ETRX35x Development Kit
12.2 Over the Air Firmware Upgrades
Upgrading over the air is possible by cloning a local node’s firmware to a remote node, so if new
firmware has to be introduced to the network it can be downloaded serially to a master node, which
then can clone itself to one node after the other in turn given the target node is only a single hop
away.
Cloning between some firmware releases may not always be possible, so check the
Firmware Revision History for relevant comments. (Not currently enabled in R302C.)
12.2.1 Cloning
In order to clone the local node’s firmware use the command
AT+CLONE:<EUI64 of the target device>:<Target device’s password>
This will initiate the cloning process given the target node is only a single hop from the local node.
After successful cloning the remote node will perform a reset and the local node will continue
normal operation without reset.
12.2.2 Recovering on the default channel
If the target device is reset or power cycled whilst in the bootloader, the unit will listen for new
firmware files on channel 13. It is therefore required to set up a node on channel 13 and repeat
the recovery action described in the previous section.
To set up a node on channel 13 use the following commands:
AT+DASSL – leave the current network (will show an error if not currently part of a network)
ATS00=0004 – Only allow channel 13
AT+EN – establish new network on channel 13
This will cause the local node to become a coordinator on channel 13.
AT+RECOVER
The local node will search for a remote node in bootload mode and clone the local firmware to that
remote node.
