
the oversized UDP packets problem. Container status can be got separately by the
same API with the additional parameter ‘fields=container’. Please refer to SDK WIKI for
details.
From gateway firmware 2.0.2, DNS name server in Cassia Bluetooth gateway will be
propagated into container /etc/resolv.conf. Besides two default DNS name servers
8.8.8.8 and 114.114.114.114 , the container will use the DNS setting in the Network
section of the gateway webpage Config tab as an additional DNS name server. This
feature solves the problem that the firewall blocks two default DNS servers.
Legacy NOTES
Please remember to change the container SSH password upon the first login.
Please implement APP log rotation to avoid flooding container storage. From v1.4.3,
the container can use up to 2.3GB. For the gateways with firmware lower than v1.4.3,
if APP log floods gateway storage, the gateway may be offline and can’t recover by a
reboot. The user has to press the factory reset button to reset the gateway and then
delete the container.
It is suggested to keep the memory usage in the container below 70%. The other 30%
is for peak hours and abnormal cases. It means the container should use less than
90MB, which includes memory used by custom application and all the tools running in
